>Human Latent Activin A / INHBA Protein,His Tag
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 13 kDa (mature) & 32 kDa (pro). As a result of glycosylation and Interchain disulfide bond, 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).
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.
For long term storage, the product should be stored at lyophilized state at -20°C or lower.
Please avoid repeated freeze-thaw cycles.
No activity loss is observed after storage at:
Human Latent Activin A, His Tag on SDS-PAGE under reducing (R) and no-reducing (NR) conditions. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.
The bio-activity of latent Activin A（Cat. No. ACA-H424x）was determined by dose-dependent inhibition of the proliferation of MPC-11 cells. The EC50 for this effect is typically 47-66ng/mL (Routinely tested).
