Used in biomedical research to detect and quantify soluble VEGFR-2 (sFLK-1) in pig biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit is particularly valuable in studies related to angiogenesis, vascular development, and endothelial function in porcine models. It supports research in areas like cardiovascular disease, pregnancy-related disorders (e.g., preeclampsia models), and cancer, where sFLK-1 acts as a natural inhibitor of VEGF signaling. The assay enables high sensitivity and specificity, allowing researchers to monitor changes in sFLK-1 levels under experimental conditions or disease states.
