Synaptotagmin‑1 in Rat Neurons. Synaptotagmin-1 was detected in immersion fixed rat hippocampal neurons (E18) using Mouse Anti-Rat Synaptotagmin-1 Monoclonal Antibody (Catalog # MAB4364) at 10 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 synapses.

Synaptotagmin in Rat Spinal Cord. Synaptotagmin was detected in perfusion fixed frozen sections of rat spinal cord using 8 µg/mL Mouse Anti-Rat Synaptotagmin Monoclonal Antibody (Catalog # MAB4364) overnight at 4 °C. Tissue was stained (red) and counter-stained (green). View our protocol for Fluorescent IHC Staining of Frozen Tissue Sections.

Synaptotagmin-1 in SH-SY5Y Human Cell Line. SH-SY5Y human neuroblastoma cells were cultured overnight in the presence of 1 mM Retinoic Acid (Catalog # 0695/50) prior to immersion fixation. Synaptotagmin-1 was detected using a Mouse Anti-Rat Synaptotagmin-1 Monoclonal Antibody (Catalog # MAB4364). The cells were stained with the NorthernLights 557-conjugated Donkey Anti-Mouse IgG Affinity-purified Secondary Antibody (red; Catalog # NL007). The cell nuclei were counterstained with DAPI (blue). Synaptotagmin-1 immunoreactivity was localized to synaptic vesicles in the cytoplasm and on the plasma membrane. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: Synaptotagmin-1

The Synaptotagmins are a family of integral membrane proteins of synaptic vesicles. Rat Synaptotagmin-1 (Accession # P21707) is a 57 kDa, 421 aa glycoprotein containing two C2 domains related to protein kinase C and sites for palmitoylation and binding of acidic phospholipids, calcium and calmodulin. Synaptotagmin-1 participates in the process of vesicular trafficking and exocytosis by inducing local Ca2+-dependent buckling of the plasma membrane. Rat Synaptotagmin-1 shares 98% aa identity or greater with mouse, human and bovine Synaptotagmin-1.
