Human COMP / TSP5 Protein

  • Synonym
  • Source
    Human COMP, His Tag (COP-H5220) is expressed from human 293 cells (HEK293). It contains AA Gln 21 - Ala 757 (Accession # AAI25093).
    Predicted N-terminus: Gln 21
  • Molecular Characterization
    COMP(Gln 21 - Ala 757) AAI25093

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

    The protein has a calculated MW of 82 kDa. The protein migrates as 110-130 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

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

    >88% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

  • 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.
