Used in biomedical research to quantify Arginase 1 protein levels in rat biological samples such as serum, plasma, and tissue homogenates. This kit is essential for studying immune responses, particularly in macrophage polarization, where Arg-1 is a marker for M2 macrophages. It supports research in inflammation, infectious diseases, cancer, and autoimmune disorders by enabling accurate measurement of Arg-1 concentration through enzyme-linked immunosorbent assay (ELISA) technique. The high sensitivity and specificity make it suitable for detecting low levels of Arg-1 in small sample volumes.
