    Product Information

    Product Description

    This Cell Signaling Technology® antibody is the biotinylated version of the unconjugated Itk (2F12) Mouse Monoclonal Antibody #2380 and is expected to exhibit the same species cross-reactivity. The concentration of the biotinylated antibody is 500 ug/ml. Peptide ELISA data were generated using the biotinylated antibody. Western blot data were generated using the unconjugated antibody.
    MW (kDa) 72

    Product Usage Information

    Biotinylated antibodies are ideal for immunoassay technologies and high-throughput ELISA platforms that require antibody pairs where both antibodies are from the same host. Platforms utilizing biotinylated antibodies include, but are not limited to, MSD, xMAP, Quanterix Simoa, AlphaLISA, AlphaScreen, HTRF, LANCE, and TR-FRET.

    Optimal dilutions/working concentrations should be determined by the end user. Please contact us if you require the antibody clone biotinylated at a different concentration, a carrier-free formulation, or a more customized packaging solution.

    Storage

    Supplied in 140 mM NaCl, 3 mM KCl, 10 mM sodium phosphate (pH 7.4) dibasic, 2 mM potassium phosphate monobasic, 2 mg/mL BSA, and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human Itk protein.

    Background

    Interleukin-2 inducible T cell kinase (Itk, Emt, or Tsk) is a member of the non-receptor protein tyrosine kinases. Family members of Itk include Tec, Btk, Rlk, and Bmx and are all defined by a common structure: an amino-terminal PH domain, a Tec-homology domain, and an SH3 and SH2 domain followed by a carboxy-terminal kinase domain (1). Tec, Rlk, and Itk are expressed in T cells and activated in response to T cell receptor (TCR) engagement. Data demonstrate that Itk functions in signal transduction downstream of TCR and activates PLCgamma1 and Erk. Lck directly activates Itk through phosphorylation in the conserved activation loop at Tyr511, and furthermore, Itk is autophosphorylated in the SH3 domain at Tyr180. Itk-Y180F is still capable of phosphorylating PLCgamma1 in contrast to Itk-Y511F, which has lost that function (2-3). Itk -/- mice show reduced lung inflammation, eosinophil infiltration, and mucous production in response to allergic asthma induction. Thus, Itk could become a desirable target for anti-asthmatic treatments (4).
