Description: Recombinant Human GDF11 Protein is produced by mammalian expression system and the target gene encoding Asn299-Ser407 is expressed. Form: Lyophilized from a 0.2 μM filtered solution of PBS, pH 7.4. Gene Symbol: GDF11 Alternative Names: BMP11; Growth/differentiation factor 11; GDF-11; Bone morphogenetic protein 11; BMP-11Entrez Gene (Human): 10220SwissProt (Human): O95390Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : NLGLDCDEHS SESRCCRYPL TVDFEAFGWD WIIAPKRYKA NYCSGQCEYM FMQKYPHTHL VQQANPRGSA GPCCTPTKMS PINMLYFNDK QQIIYGKIPG MVVDRCGCS 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.
