SNAP25 Antibody (1079626) [Unconjugated]

Western Blot shows lysates of human cerebellum tissue. PVDF membrane was probed with 2 µg/ml of Mouse Anti-Human SNAP25 Monoclonal Antibody (Catalog # MAB11729) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for SNAP25 at approximately 26 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

SNAP25 was detected in immersion fixed paraffin-embedded sections of human hypothalamus using Mouse Anti-Human SNAP25 Monoclonal Antibody (Catalog # MAB11729) at 1 µg/ml for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001) or the HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to synapses.

SNAP25 was detected in immersion fixed paraffin-embedded sections of human brain cortex using Mouse Anti-Human SNAP25 Monoclonal Antibody (Catalog # MAB11729) at 5 µg/ml overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using the HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007) and counterstained with hematoxylin (blue). Specific staining was localized to the vesicles.

Background

SNAP25 (Synaptosomal associated protein of 25 kDa; also SUP) is a cytosolic 24-29 kDa member of the SNAP25 family of proteins. It is expressed in neurons, beta ‑cells, and adrenal chromaffin cells. SNAP25 is involved in vesicle exocytosis, where two presynaptic SNAP25, and one syntaxin‑1 molecule associates with vesicle membrane VAMP2 to form a alpha ‑helix via a zipper‑like mechanism. This approximates two membranes, which subsequently fuse to create a pore. Human SNAP25b is 206 amino acids (aa) in length. It contains two t‑SNARE coiled‑coil homology domains (aa 19‑81 and 140‑202) and a proteolytic cleavage site at Arg180:Ile181. Palmitoylation occurs between aa 85‑92; phosphorylation occurs on Thr138. There are three isoform variants. One shows nine aa changes over aa 58‑89 (isoform a), a second shows a 30 aa substitution for aa 1‑94, while a third contains an alternative start site at Met64. Full‑length human and mouse SNAP25 are identical in amino acid sequence.
