Used in biomedical research to detect and quantify endostatin levels in rat biological samples such as serum, plasma, and tissue homogenates. This kit is essential for studying angiogenesis regulation, particularly in cancer research where endostatin plays a role in inhibiting tumor growth by blocking blood vessel formation. It is also applied in inflammation and autoimmune disease studies, helping researchers evaluate the effectiveness of therapeutic agents targeting angiogenic pathways. The assay provides high sensitivity and specificity, enabling accurate measurement in experimental models.
