Immunogen
The antiserum was produced against synthesized peptide derived from human HS1 around the phosphorylation site of Tyr397. AA range:366-415
Specificity
Phospho-Lck BP-1 (Y397) Polyclonal Antibody detects endogenous levels of Lck BP-1 protein only when phosphorylated at Y397.
Formulation
Liquid in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide.
Dilution rate
WB 1:500-2000;IHC-p 1:50-300
Purification process (Immunogen)
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen.
Background
developmental stage:Expressed in early stage of myeloid and erythroid differentiation.,function:Substrate of the antigen receptor-coupled tyrosine kinase. Plays a role in antigen receptor signaling for both clonal expansion and deletion in lymphoid cells. May also be involved in the regulation of gene expression.,PTM:Phosphorylated by LYN; rapidly after cross-linking of surface IgM on B-cells.,similarity:Contains 1 SH3 domain.,similarity:Contains 4 cortactin repeats.,subunit:Associates with the SH2 and SH3 domains of LCK. Binding to he LCK SH3 domain occurs constitutively, while binding to the LCK SH2 domain occurs only upon TCR stimulation. A similar binding pattern was observed with LYN, but not with FYN in which the FYN SH2 region associates upon TCR stimulation but the FYN SH3 region does not associate regardless of TCR stimulation. Directly associates with HAX1, through binding to its C-terminal region. Interacts with HS1BP3.,tissue specificity:Expressed only in tissues and cells of hematopoietic origin.,
