Our Abpromise guarantee covers the use of ab9527 in the following tested applications.

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

应用 Ab评论 说明
  • 应用说明WB: Use at an assay dependant dilution. Use a lysis buffer made with Tris HCl (pH 8.1) and 1%laurylmaltoside (with common protease inhibitors). Use under non-reducing conditions.
    Csk binding protein is an ubiquitously expressed 46 kDa transmembrane adaptor protein present in membrane microdomains (rafts), which however migrates on SDS-PAGE gels anomalously as an 80 kDa molecule. The reason is, that PAG has a pI value of about 4.6 and binds poorely SDS and therefore it had decreased mobility on SDS gels.

    Is unsuitable for IP (use ab4206 or ab14989).

    May be unsuitable for ICC-IF due to unsuccesful results in submitted Abreview. (Please see Abreview comments)

    Not tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • 靶标

    • 功能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.
    • 组织特异性Ubiquitously expressed. Present in germinal center B-cells, plasma cells, T-cells, monocytes and platelets (at protein level).
    • 翻译后修饰Palmitoylated.
      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.
    • 细胞定位Cell membrane. Present in lipid rafts.

    Thank you for your enquiry. CSK Binding Protein antibody Ref:ab9527 [MEM-255] should stain blots strongly in dilutions 1:500 - 1:1000 but optimum dilution should be done for a particular system of a researcher. We did not measure protein load, it alway...
