- BP000174-CYT-078: Recombinant Human Activin-A, HEK-Active 
 
 Source: HEK-derived.
 The specific activity was determined by the dose-dependent inhibition of proliferation of the MPC-11 cell line (mouse plasmocytoma cell line) and is typically 0.5-5 ng/ml.
 Purity: > 95.0%, by SDS-PAGE.
- BP000174-CYT-146: Recombinant Mouse Activin-A 
 
 Source: E. coli-derived.
 Biological activity is assessed by the ability to induce cytoxicity of MPC-11 cells and was found to be 1-1.5 ng/ml corresponding to a specific activity of 666,667-1,000,000 Units/mg.
 Purity: > 95.0%, by SDS-PAGE.
