Our Abpromise guarantee covers the use of ab155100 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB 1/1000 - 1/10000. Predicted molecular weight: 47 kDa.

Csk binding protein is an ubiquitously expressed 47 kDa transmembrane adaptor protein present in membrane microdomains (rafts), which however migrates on SDS-PAGE gels anomalously as an 80 kDa molecule. PAG has a pI value of about 4.6 and binds poorly to SDS and therefore has decreased mobility on SDS gels.

IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol. (Heat to 98°C, allow to cool for 10-20 minutes)
IP 1/10 - 1/100.
Flow Cyt 1/100 - 1/500.

ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.

  • Application notes
    Is unsuitable for ICC.
  • Target

    • Function
      Negatively regulates TCR (T-cell antigen receptor)-mediated signaling in T-cells and FCER1 (high affinity immunoglobulin epsilon receptor)-mediated signaling in mast cells. Promotes CSK activation and recruitment to lipid rafts, which results in LCK inhibition. Inhibits immunological synapse formation by preventing dynamic arrangement of lipid raft proteins. May be involved in cell adhesion signaling.
    • Tissue specificity
      Ubiquitously expressed. Present in germinal center B-cells, plasma cells, T-cells, monocytes and platelets (at protein level).
    • Post-translational
      Phosphorylated by FYN on Tyr-317 in resting T-cells; which promotes interaction with CSK. Dephosphorylated by PTPRC/CD45 upon TCR activation; which leads to CSK dissociation. May also be dephosphorylated by PTPN11. Hyperphosphorylated in mast cells upon FCER1 activation.
    • Cellular localization
      Cell membrane. Present in lipid rafts.
