Description：Recombinant Mouse IgG2B Fc Protein is produced by mammalian expression system and the target gene encoding Glu97-Lys335 is expressedForm：Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH7.4.Gene Symbol：IGH-3Alternative Names：Ig gamma-2B chain C region; Igh-3 Entrez Gene (Mouse)： 16016; SwissProt (Mouse)： P01867; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MSSSVTVPSS TWPSQTVTCS VAHPASSTTV DKKLEPSGPI STINPCPPCK ECHKCPAPNL EGGPSVFIFP PNIKDVLMIS LTPKVTCVVV DVSEDDPDVR ISWFVNNVEV HTAQTQTHRE DYNSTIRVVS ALPIQHQDWM SGKEFKCKVN NKDLPSPIER TISKIKGLVR APQVYILPPP AEQLSRKDVS LTCLVVGFNP GDISVEWTSN GHTEENYKDT APVLDSDGSY FIYSKLDIKT SKWEKTDSFS CNVRHEGLKN YYLKKTISRS PGKDirections 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.
