Affinity Biosciences - The phospho-antibody specialist


Affinity Biosciences is a provider of innovative tools for signal transduction research with a focus on well validated phospho-specific antibodies.


Use our search to find your antibody (e.g. Ser724, IRE1 or Phospho-IRE1 etc).


Well validated phospho-specific antibodies

Validation is important for any antibody, but for Phospho-specific antibodies it is even more important as specificity is truly key to their usefulness.


Affinity Biosciences antibody validation begins with Mass Spec (MS) analysis of the blocking peptide to ensure the peptide has been produced correctly, followed by checking that the peptide blocks the antibody well in Western blotting with research samples showing that the antibody corresponds correctly to the blocking peptide.


DATASHEET IMAGES: Images of Western blots are provided on the datasheets showing blocking and control lanes (without the peptide) to show binding of the target along with images of other applications such as Immunohistochemistry, immunofluorescence etc as appropriate.


As an example, details of the validation of our Phospho-IRE1 (Ser724) - AF7150 antibody have been provided below:

Affinity also produce more than 500 inhibitors and SiRNAs.


Additionally all affinity products are covered by our 100% antibody guarantee, so you can try them without worrying whether they will work. We know they work well, but we understand you may be sceptical having tried other antibodies in the past, so now you can try them without worrying.

If they don't work, we'll give you your money back.

Anti-RAMP Antibodies (1, 2 and 3)


Receptor Activity Modifying Proteins (RAMPs) are required to transport calcitonin-receptor-like receptor (CRLR or CALCRL) to the plasma membrane. CRLR is a G protein-coupled receptor receptor with seven transmembrane domains, which can function as either a calcitonin-gene-related peptide (CGRP) receptor or an adrenomedullin receptor, depending on which members of the RAMP family are expressed. 


Wth RAMP1 it produces a CGRP receptor with RAMP2 it produces an adrenomedullin (AM) receptor (AM1) with RAMP3 it produces a dual CGRP/AM receptor (AM2)


In general four roles have been reported for RAMPs:

1. RAMPs enable the forward-trafficking of some GPCRs to the cell surface.

2. RAMPs can alter GPCR pharmacology, switching ligand selectivity for some GPCRs.

3. RAMPs can influence coupling to GPCR signaling pathways.

4. RAMPs may alter the trafficking pathway of some GPCRs from the cell surface, with different RAMPs controlling receptor fate through recycling or degradative pathways.

Anti-DNA damage-binding protein 1


DNA damage-binding protein 1 (DDB1) is the large subunit (p127) of the heterodimeric DNA damage-binding (DDB) complex. DDB1 also functions as a core component of the cullin 4 (CUL4) ubiquitin E3 ligase complex, facilitating the binding of substrates to this complex and the ubiquitination of proteins. These factors (ubiquitin ligase substrates) regulate numerous essential processes in the cell including DNA repair (DDB2), DNA replication, chromatin remodelling (Cdt2) and more.


Applications: WB           Host: Rabbit      Reactivity: Human
