Used to measure Angiopoietin-2 (ANG-2) levels in biological samples such as serum, plasma, or cell culture supernatants. It is commonly applied in research settings to study angiogenesis, vascular stability, and inflammatory processes. Elevated ANG-2 levels are associated with various pathological conditions including cancer, sepsis, diabetic retinopathy, and cardiovascular diseases. This kit enables researchers to quantify ANG-2 accurately, supporting studies on disease progression, therapeutic response, and underlying molecular mechanisms in vascular biology.
