Plexin-A2 (extracellular) Blocking Peptide (#BLP-PR082) is the original antigen used for immunization during Anti-Plexin-A2 (extracellular) Antibody (#APR-082) generation. The blocking peptide binds and ‘blocks’ Anti-Plexin-A2 (extracellular) primary antibody, this makes it a good negative reagent control to help confirm antibody specificity in western blot and immunohistochemistry applications. This control is also often called a pre-adsorption control.

- Multiplex staining of Plexin-A2 and p75NTR in rat brainImmunohistochemical staining of perfusion-fixed frozen rat brain sections using Anti-Plexin-A2 (extracellular) Antibody (#APR-082), (1:400) and mouse Mouse Anti-Rat p75 NGF Receptor (extracellular) Antibody (#AN-170), (1:300). A. Sections of rat horizontal diagonal band (HDB) were stained for PLXNA2 (green). B. Same sections were stained for p75NTR (red). C. Merge of the two images reveals cells expressing both PLXNA2 and p75NTR (horizontal arrows), cells expressing only PLXNA2 (upwards pointing arrows) or cells expressing only p75NTR (downwards pointing arrows) can also be observed. Cell nuclei are stained with DAPI (blue).
