c-Src was the first proto-oncogenic non-receptor tyrosine kinase characterized in human. The Src family is composed of nine members in vertebrates, including c-Src, Yes, Fgr, Yrk, Fyn, Lyn, Hck, Lck, and Blk. Src-family kinases transduce signals that are involved in the control of a variety of cellular processes, including proliferation, differentiation, motility, and adhesion. Src-family kinases contain an N-terminal cell membrane anchor followed by SH3 and SH2 domains. The activity of Src family kinases is regulated by tyrosine phosphorylation at multiple sites. Phosphorylation of conserved N-terminal and central region tyrosine residues promotes activation, while phosphorylation of conserved C-terminal tyrosine residues downregulates Src kinase activity. Thus, tyrosine phosphorylation of Src kinases is critical for regulating their activity.

Western blot analysis of human A431 (lane 1) and Jurkat (lane 2) cell lysates, as well as adult mouse brain tissue (lane 3). The Blot was probed with mouse monoclonal anti-Yes (N-terminal region) at 1:1000.

Clone (M250) was generated from a recombinant protein containing amino acids in the N-terminal region of mouse Yes. This sequence has high homology to similar regions in rat and human Yes, but low homology to similar regions in other Src kinases.

Mouse monoclonal antibody purified with protein A chromatography is supplied in 100µl phosphate-buffered saline, 50% glycerol, 1 mg/ml BSA, and 0.05% sodium azide. Store at –20°C. Stable for 1 year.

The products are are safely shipped at ambient temperature for both domestic and international shipments. Each product is guaranteed to match the specifications as indicated on the corresponding technical data sheet. Please store at -20C upon arrival for long term storage.

The antibody detects a 59 kDa* protein corresponding to Yes on SDS-PAGE immunoblots of human A431 and Jurkat cells, as well as mouse brain. The antibody does not detect c-Src in mouse SYF cells transformed with c-Src.

*All molecular weights (MW) are confirmed by comparison to Bio-Rad Rainbow Markers and to western blot mobilities of known proteins with similar MW.
