Recombinant Human FSHB Protein (Met1-Glu129), HIgG1 Fc-tagged

Specification :
| Description : Follicle-stimulating hormone (FSH) is a gonadotrope-derived heterodimeric glycoprotein. FSH plays an essential role in processes involved in human reproduction, including spermatogenesis and the ovarian cycle. FSHB represents a conservative vertebrate gene with a unique function and it is located in a structurally stable gene-poor region. Polymorphisms in the follicle stimulating hormone beta subunit (FSHB) and follicle stimulating hormone receptor (FSHR) genes might disturb normal spermatogenesis and affect male reproductive ability. The FSHB -211G>T genotype is a key determinant in the regulation of gonadotropins in different reproductive-endocrine pathopyhsiologies. | Source : HEK293 | Species : Human | Tag : HIgG1 Fc | Predicted N Terminal : Asn 19 | Form : Lyophilized from sterile PBS, pH 7.4. Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. | Molecular Mass : The recombinant human FSHB consists of 349 amino acids and predicts a molecular mass of 39.2 kDa. | Protein length : Met1-Glu129 | Endotoxin : | Purity : > 95 % as determined by SDS-PAGE. | Stability : Samples are stable for up to twelve months from date of receipt at -70 centigrade. | Storage : Store it under sterile conditions at -20 centigrade to -80 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4℃ before opening to recover the entire contents. | Shipping : In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
