CST, 55225SF, Lck (73A5) Rabbit Monoclonal Antibody (BSA and Azide Free)

Monoclonal Antibody for studying Lck. Validated for Western Blotting. Highly specific and rigorously validated in-house, Lck (73A5) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #55225) is ready to ship. Product Usage Information This product is the carrier free version of product #2787. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol. This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN or CUT&Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us . Optimal dilutions/concentrations should be determined by the end user. BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity. Formulation Supplied in 1X PBS (10 mM Na 2 HPO 4 , 3 mM KCl, 2 mM KH 2 PO 4 , and 140 mM NaCl (pH 7.8)). BSA and Azide Free. For standard formulation of this product see product # 2787 Storage Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance. Specificity / Sensitivity Lck (73A5) Rabbit Monoclonal Antibody (BSA and Azide Free) detects endogenous levels of total Lck protein. Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Tyr505 of human Lck. Background The Src family of protein tyrosine kinases, which includes Src, Lyn, Fyn, Yes, Lck, Blk, and Hck, are important in the regulation of growth and differentiation of eukaryotic cells (1). Src activity is regulated by tyrosine phosphorylation at two sites, but with opposing effects. While phosphorylation at Tyr416 in the activation loop of the kinase domain upregulates enzyme activity, phosphorylation at Tyr530 in the carboxy-terminal tail by Csk renders the enzyme less active (2). p56lck (lymphocyte cellular kinase) has been shown to be a pivotal enzyme to both maturation of thymocytes and activation and proliferation of peripheral lymphocytes. The p56lck sequence appeared highly homologous to that of the oncogene p60c-src as did its exon-intron organisation. p56lck does not appear involved in lymphoproliferative diseases, either by overexpression or activating mutations. Nevertheless, its aberrant expression has been reported in some carcinomas (colon, lung and mammary). It was suggested that p56lck could favor metastases by facilitating loss of cell adhesion (3).
