Human Phospho-FYN (Y530) PharmaGenie ELISA Kit (SBRS1838)

Built around a phosphorylation-site-specific capture antibody, this kit from Assay Genie quantitatively measures the 59 kDa FYN tyrosine kinase phosphorylated at its inhibitory Y530 residue in human cell lysates and tissue lysates. FYN is a Src-family non-receptor tyrosine kinase whose catalytic output is held silent by C-terminal Y530 phosphorylation, and loss of that phospho-mark is a canonical indicator of activation in T-cell receptor signaling, neuronal development and synaptic-plasticity research, and in oncogenic-transformation studies of hematological malignancies. The kit is supplied as 96 assays on a single microplate and uses a colorimetric readout that runs on standard plate readers, supporting side-by-side comparison of basal versus ligand-stimulated phosphorylation in matched samples. Reagents are sized to carry the full plate from lysate preparation through detection without additional purchases, components should be kept refrigerated upon receipt to preserve antibody activity, and the kit is intended for in vitro research use only in academic and biopharma laboratories working on Src-family kinase signaling.
