Plexin-C1 (extracellular) Blocking Peptide (#BLP-PR091) is the original antigen used for immunization during Anti-Plexin-C1 (extracellular) Antibody (#APR-091) generation. The blocking peptide binds and ‘blocks’ Anti-Plexin-C1 (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.

- Western blot analysis of human HL-60 acute promyelocytic leukemia cell line lysates (lanes 1 and 3) and human Malme-3M melanoma cell line lysate (lanes 2 and 4):
- Expression of Plexin-C1 in in rat dorsal root ganglion.Immunohistochemical staining of perfusion-fixed frozen rat dorsal root ganglion (DRG) sections with Anti-Plexin-C1 (extracellular) Antibody (#APR-091), (1: 200), followed by goat anti-rabbit-AlexaFluor-488. A. Plexin-C1 immunoreactivity (green) appears in DRG neuron profiles (arrows). B. Pre-incubation of the antibody with Plexin-C1 (extracellular) Blocking Peptide (BLP-PR091), suppressed staining. Cell nuclei are stained with DAPI (blue).
- Peptide (C)EVKIQKENDNFNISK, corresponding to amino acid residues 860 - 874 of human Plexin-C1 (Accession O60486).
