Human CTLA-4 / CD152 Protein, His Tag

  • Synonym
    CTLA4,CD152
  • Source
    Human CTLA-4, His Tag (CT4-H5229) is expressed from human 293 cells (HEK293). It contains AA Ala 37 - Phe 162 (Accession # P16410-1).
    Predicted N-terminus: Ala 37
  • Molecular Characterization
    Online(Ala 37 - Phe 162) P16410-1

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

    The protein has a calculated MW of 15.4 kDa. The protein migrates as 20-25 kDa under reducing (R) condition (SDS-PAGE) due to different extent 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 PBS, pH7.4. 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.

    This product is stable after storage at:

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 6 months under sterile conditions after reconstitution.
