Used in research settings to quantify levels of pigment epithelial-derived factor (PEDF) in biological samples such as serum, plasma, and cell culture supernatants. This assay is commonly applied in studies related to eye health, particularly in age-related macular degeneration and diabetic retinopathy, where PEDF plays a protective role in retinal cells. It is also utilized in cancer research due to PEDF’s anti-angiogenic properties, helping assess its expression in tumor environments. Additionally, the kit supports investigations in neurodegenerative diseases and metabolic disorders, where PEDF levels correlate with inflammation and insulin resistance. The ELISA format allows for high sensitivity and specificity, making it ideal for detecting low concentrations of PEDF in small sample volumes.
