Activation of B cells by various ligands is accompanied by activation of Blk. It has been suggested that Blk is involved in the control of B cell differentiation and proliferation. Blk transcripts have also been detected in human thymocytes, but not in mature T cells, implicating that Blk may play an important role in thymopoiesis. Blk function may be redundant, however, as mice that do not express Blk are not impaired with respect to B cell development and immune response.\u003c\/p\u003e\n\n\u003cp\u003eCategory: Primary Antibody\u003c\/p\u003e\n\n\u003cp\u003eReactivity: Human, Mouse, Rat\u003c\/p\u003e\n\n\u003cp\u003eHost: Rabbit\u003c\/p\u003e\n\n\u003cp\u003eApplications: WB\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: Tyrosine-protein kinase Blk, B lymphocyte kinase, p55-Blk, BLK\u003c\/p\u003e\n\n\u003cp\u003eClonality: Polyclonal\u003c\/p\u003e\n\n\u003cp\u003eConjugate: Unconjugated\u003c\/p\u003e\n\n\u003cp\u003eModification: Phosphorylation\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: Synthetic phosphopeptide derived from human BLK around the phosphorylation site of Tyrosine389.\u003c\/p\u003e\n\n\u003cp\u003eDilution: WB: 1:500~1:1000\u003c\/p\u003e\n\n\n\u003cp\u003ePurification: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is \u0026gt; 95% (by SDS-PAGE).\u003c\/p\u003e\n\n\u003cp\u003eSpecificity: BLK (phospho-Y389) polyclonal antibody detects endogenous levels of BLK protein only when phosphorylated at Tyr389 .\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight: ~ 57 kDa\u003c\/p\u003e\n\n\u003cp\u003eStorage and Stability: Store at 4°C short term.
