Fatty acid synthase (FASN) serves as the central enzyme in de novo lipogenesis, catalyzing the complete synthesis of palmitate from acetyl-CoA and malonyl-CoA precursors. This multifunctional enzyme complex harbors seven distinct catalytic activities within a single polypeptide chain, making it a critical metabolic hub in both normal physiology and disease states. FASN expression is notably elevated in many cancers, where it supports the increased lipid demands of rapidly proliferating cells, while also playing important roles in cardiovascular biology, neuronal function, and metabolic regulation.
This recombinant monoclonal antibody against human FASN offers the reproducibility and consistency that demanding research applications require. Produced using recombinant technology with a defined sequence, this rabbit IgG clone 2A5 eliminates the lot-to-lot variability inherent in traditional hybridoma-derived antibodies, ensuring your experimental conditions remain stable across long-term studies. The antibody was raised against a synthetic peptide derived from human FASN and purified by affinity chromatography for optimal specificity.
Validation studies demonstrate reliable performance in both immunofluorescence and flow cytometry applications. Immunofluorescence staining of HeLa cells reveals clear cytoplasmic localization patterns consistent with the enzyme's known distribution, while flow cytometric analysis of A549 lung adenocarcinoma cells shows distinct positive population shifts compared to isotype controls. Recommended working dilutions range from 1:20 to 1:200 for both applications, providing flexibility to optimize signal intensity for your specific experimental conditions.
Whether investigating lipid metabolism in cancer progression, exploring metabolic reprogramming in cardiovascular disease, or studying neuronal lipid homeostasis, this antibody provides a dependable tool for visualizing and quantifying FASN expression at the single-cell level.
