Rat FcRn/FCGRT & B2M Heterodimer Protein

  • Synonym
    FcRn,FCGRT & B2M
  • Source
    Rat FcRn / FCGRT & B2M Heterodimer Protein, Ala 23 - Ser 298 (FCGRT, NP_203502.1) and & Ile 21 - Met 119 (B2M, NP_036644), was produced in human 293 cells (HEK293) at ACRObiosystems.
    Predicted N-terminus: Ala 23 (FCGRT) & Ile 21 (B2M)
  • Molecular Characterization
    FcRn(Ala 23 - Ser 298 (FCGRT) & Ile 21 - Met 119 (B2M)) NP_203502.1 (FCGRT) & NP_036644 (B2M)

    Rat FcRn / FCGRT & B2M Heterodimer Protein, produced by co-expression of FCGRT and B2M, has a calculated MW of 31.8 kDa (FCGRT) and 13.1 kDa (B2M). Subunit FCGRT is fused with his-tag at the C-terminus and subunit Beta-2 microglobulin (B2M) is fused with Strep II-tag at the C-terminus. The predicted N-terminus is Ala 23 (FCGRT) & Ile 21 (B2M). The reducing (R) protein migrates as 45-50 kDa (FCGRT) and 14.5 kDa (B2M) respectively due to different 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.

    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.
SDS-PAGE
