Used in biomedical research to detect and quantify SH2-carrying proteins such as SHC and SLP-76 in cell lysates or tissue samples. These proteins play key roles in intracellular signaling pathways, especially those involving immune cell activation and growth factor receptors. The ELISA kit enables researchers to monitor changes in protein expression or phosphorylation states under various experimental conditions, including drug treatment, gene knockdown, or disease models. It is widely applied in immunology, oncology, and signal transduction studies to better understand cellular responses and identify potential therapeutic targets.
