CERTIFICATE OF ANALYSIS AND DATA SHEET

PRODUCT DESCRIPTION:
Recombinant Human Follistatin produced in E.Coli is a single, non-glycosylated polypeptide chain containing 288 amino acids and having a total molecular mass of 31.5kDa. The rHuFST is purified by proprietary chromatographic techniques

SOURCE: Insect Cell

FORMULATION:
Lyophilized from a concentrated (1mg/ml) solution containing 10mM Sodium Phosphate buffer and 75 mM Sodium Chloride.

PURITY:
Greater than 95.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE

STORAGE:
Although stable at room temperature for 3 weeks, it should be stored desiccated below -18°C. Upon reconstitution it should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles.

SOLUBILITY:
It is recommended to reconstitute in sterile H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

BIOLOGICAL ACTIVITY: rhFollistatin is fully biologically active when compared to standard. The activity is determined by the ability to neutralize Activin A inhibitory effect of mouse MPC-11 cells. The expected ED50 is 0.1-0.4 ug/ml in the presence of 7.5 ng/ml Activin A.

ENDOTOXIN: Less than 0.1 ng/ug (IEU/ug)
