Description: Recombinant Human TNFRSF1B Protein is produced by mammalian expression system and the target gene encoding Lys288-Ser461 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: TNFRSF1B Alternative Names: TNFBR; TNFR2; Tumor necrosis factor receptor superfamily member 1B; Tumor necrosis factor receptor 2; TNF-R2; Tumor necrosis factor receptor type II; TNF-RII; TNFR-II; p75; p80 TNF-alpha receptor; CD120b; EtanerceptEntrez Gene (Human): 7133SwissProt (Human): P20333Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : KKKPLCLQRE AKVPHLPADK ARGTQGPEQQ HLLITAPSSS SSSLESSASA LDRRAPTRNQ PQAPGVEASG AGEARASTGS SDSSPGGHGT QVNVTCIVNV CSSSDHSSQC SSQASSTMGD TDSSPSESPK DEQVPFSKEE CAFRSQLETP ETLLGSTEEK PLPLGVPDAG MKPSVDHHHH HH 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.
