The antibody has a proven strong Biotin-Streptavidin/HRP immunostaining at a 1/500-1/1000 dilution in rat hypothalamus and spinal cord.
The specificity of the antiserum was examined by soluble pre-adsorption with the peptides in question at a final concentration of 10-6M CCK-8 immunolabeling was completely abolished by pre-adsorption with CCK-8, gastrin 17 and gastrin 34. Pre-adsorption with the following peptides resulted in no reduction of immunostaining: α-CGRP, Ÿ-CGRP, neurotensin, somatostatin, substance P, leucine enkephalin, methionine enkephalin, VIP, neuropeptide Y, gastric inhibitory polypeptide, bombesin, glucagon, peptide YY, and FMRF amide.
Product Description: Low magnification IHC image of neurons staining for CCK-8 in the dorsal horn of the rat spinal cord (above), and in the rat hippocampus (below). The tissue was fixed with 4% formaldehyde in phosphate buffer, before being removed and prepared for vibratome sectioning (hippocampus) and frozen sectioning (spinal cord). Sections were incubated at RT in 10% goat serum in PBS, before standard IHC procedure. Primary antibody was incubated at 1:1000 for 48 hours, goat anti-rabbit secondary was subsequently added for 1 hour after washing with PBS. Light microscopy staining was achieved with standard biotin-streptavidin/HRP procedure and DAB chromogen.
