Used in biomedical research to detect and quantify Angiopoietin-4 protein levels in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit is particularly valuable in studies related to vascular development, inflammation, and endothelial cell function. It supports research into diseases involving angiogenesis, including cancer, diabetic retinopathy, and cardiovascular disorders. The assay provides high sensitivity and specificity, enabling accurate measurement of ANG-4 concentrations for both basic research and preclinical evaluation.
