|Product Overview:||Recombinant Human INHBA, Gly311-Ser426, was produced in CHO cell under cGMP guidelines.|
|Form:||Lyophilized from a 0.2 μm filtered solution in Acetonitrile and TFA.|
|Bio-activity:||Measured by its ability to induce hemoglobin expression in K562 human chronic myelogenous leukemia cells. Schwall, R.H. et al. (1991) Method Enzymol. 198:340. The ED50 for this effect is 0.2-1.2 ng/mL.
The specific activity of Recombinant Human/Mouse/Rat Activin A is approximately 1 IU/μg, which is calibrated against human Activin A WHO International Standard (NIBSC code: 91/626).
