Description: Recombinant Human GDF2 Protein is produced by mammalian expression system and the target gene encoding Ser320-Arg429 is expressed with a 6His tag at the C-terminus. Form: Lyophilized from a 0.2 μM filtered solution of 4mM HCl. Gene Symbol: GDF2 Alternative Names: BMP9; Growth/differentiation factor 2; GDF-2; Bone morphogenetic protein 9; BMP-9Entrez Gene (Human): 2658SwissProt (Human): Q9UK05Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : SAGAGSHCQK TSLRVNFEDI GWDSWIIAPK EYEAYECKGG CFFPLADDVT PTKHAIVQTL VHLKFPTKVG KACCVPTKLS PISVLYKDDM GVPTLKYHYE GMSVAECGCR 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.
