Uniprot序列号：P08476, residues 311-426
纯度：＞98%（SDS-PAGE）
内毒素水平：Less than 1.0 EU/μg of Activin A as determined by the LAL method.
生物活性：The ED50 is less than 6 ng/ml as determined by its ability to inhibit the proliferation of mouse MPC-11 cells.
重溶：Centrifuge briefly and reconstitute Activin A in 10 mM HCl before dilution in cell culture medium. Avoid freeze-thaw cycles as it can result in loss of activity.
保存和稳定性：Activin A is shipped at room temperature. Lyophilized Activin A is stable for up to 6 months from date of receipt when stored at -20°C to -80°C. Reconstituted Activin A, at concentrations greater than 0.1 mg/ml, is stable for up to 3 months when stored at -20°C and for 1 year when stored at -80°C
