Used in biomedical research to quantify levels of human fatty acid synthase (FAS) in biological samples such as serum, plasma, and tissue lysates. This kit enables researchers to study the role of FAS in metabolic disorders, obesity, insulin resistance, and cancer, where FAS overexpression is often observed. It is particularly valuable in drug development and metabolic studies, allowing assessment of FAS expression changes in response to therapeutic agents or genetic manipulations. The assay provides high sensitivity and specificity, making it suitable for both clinical research and laboratory investigations into lipid metabolism and related diseases.
