Human Carboxypeptidase A4 / CPA4 Protein

  • Synonym
    CPA4,Carboxypeptidase A4,CPA3
  • Source
    Human Carboxypeptidase A4, His Tag (CP4-H5222) is expressed from human 293 cells (HEK293). It contains AA Gly 17 - Tyr 421 (Accession # AAH52289).
    Predicted N-terminus: Gly 17
  • Molecular Characterization
    CPA4(Gly 17 - Tyr 421) AAH52289

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 46.4 kDa. The protein migrates as 48 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH 7.5. Normally trehalose is added as protectant before lyophilization.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

    No activity loss is observed after storage at:

    1. 4-8°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
