Used in biomedical research to quantify Angiopoietin-like Protein 4 levels in biological samples such as serum, plasma, and cell culture supernatants. Enables investigation of ANGPTL4's role in metabolic regulation, including lipid metabolism and insulin sensitivity. Widely applied in studies related to obesity, diabetes, and cardiovascular diseases. Supports research on angiogenesis and tumor progression due to ANGPTL4's involvement in blood vessel formation and cancer cell survival. Provides a reliable, sensitive, and specific method for detecting protein expression changes in experimental models and clinical samples.
