Description：Recombinant Human TGF beta 1 Protein is produced by mammalian expression system and the target gene encoding Leu30-Ser390 is expressedForm：Lyophilized from a 0.2 μm filtered solution of 50mM Glycine, 50mM NaCl, pH4.0.Gene Symbol：TGFB1Alternative Names：TGFB; Transforming growth factor beta-1; TGF-beta-1 Entrez Gene (Human)： 7040; SwissProt (Human)： P01137; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：HHHHHHHHLS TSKTIDMELV KRKRIEAIRG QILSKLRLAS PPSQGEVPPG PLPEAVLALY NSTRDRVAGE SAEPEPEPEA DYYAKEVTRV LMVETHNEIY DKFKQSTHSI YMFFNTSELR EAVPEPVLLS RAELRLLRLK LKVEQHVELY QKYSNNSWRY LSNRLLAPSD SPEWLSFDVT GVVRQWLSRG GEIEGFRLSA HCSCDSRDNT LQVDINGFTT GRRGDLATIH GMNRPFLLLM ATPLERAQHL QSSRHRRALD TNYCFSSTEK NCCVRQLYID FRKDLGWKWI HEPKGYHANF CLGPCPYIWS LDTQYSKVLA LYNQHNPGAS AAPCCVPQAL EPLPIVYYVG RKPKVEQLSN MIVRSCKCSDirections 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 ddH2O. 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.
