Scientific Data Images for Human SNAP25 Antibody

Detection of SNAP25 in A172 (positive) and HL-60 (negative) cells.

SNAP25 was detected in immersion fixed A172 human glioblastoma cells (positive) and absent in HL-60 human acute promyelocytic leukemia cells (negative) using Mouse Anti-Human SNAP25 Monoclonal Antibody (Catalog # MAB11418) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cell cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: SNAP25

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.
