Used in biomedical research to quantify mouse endostatin levels in biological samples such as serum, plasma, and tissue homogenates. This ELISA kit enables researchers to study angiogenesis regulation, particularly in cancer research, where endostatin plays a role in inhibiting blood vessel formation. It is also applied in studies related to tumor growth, metastasis, and response to anti-angiogenic therapies. The assay provides a sensitive and specific method for monitoring endostatin concentration in experimental models, supporting investigations in immunology, oncology, and vascular biology.
