Description：Recombinant Human TNFRSF11B Protein is produced by mammalian expression system and the target gene encoding Glu22-Leu401 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.4.Gene Symbol：TNFRSF11BAlternative Names：OCIF; OPG; Tumor necrosis factor receptor superfamily member 11B; Osteoclastogenesis inhibitory factor; Osteoprotegerin Entrez Gene (Human)： 4982; SwissProt (Human)： O00300; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：ETFPPKYLHY DEETSHQLLC DKCPPGTYLK QHCTAKWKTV CAPCPDHYYT DSWHTSDECL YCSPVCKELQ YVKQECNRTH NRVCECKEGR YLEIEFCLKH RSCPPGFGVV QAGTPERNTV CKRCPDGFFS NETSSKAPCR KHTNCSVFGL LLTQKGNATH DNICSGNSES TQKCGIDVTL CEEAFFRFAV PTKFTPNWLS VLVDNLPGTK VNAESVERIK RQHSSQEQTF QLLKLWKHQN KDQDIVKKII QDIDLCENSV QRHIGHANLT FEQLRSLMES LPGKKVGAED IEKTIKACKP SDQILKLLSL WRIKNGDQDT LKGLMHALKH SKTYHFPKTV TQSLKKTIRF LHSFTMYKLY QKLFLEMIGN QVQSVKISCL VDHHHHHHDirections 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.
