Data Examples

Western Blot Detection of Rat VAP‑B by Western Blot. View Larger

Detection of Rat VAP‑B by Western Blot. Western blot shows lysates of PC‑12 rat adrenal pheochromocytoma cell line. PVDF membrane was probed with 0.5 µg/mL of Mouse Anti-Rat VAP‑B Monoclonal Antibody (Catalog # MAB7329) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for VAP‑B at approximately 28 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Immunohistochemistry VAP‑B in Rat Brain. View Larger

VAP‑B in Rat Brain. VAP‑B was detected in perfusion fixed frozen sections of rat brain (medulla) using Mouse Anti-Rat VAP‑B Monoclonal Antibody (Catalog # MAB7329) at 8 µg/mL overnight at 4 °C. Tissue was stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to gigantocellular neurons. View our protocol for Fluorescent IHC Staining of Frozen Tissue Sections.

Background: VAP-B

Vesicle-associated membrane protein (VAMP)-associated protein B (VAP-B; also VAMP-B) is an ~30 kDa ubiquitously expressed type IV transmembrane protein belonging to the VAP family. It is found in endoplasmic reticulum (ER), Golgi and other membranes as a homodimer or a heterodimer with VAP-A, probably associating through the transmembrane regions. Human VAP-B cDNA encodes a 222 amino acids (aa) cytoplasmic domain and a 21 aa C-terminal membrane anchor. Rat VAP-B shares 89% and 96% aa identity with mouse and human VAP-B, respectively. A soluble form can function as a ligand for EPH receptors. A human polymorphism of VAP-B, P56S, is found in three familial motor neuron diseases, notably the amylotrophic lateral sclerosis variant ALS8.
