| PEP-FAM-WOOD01 | 5-FAM labeled Woodtide acts as specific fluorescent substrate for Src tyrosine kinase, quantifies kinase activity via fluorescent signal for Src pathway inhibitor screening and intracellular phosphorylation imaging research | 5-FAM-Woodtide is N-terminally 5-FAM modified nonapeptide substrate, carrying specific tyrosine phosphorylation motif recognized by Src family kinases. Activated Src catalyzes phosphorylation on the tyrosine residue of this substrate; phosphorylated product can be captured by phosphotyrosine-specific antibodies. The intrinsic green fluorescence supports quantitative detection via laser confocal microscopy and flow cytometry. Widely applied for in vitro quantitative Src kinase activity, high-throughput screening of small-molecule Src/FAK pathway inhibitors, in situ intracellular Src phosphorylation imaging in tumor cells and research on tyrosine kinase signal transduction, suitable for molecular pharmacology, tumor signaling pathway and kinase drug screening laboratories | Molecular pharmacology, Src tyrosine kinase assay, tyrosine phosphorylation imaging, kinase inhibitor screening, intracellular tumor signaling pathway, fluorescence quantitative kinase assay | Src family tyrosine kinase, phosphotyrosine antibody, FAK downstream signaling molecule, fluorescence detection channel |
