This protein carries a polyhistidine tag at the N-terminus
The protein has a calculated MW of 13.0 kDa (mature) and 32.0 kDa (pro). The protein migrates as 15 kDa (mature) and 43-48 kDa (pro) under reducing (R) condition, and 27 kDa (mature), 43-48 kDa (pro) and 60 kDa (pro & mature) under non-reducing (NR) condition (SDS-PAGE) due to glycosylation and Interchain disulfide bond.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

This product is stable after storage at:
Human Latent Activin A, His Tag on SDS-PAGE under reducing (R) and non-reducing (NR) conditions. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.
Immobilized Human Latent Activin A, His Tag (Cat. No. ACA-H424x) at 10 μg/mL (100 μL/well) can bind Human ACVR2A, Fc Tag (Cat. No. ACA-H5269) with a linear range of 0.6-20 ng/mL (QC tested).
The bio-activity of Human Latent Activin A, His Tag (Cat. No. ACA-H424x) was determined by dose-dependent inhibition of the proliferation of MPC-11 cells. The EC50 for this effect is typically 47-66 ng/mL (Routinely tested).
