Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified B
The Src family of protein tyrosine kinases (including Src, Lyn, Fyn, Yes, Lck, Blk, Hck, etc.) are important in the regulation of growth and differentiation of eukaryotic cells (1). Src activity is regulated by tyrosine phosphorylation at two sites with opposing effects. Phosphorylation of Tyr416 in the activation loop of the kinase domain upregulates the enzyme; phosphorylation of Tyr527 in the C-terminal tail by Csk renders the enzyme less active (2). Lyn is a member of the Src family that is predominantly expressed in hematopoietic cells (3). Lyn participates in signaling from multiple cell surface receptors such as the B cell Ag receptor (BCR) and CD40 (4). Lck is essential for T-lymphocyte activation and differentiation (5,6). The activity of Lck is regulated by protein kinases and phosphatases. Phosphorylation of the C-terminal tyrosine 505 serves to downregulate Lck catalytic activity, while phosphorylation at tyrosine 394 leads to an increase in Lck activity (7).
Catalog #S6504-25A
ApplicationsSuitable for use in Western Blot. Other applications not tested.
Recommended DilutionWestern Blot: 1:1000.
Optimal dilutions to be determined by the researcher.
Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage, store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
Clone TypePolyclonal
ConcentrationNot determined
FormSupplied as liquid in 10mM HEPES, pH 7.5, 150mM sodium chloride, 0.1mg/ml BSA, 50% glycerol. No preservative added.
PurityPurified by Protein A chromatography and immunoaffinity chromatography.
ImmunogenSynthetic phosphopeptide corresponding to residues surrounding Tyr416 of human Src.
SpecificityRecognizes endogenous levels of human Src only when activated by phosphorylation at Tyr416. May crossreact with other Src family members (Lyn, Fyn, Lck, Yes and Hck) when phosphorylated at equivalent sites. Does not crossreact with Src phosphorylated at Tyr527. May corssreact with phosphorylated RTKs. Species Crossreactivity
