Used in biomedical research to quantify levels of VEGF-D in biological samples such as serum, plasma, and cell culture supernatants. Plays a key role in studies related to lymphangiogenesis and angiogenesis, helping researchers investigate tumor metastasis, cancer progression, and the development of lymphatic-related diseases. Commonly applied in oncology, cardiovascular research, and inflammatory disease studies to assess VEGF-D expression under various experimental conditions. Supports the evaluation of therapeutic responses in preclinical models by providing sensitive and specific detection of VEGF-D protein concentration changes.
