Used in biomedical research to quantify mouse angiopoietin-4 (ANG-4) levels in biological samples such as serum, plasma, and tissue homogenates. This ELISA kit is particularly useful in studies related to vascular development, inflammation, and endothelial cell function. Researchers apply it in immunology and cancer research to investigate the role of ANG-4 in angiogenesis and immune regulation. The assay enables high sensitivity and specificity, allowing detection of subtle changes in protein expression during disease progression or therapeutic intervention.
