Description: Recombinant Human FSHB Protein is produced by mammalian expression system and the target gene encoding Asn19-Glu129 is expressed with a 6His tag at the C-terminus. Form: Lyophilized from a 0.2 μM filtered solution of PBS, pH 7.4. Gene Symbol: FSHB Alternative Names: Follitropin subunit beta; Follicle-stimulating hormone beta subunit; FSH-B; FSH-beta; Follitropin beta chainEntrez Gene (Human): 2488SwissProt (Human): P01225Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : NSCELTNITI AIEKEECRFC ISINTTWCAG YCYTRDLVYK DPARPKIQKT CTFKELVYET VRVPGCAHHA DSLYTYPVAT QCHCGKCDSD STDCTVRGLG PSYCSFGEMK EVDHHHHHH Directions for Use : Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Quality Control : Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.Storage/Stability : Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months.
