Human IL-23A&Rat IL-12B Heterodimer Protein, His Tag&Tag Free, produced by co-expression of IL23A and IL12B, has a calculated MW of 20.6 kDa (IL23A) and 35.9 kDa (IL12B). Subunit IL-23A is fused with a polyhistidine tag at the N-terminus and subunit IL-12B contains no tag. The protein migrates as 23-25 kDa,43 kDa and 45 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
