IL12, p70, Interleukin-12

Human IL-12B&IL-12A Heterodimer Protein, His Tag&Flag Tag is produced by co-expression of IL-12B and IL-12A, has a calculated MW of 36.6 kDa (IL-12B) and 23.8 kDa (IL-12A). Subunit IL-12B is fused with polyhistidine tag at the C-terminus and subunit IL-12A is fused with flag tag at the C-terminus. The protein migrates as 30-38 kDa (IL12B) and 40-50 kDa (IL12A) 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.
Less than 0.01 EU per μg by the LAL method / rFC method.
>90% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
