Human FST Protein
Recombinant of Human FST protein
Product Specifications
Product Name Alternative
FST, FS
Source
Escherichia Coli
Purity
Greater than 95.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Bioactivity
The activity is determined by the ability to neutralize ACTV inhibitory effect of mouse MPC-11 cells. The expected ED50 is 100-400ng/ml, corresponding to a Specific Activity of 2,500-10,000units/mg in the presence of 7.5ng/ml ACTV A.
Form
Sterile Filtered White lyophilized (freeze-dried) powder.
Solubility
It is recommended to reconstitute the lyophilized Follistatin in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions.
Storage Conditions
Stability: Lyophilized Follistatin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FST should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA) .Please prevent freeze-thaw cycles
Notes
For research use only.
Applications Notes
Cytokines And Growth Factors
Preservative
Lyophilized from a concentrated (1mg/ml) solution containing no additives.
AA Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Gly-Asn-Cys-Trp-Leu
