HQ-O Ready-To-Dilute (RTDTM) Stain Reagent is designed to label amyloid plaques in paraffin-embedded or freshly cut frozen tissue sections. As a fluorescent zinc chelator, HQ-O is unique as it takes advantage of the known presence of concentrated zinc in amyloid plaques. Studies with HQ-O revealed that fluorescent plaque-like structures are only seen when synthetic A?x-42 is aggregated in the presence of zinc. Under blue light excitation, plaque structures appear bright green fluorescent in the brain parenchyma, correlating closely with plaque structures observed following A? antibody staining. HQ-O RTDTM staining reagent is compatible with other fluorophores, such as DAPI, Hoechst and ethidium bromide, as well as fluorescent-labelled antibodies with emission spectra in the blue and/or red emission range of fluorescent microscopes. Due to its zinc-chelating characteristics, HQ-O RTDTM staining reagent may visualize globular structures within blood vessels and intravascular leucocytes. HQ-O RTDTM staining reagent has multiple advantages over older blue-light exciting stains such as Thioflavin S. Thioflavin S typically exhibits relatively low contrast and resolution and suffers from bleed-through when excited by wavelengths other than blue light. HQ-O RTDTM staining reagent suffers none of these setbacks and not only provides a higher contrast and longer lasting dye, but because it lacks excitation bleed-through, HQ-O can be readily adapted to multiple labelling studies very easily. To visualize the HQ-O tracer, it is recommended to use a filter cube designed for visualizing Fluorescein/FITC or a blue-light laser. Although it can be seen with both narrow and wide-band pass filters, there is no need to use a narrow band filter since the compound does not bleed through when excited with other filters. A recommended excitation range of a wide band filter is 447-503 nm, with a peak at 475.
Background Info:
A novel zinc chelator, HQ-O, was developed for localizing zinc within amyloid plaques. The histology involves incubating tissue sections in a dilute aqueous solution of HQ-O.

The Biosensis AG-400-AG kit utilizes an ethidium bromide counter stain for a quick and effective way to visualize cell nuclei and cell bodies of cells while under UV illumination allowing the assessment of amyloid plaques and cell/tissue positioning as well in one step. Amylo-Glo RTD Ready 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 RTD is 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).

The causes and effects of neuronal degeneration are of major interest to a wide variety of neuroscientists. Paralleling this growing interest is an increasing number of methods applicable to the detection of neuronal degeneration. Fluoro-Jade C stains all degenerating neurons regardless of specific insult or mechanism of cell death. Fluoro-Jade C exhibits the greatest signal to background ratio, as well as the highest resolution. This translates to a stain of maximal contrast and affinity for degenerating neurons. This makes it ideal for localising not only degenerating nerve cell bodies but also distal dendrites, axons and terminals. The dye is highly resistant to fading and is compatible with virtually all histological processing and staining protocols. Note: This product is equivalent to discontinued product AG325 from Merck-Millipore.

Use:

Kit Components:
Materials Provided: 30 mg Fluoro-Jade C, dry powder Detailed protocol Equipment and Reagents Required: Distilled water ACS grade Ethanol (200 proof) for slide & solution preparation 1% sodium hydroxide in 80% ethanol (basic alcohol solution) 0.1% Acetic Acid solution (in water) 70% ethanol in distilled water 0.06% (KMnO4) potassium permanganate solution DAPI powder or 100X solution (working range is 0.5-5 µg/mL) Xylene liquid Staining dishes/Coplin jars Cover slips DPX mounting media or another permanent mounting medium. Non-polar media are preferred over aqueous mounting media such as glycerin/water to obtain high- contrast images (refer to Appendix B in the protocol for a comparative analysis). Traditional fluorescent mounting mediums are not recommended because of their high pH. Slide warmer Convection oven
Specificity:
Degenerating neurons, and neuronal degeneration. There is no specific staining in normal healthy brain. Note: Some researchers under some conditions report blood vessel staining with Fluoro Jade. This may be because Fluoro Jade is an analogue of eosin (which stains blood cells). In general, good perfusion and preparation of the tissue should help prevent blood vessel staining but it may not be possible to eliminate it entirely. In our experience it is generally possible to distinguish neuronal from blood vessels staining by eye.
Purification:
Silica TLC (acetanitrile/water, 6/4) revealed the presence of 2 fluorescent spots, presumably corresponding to the mono and di sulphate homologues. The presence of precursors or free fluorescein was not detected.
The causes and effects of neuronal degeneration are of major interest to a wide variety of neuroscientists. Paralleling this growing interest is an increasing number of methods applicable to the detection of neuronal degeneration. The fluorescent dye Fluoro-Jade B (FJB), like its more purified brother Fluoro-Jade C (FJC), is an anionic fluorescein derivative useful for the histological staining of neurons undergoing degeneration. Fluoro-Jade B differs from FJC in that it is a slightly less refined chemical formulation and thus it does not quite provide the same level of signal to noise or high resolution as FJC. Nonetheless FJB is still widely used and works very well as a marker of degenerating neurons and even glia (see Damjanac M et al., <a href="https://pubmed.ncbi.nlm.nih.gov/17125750/" target="_blank"> Brain Res. 2007;1128(1):40-9). FJB operates nearly identically in protocol to that of FJC, and Fluoro-Jade B is compatible with several other labeling procedures including immunofluorescent and fluorescent Nissl techniques. Fluoro-Jade B stains all degenerating neurons regardless of specific insult or mechanism of cell death. Fluoro-Jade B exhibits the greatest signal to background ratio, as well as the highest resolution. This translates to a stain of maximal contrast and affinity for degenerating neurons.

Black-Gold II is a novel haloaurophosphate complex which localises myelin within the central nervous system. The Black Gold II Ready-to-Dilute (RTD) Staining Kit allows you to localise myelin, both individual fibres and tracts, along with the option of co-localising cell bodies via the Toluidine Blue counter stain. Black Gold II labelled myelinated fibres appear nearly black while the Toluidine Blue O labelled cellular Nissl bodies are blue under bright field illumination. Black Gold II can demonstrate and characterise specific myelin changes associated with exposure to diverse neurotoxicants including kainic acid, domoic acid, 3-nitropropionic acid, Fluoro-Gold and isoniazid. Black Gold II can also be combined with other histochemical markers including Nissl stains, retrogradely transported fluorescent tracers and fluorescent markers of neuronal degeneration. The advantages associated with the Black-Gold II include high resolution, high contrast, short histochemical processing time, versatility and consistent reproducibility.

Applications:

Application Details:
Black Gold II is a high resolution myelin stain with amyloid plaque counter stain. Its use is tailored to studies using formalin or paraformaldehyde fixed, non-paraffin embedded, non-solvent processed brain tissue. It can be used with both thick and thin sections. For thick sections, gelatin coated slides or slides specially designed to bind tissues sections should be use to avoid section loss. Free-floating sections can be used as well but sections are easier to handle and transfer when mounted on slides. A suggested method for thick sections is provided as a guide: Either frozen or vibratome sections are cut at a thickness of 20-50 ?m and collected in 0.1 M neutral phosphate buffer. The sections are then typically mounted on 1% gel-coated slides and then air dried on a slide warmer (at 50°C) for at least an hour until throughly dried and adhered to the slide. The sections can be stained loose, although the sections are easier to handle when mounted on slides. The mounted sections were rehydrated in distilled water for 2 minutes before being processed in the staining solutions.
