表达区间及表达系统（Source）

Human Erythropoietin R & CD131 Protein, Fc Tag&Fc Tag (ERR-H5255) is expressed from human 293 cells (HEK293). It contains AA Ala 25 - Pro 250 & Trp 17 - Trp 443 (Accession # P19235-1 & P32927-1).

Predicted N-terminus: Ala 25 & Trp 17

蛋白结构（Molecular Characterization）

Human Erythropoietin R & CD131 Protein, Fc Tag&Fc Tag is produced by co-expression of Erythropoietin R and CD131, has a calculated MW of 51.3 kDa (Erythropoietin R) & 74.9 kDa (CD131). Subunit Erythropoietin R is fused with a human IgG1 Fc tag at the C-terminus and subunit CD131 is fused with a human IgG1 Fc tag at the C-terminus. The protein migrates as 55-60 kDa and 80-95 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

The protein is designed as a heterodimer.
