Soluble oligomeric assemblies of the Amyloid-β peptide are today anticipated to be the direct cause regarding the Alzheimer pathology. As a consequence, oligomeric Aβ-assemblies constitute a very interesting therapeutic target. Identification of Aβ-oligomers is however, technically challenging due to there labile nature and low abundance. Abeta oligomer-specific OMAB antibody is based on the IgM isotype and represents a new concept of Aβ-oligomer binders using a combination of high avidity and very low monovalent affinity. This combination creates a selectivity of the antibody towards the oligomeric fraction and minimizes reactivity towards monomeric species.

The oligomeric form of Amyloid Beta peptide (A?, 1-42) has been closely linked to Alzheimer's Disease. Several ELISAs targeting A? have been developed; however, these ELISAs are known to cross-react with Amyloid Beta precursor protein (APP) and are poorly characterized against monomeric and oligomeric forms of the peptide. The Biosensis MOAB-2 antibody, developed by LaDu and co-workers (Youmans K. et al., 2012), has been shown to specifically detect A?, but not the precursor molecule APP. When utilized in ELISAs, the oligomeric form of A? peptide (o-A?) can be assayed independently of the other forms of the molecule when assayed with the MOAB-2 monoclonal antibody. The Biosensis oligomeric A? ELISA kit is a sandwich ELISA that allows the preferential quantification of oligomeric A? peptides. This kit is exclusive to Biosensis and consists of a pre-coated mouse monoclonal anti-A? capture antibody (MOAB-2), a biotinylated MOAB-2 detection antibody and horseradish peroxidase (HRP)-conjugated streptavidin. The addition of a substrate (3,3',5,5'-tetramethylbenzidine, TMB) yields a colored reaction product which is directly proportional to the concentration of o-A? present in samples and protein standards. The purpose of this kit is the in vitro qualitative measurement of oligomeric A? peptide levels in brain extracts and CSF samples from both transgenic mice and humans relative to a known o-A? standard. The inclusion of a highly validated oligomeric standard results in a unique, ready-to-use ELISA kit.This kit has been configured for research use only and is not to be used in diagnostic or clinical procedures.

Amyloid beta research | Oligomeric Human beta-Amyloid A?1-42 Peptide, Stabilized (PE-1750-1000)Beta-Amyloid A?1-42 Peptide, HFIP-treated (PE-1749-50)
The amyloid beta peptide is derived from the cleavage of the Amyloid precursor protein (APP) and varies in length from 39 to 43 amino acids. However, the form(s) of amyloid-beta peptide (A?) associated with the pathology characteristic of Alzheimer's disease (AD) remains unclear. In particular, the neurotoxicity of intraneuronal A? accumulation is an area of considerable research and controversy principally because antibodies thought to be specific for A? have been shown to actually detect intraneuronal APP and not A? exclusively.MOAB-2 (mouse IgG2b) is a pan-specific, high-titer antibody to A? residues 1-4 as demonstrated by biochemical and immunohistochemical analyses (IHC), and is highly specific just to amyloid beta peptide.MOAB-2 did not detect APP or APP-CTFs in cell culture media/lysates (HEK-APPSwe or HEK APPSwe/BACE1) or in brain homogenates from transgenic mice expressing 5 familial AD (FAD) mutation (5xFAD mice). Using IHC on 5xFAD brain tissue, MOAB-2 immunoreactivity co-localized with C-terminal antibodies specific for A?40 and A?42. MOAB-2 did not co-localize with either N- or C-terminal antibodies to APP. In addition, no MOAB-2-immunreactivity was observed in the brains of 5xFAD/BACE-/- mice, although significant amounts of APP were detected by N- and C-terminal antibodies to APP, as well as by 6E10.In both 5xFAD and 3xTg mouse brain tissue, MOAB-2 co-localized with cathepsin-D, a marker for acidic organelles, further evidence for intraneuronal A?, distinct from A? associated with the cell membrane. MOAB-2 demonstrated strong intraneuronal and extra-cellular immunoreactivity in 5xFAD and 3xTg mouse brain tissues.

Western Blotting (WB), Immunohistochemistry (IH), Immunohistochemistry/paraffin embedded IH(P), Immunoprecipitation (IP), Immunofluorescence (IF), ELISA.Antibody has been tested in WB using purified synthetic beta-amyloid preparations and from transgenic mouse brain formic acid extracts (see figure 1). Formic acid extraction/concentration is required for western blot detection from extracts. MOAB-2 antibody is specific for beta-amyloid and does not detect APP. Suggested dilution of 1:2000-1:5,000 for WB, standard ECL detection systems. Tissue samples for the detection of beta-amyloid should be prepared as detailed in K.L. Youmans et al. {Journal of Neuroscience Methods 196 (2011) 5159} for best results. Detection of beta-amyloid 40/42 in direct westerns can be difficult; Dot-blots of prepared samples are recommended as detailed in Youmans. KL et al 2012. IR or fluorescent detection systems not yet tested, they but are expected to work well with higher primary antibody dilutions because of the increased sensitivity of the detection methods.Suggested dilutions for IHC are 1:50-1:1,000. Fresh frozen, 4% paraformaldehyde fixed frozen, or formalin fixed paraffin embedded tissues are all suitable. Optimal dilutions must be determined by the end user. Antigen retrieval is required in fixed tissues for optimal staining.Antibody was tested on 4% paraformaldehyde/0.1% glutaraldehyde fixed frozen tissue from 3xTg and 5xFAD mice. MOAB-2 antibody detects intraneuronal and extracellular beta-amyloid in IHC and does not detect APP {Youmans KL et al 2012}. The antibody also reacts with archival formalin-fixed, paraffin-embedded tissue samples with antigen Heat Induced Epitope Retrieval (HIER): Recommended Citrate, pH 6.0 buffer for HIER. Signal was weak without antigen retrieval. Immunoreactively was expressed in intraneural-amyloid deposition (plaque) in Alzheimer's brain. MoAB-2 was found to be extremely clean and with an excellent signal to noise ratio with no neuro-cellular diffusive staining.In addition MOAB-2 demonstrated no significant differences in A? detection using paraffin fixed, free-floating sections {Youmans KL et al 2012}. Formic acid (FA) treatment resulted in optimal detection of both intraneuronal and extracellular A? compared to without FA (incubated in 88% FA 8 min, Youmans KL et al 2012). Free floating tissue sections were permeabilized in TBS containing 0.25% Triton X-100 (TBSX; 3 Ã 10 min), blocked with 3% horse serum in TBSX (3 Ã 10 min) followed by 1% horse serum in TBSX (2 Ã10 min) and incubated with appropriate primary antibodies diluted in TBSX containing 1% horse serum overnight. See Youmans KL et al 2012 for full IH(P) protocol and method details. For IF, suggested dilution is 1:100-1:500. The antibody was tested on 4% PFA fixed frozen tissue. Fixed tissues were washed in TBS (3 Ã 10 min), then incubated in 88% FA (8 min), and then permeabilized in TBSX (3 Ã 10 min), and blocked in TBSX containing 5% bovine serum albumin (BSA; 1 hr). Sections were subsequently incubated with appropriate primary antibodies diluted in TBSX containing 2% BSA overnight on an oscillatory rotator. Detection was via fluorescently labelled absorbed secondary antibodies {Youmans KL et al 2012}.For IP, the suggested dilution is 1:200 to 1:1,000 for labeled beta-amyloid using Protein A/G conjugated beads as the capture vehicle {Youmans KL et al 2012}.In an ELISA, a dilution of 1:50-1:1000 is suggested. The antibody has been tested in ELISAs on synthetic beta-amyloid and tissue homogenates from beta-amyloid-Tg mice. Biosensis recommends optimal dilutions/concentrations should be determined by the end user for all applications. Dilutions provided are only meant to serve as a basic guide.

MOAB-2 detects preparations enriched in U-, O-, F-A?42, and U-A?40 by dot-blot, and is thus a pan-specific A? antibody. However, MOAB-2 is selective for the more neurotoxic A?42 compared to A?40. Indeed, MOAB-2 demonstrated a titration against antigen concentration, and detects A?40 at 2.5 pmol but U-, O- and FA?b42 at antigen concentrations as low as ~ 0.1 pmol {Youmans. KL et al 2012}. MOAB-2 does not detect APP (Amyloid precursor protein). | Human, Rat, other species not yet tested.By Dot blot, MOAB-2 detected rat A?40 and human A?40, albeit with less affinity than for A?42. {Youmans.

Biotinylated MOAB-2 antibody may also help to reduce background staining in difficult-to-stain tissues and increase detection sensitivity. The ability of biotinylated MOAB-2 antibody to detect amyloid beta has been validated by IHC.Purified, non-biotinylated MOAB-2 antibody is available here.

Mix the A? monomer with its complex partner (eg., lipoprotein) at desired concentrations in PBS, pH 7.4, or other suitable buffers compatible with its intended application7. Incubate at room temperature for 2 hours without shaking8. Use complexes immediately after incubationThese protocols are based on procedures published by Youmans KL et al., 2012 and Tai LM et al., 2013, and we refer to these publications and other relevant literature for further details.Provided working concentrations are only meant to guide the user. Optimal concentrations depend on the experimental design and need to be determined empirically.
A proprietary preparation of human amyloid beta peptide (amino acids 1-42) that was initially monomerized by HFIP-treatment and then allowed to form oligomers by the procedure described in Youmans KL et al., 2012, followed by lyophilisation using Biosensis' proprietary stabilization procedures.The resulting oligomeric mixture has been specially designed to allow the formation of stable, oligomeric A?1-42 peptide, multimeric complexes or oligomers. The material is intended to be used as a stable and consistent standard or positive control for oligomeric ELISA assays, as well as other research applications.
Product Type:
Peptides/Controls
Format:
Lyophilized, Supplied as 2 x 500 ng vials, each containing lyophilized A? oligomers. Note that the amount of provided oligomeric protein is based on the amount of monomeric A? used to form these oligomers. The precise formation, size and number of oligomers cannot be quantified by any known method.
Storage Temp:
Store unopened, lyophilized oligomeric A? with desiccant, insulated, at -20 °C short term, -80 °C long term. Store reconstituted vial at 2- 8 °C for up to 2 days. The reconstituted material should not be frozen for best results.
Use as positive control in Oligomeric A? ELISA Kit (BEK-2215): Reconstitute one vial with 1 mL of assay buffer provided in the ELISA kit. Dilute to a concentration of 0.5-1 ng/mL. At this concentration, a positive signal will be obtained within the dynamic range of the calibration curve.Use as oligomeric A-beta peptide standard in Oligomeric A? ELISA Kit (BEK-2215): Reconstitute one vial with 1 mL of assay buffer provided in the ELISA kit. Dilute to a concentration of 2 ng/mL, which represents the highest concentration of the calibration curve. Perform a 1:2 serial dilution down to 0.031 ng/mL in assay buffer. Click here for detailed instructions on generating a calibration curve with PE-1750-1000.Use as positive control in other applications: Optimal concentrations need to be determined empirically. It is recommended to reconstitute the vial with 100 200 uL buffer first (eg., PBS, pH 7.4), and prepare further working dilutions thereof.
The beta Amyloid peptide is derived from the cleavage of the Amyloid precursor protein and varies in length from 39 to 43 amino acids. Beta amyloid peptides are the major constituents of the plaques and tangles that occur in Alzheimer's disease.

Amylo-Glo® RTDReady to Dilute Staining reagent is designed to stain amyloid plaques in tissue sections. This novel marker has several advantages over other conventional markers such as Thioflavin S and Congo Red because of its unique chemical and spectral properties. (L. Schmued et al. (2012) J.Neuroscience Methods 209:120 126). Using Amylo-Glo® results in a very bright blue UV excitable stain under physiological conditions that will not bleed through when illuminated with other filters. Its brightness makes it ideal for low magnification quantification studies, while its unique excitation/emission profile and mild staining conditions makes it ideal for combination for multiple immunofluorescent labeling studies. Amylo-Glo® RTDis compatible with fresh, frozen, and formalin-fixed immunohistochemistry or cytochemistry, and it is particularly good for confocal and multiple labeling because of its high fluorescent intensity and high resistance to photo-bleaching. Moreover because Amylo-Glo® fluoresces in the UV channel, double and triple labeling experiments can be performed very easily (see protocol).
