Product Image Gallery

FASN Antibody in Immunohistochemistry (IHC) — **Detection of human FASN by immunohistochemistry.** *Sample:* FFPE section of human prostate carcinoma. *Antibody:* Affinity purified rabbit anti-FASN (Cat. No. A301-323A) used at a dilution of 1:200 (1µg/ml). *Detection:* DAB.

FASN Antibody in Western Blot (WB) — **Detection of human FASN by western blot and immunoprecipitation.** *Samples:* Whole cell lysate from HeLa (5, 15 and 50 µg for WB; 1 mg for IP, 20% of IP loaded) and 293T (T; 50 µg) cells. *Antibodies:* Affinity purified rabbit anti-FASN antibody A301-323A used for WB at 0.04 µg/ml (A) and 0.1 µg/ml (B) and used for IP at 3 µg/mg lysate. FASN was also immunoprecipitated by rabbit anti-FAS antibodyA301-324A, which recognizes a downstream epitope. *Detection:* Chemiluminescence with exposure times of 30 seconds (A and B).

Target Information

Fatty acid synthase is a multifunctional protein. Its main function is to catalyze the synthesis of palmitate from acetyl-CoA and malonyl-CoA, in the presence of NADPH, into long-chain saturated fatty acids. In some cancer cell lines, this protein has been found to be fused with estrogen receptor-alpha (ER-alpha), in which the N-terminus of FAS is fused in-frame with the C-terminus of ER-alpha.
