pp60c-Src is the prototype non-receptor tyrosine kinase. Homology to Src in three regions is shared by a number of proteins: SH1 being the catalytic domain, SH2 being a phospho-tyrosine binding domain, and SH3 being a proline-binding domain. The Src SH2 domain binds to phospho-Tyr527 (phosphorylated by Csk) within the Src molecule, causing Src to adopt an inactive conformation. Mutation of Tyr527 to phenylalanine removes the SH2-binding target and results in a constitutively active kinase. A second mutation at the conserved lysine residue at the ATP-binding site abolishes kinase activity, but without Tyr527, the conformation of the protein is open, allowing interaction with endogenous activators. Consequently, this double-mutant exhibits a dominant-negative phenotype

Replaces: 05-889

Cultured supernantant containing 0.05% sodium azide.

Stable for 1 year at -20ºC from date of receipt.
Handling Recommendations: Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.

Control
Included positive antigen control of non-stimulated A431 lysate (Cat. No. 12-301). Add 2.5 μL of 2-mercaptoethanol/100 μL of lysate and boil for 5 minutes to reduce the preparation. Load 20 μg of reduced lysate per lane for minigels.

Western Blot Analysis: A 1:500 to 1:1000 dilution of this antibody detected Src in RIPA lysates from A431 cells.

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
