Anti-SAR1A Antibody

A small GTPase involved in COPII vesicle formation at ER exit sites, SAR1A drives coat recruitment for anterograde transport from the endoplasmic reticulum to the Golgi apparatus. The unconjugated IgG polyclonal reagent from Antibodies.com was raised in rabbit and recognizes the SAR1A target in human, mouse, and rat samples across western blot and immunohistochemistry workflows. Supplied as 50 µl of ready-to-use antibody, it suits labs profiling COPII-dependent trafficking, mapping secretory pathway dynamics, or probing SAR1A expression in fixed tissue sections and cell lysates. The polyclonal format broadens epitope coverage relative to a monoclonal clone, which helps when single-epitope reagents give weak or inconsistent signal under varying fixation or lysis conditions.
