Description: FSH Human Recombinant produced in HEK-293 cells is heterodimeric, glycosylated, polypeptide chain transfected with two expression plasmids encoding the human FSH-alpha chain (Accession # P01215) (Ala25-Ser116) and human FSH-beta chain (Asn19-Glu129) (Accession # P01225) having a total Mw of 38kDa. FSH human recombinant is purified by proprietary chromatographic techniques.
Protein Derived From: HEK293
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
Purity: Greater than 95% as determined by SDS-PAGE.
Stability: Lyophilized recombinant FSH although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FSH 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.
Biological Activity: The ED50 as determined by cAMP accumulation in human FSH Receptor transfected Chinese Hamster Ovary cells was found to be 80-450 pg/ml.
Solubility: It is recommended to reconstitute the lyophilized Follicle Stimulating Hormone in sterile 18MOmegacm H2O not less than 100 microg/ml, which can then be further diluted to other aqueous solutions.
