FASN Antibody in Immunofluorescence (IF) — Immunofluorescence analysis of FASN was performed using 70% confluent log phase Hep G2 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with FASN Monoclonal Antibody (C.60.10) (Product # MA5-14887) at 1:50 dilution in 0.1% BSA, incubated at 4 degree Celsius overnight and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin (Panel c: red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

FASN Antibody in Immunofluorescence (IF) — Immunofluorescent analysis of Fatty Acid Synthase in HeLa cells using a Fatty Acid Synthase monoclonal antibody (Product # MA5-14887) (green). Actin filaments are labeled with a fluorescent red phalloidin. DNA is labeled using a fluorescent blue dye.

FASN Antibody in Immunohistochemistry (IHC) — Immunohistochemical analysis of Fatty Acid Synthase in paraffin-embedded breast carcinoma using a Fatty Acid Synthase monoclonal antibody (Product # MA5-14887).

FASN Antibody in Western Blot (WB) — Knockdown of FASN was achieved by transfecting MCF7 with FASN specific siRNAs (Silencer® select Product # s5030). Western blot analysis (Fig. a) was performed using whole cell extracts from the FASN knockdown cells (lane 3), non-specific scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blots were probed with FASN Monoclonal Antibody (C.60.10) (Product # MA5-14887, 1:1000 dilution) and Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25µg/ml, 1:4000 dilution). Densitometric analysis of this western blot is shown in histogram (Fig. b). Decrease in signal upon siRNA mediated knock down confirms that antibody is specific to FASN.

FASN Antibody in Western Blot (WB) — Western blot analysis was performed on whole cell extracts (30 µg lysate) of Hep G2 (Lane 1), HEK 293 (Lane 2), PANC-1 (Lane 3), Caco-2 (Lane 4), A549 (Lane 5), MCF7 (Lane 6), SK-BR-3 (Lane 7), tissue extracts of Mouse Liver (Lane 8), Mouse Adipose (Lane 9) and Mouse Brown Adipose (Lane 10). The blot was probed with Anti-FASN Monoclonal Antibody (Product # MA5-14887, 1:1000 dilution) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/ml, 1:4000 dilution). A 273 kDa band corresponding to FASN was observed across the cell lines and tissues tested.

Product Specific Information

It is not recommended to aliquot this antibody.

Target Information

The enzyme encoded by this gene 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.
