Used in research settings to quantify soluble Flt-1 (sFlt-1) levels in biological samples such as serum, plasma, or cell culture supernatants. It is particularly valuable in studies related to angiogenesis, preeclampsia, cancer, and cardiovascular diseases. The kit enables researchers to investigate the role of sFlt-1 as an anti-angiogenic factor by binding VEGF and PlGF, helping to understand disease mechanisms and evaluate potential therapeutic targets. Its high sensitivity and specificity make it suitable for clinical research and biomarker validation studies.
