免疫原
The antiserum was produced against synthesized peptide derived from N-ternal human CSK. AA range:31-80
特异性
Csk Polyclonal Antibody detects endogenous levels of Csk protein.
来源
Polyclonal, Rabbit,IgG
组成（Formulation）
Liquid in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide.
稀释比例
Western Blot: 1/500 - 1/2000. Immunofluorescence: 1/200 - 1/1000. ELISA: 1/5000. Not yet tested in other applications.
纯化工艺（Immunogen）
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen.
背景（Background）
catalytic activity:ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.,function:Specifically phosphorylates 'Tyr-504' on LCK, which acts as a negative regulatory site. Can also act on the LYN and FYN kinases.,PTM:Autophosphorylation of Tyr-304 occurs only at abnormally high CSK concentrations in vitro.,similarity:Belongs to the protein kinase superfamily. Tyr protein kinase family.,similarity:Belongs to the protein kinase superfamily. Tyr protein kinase family. CSK subfamily.,similarity:Contains 1 protein kinase domain.,similarity:Contains 1 SH2 domain.,similarity:Contains 1 SH3 domain.,subcellular location:Mainly cytoplasmic, also present in lipid rafts.,subunit:Interacts with PTPN8 (By similarity). Interacts with phosphorylated SIT1, PAG1, LIME1 and TGFB1I1.,tissue specificity:Expressed in lung and macrophages.,
