Anti-FASN Antibody

This rabbit polyclonal antibody targets FASN (Fatty Acid Synthase), a homodimeric ~270 kDa multifunctional enzyme that catalyzes the de novo synthesis of long-chain fatty acids from acetyl-CoA and malonyl-CoA. Provided by Antibodies.com as 200 µl of unconjugated IgG antiserum, the reagent is validated for western blot detection of endogenous FASN in human, mouse, and rat samples.

FASN expression is widely studied in metabolic disease and oncology research, where elevated lipogenesis is associated with tumor proliferation, fatty liver progression, and insulin resistance. Researchers use this antibody to probe whole-cell lysates and tissue homogenates, typically resolving FASN near the 270 kDa marker on SDS-PAGE gels. Store the vial at -20 °C; aliquot upon first use to limit freeze-thaw cycles and preserve binding activity across long-term experiments.
