Human IL-17A & IL-17F Heterodimer Protein, produced by co-expression of IL-17A and IL-17F, has a calculated MW of 17.0 kDa (IL-17A) and 18.4 kDa (IL-17F). Subunit IL-17A is fused with a polyhistidine tag at the N-terminus and subunit IL-17F is fused with a Twin Strep tag at the N-terminus. The predicted N-terminus is His (IL-17A) & Ser (IL-17F). The reducing (R) protein migrates as 19 kDa (IL-17A) and 21 kDa (IL-17F) respectively due to glycosylation.
>95% as determined by reduced SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
