Description：Recombinant Human ESR2 Protein is produced by E. coli expression system and the target gene encoding Met1-Ala323 is expressed with a 6His tag at the N-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 50mM Tris-HCl, pH 8.0.Gene Symbol：ESR2Alternative Names：ESTRB; NR3A2; Estrogen receptor beta; ER-beta; Nuclear receptor subfamily 3 group A member 2 Entrez Gene (Human)： 2100; SwissProt (Human)： Q92731; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MGSSHHHHHH SSGLVPRGSH MDIKNSPSSL NSPSSYNCSQ SILPLEHGSI YIPSSYVDSH HEYPAMTFYS PAVMNYSIPS NVTNLEGGPG RQTTSPNVLW PTPGHLSPLV VHRQLSHLYA EPQKSPWCEA RSLEHTLPVN RETLKRKVSG NRCASPVTGP GSKRDAHFCA VCSDYASGYH YGVWSCEGCK AFFKRSIQGH NDYICPATNQ CTIDKNRRKS CQACRLRKCY EVGMVKCGSR RERCGYRLVR RQRSADEQLH CAGKAKRSGG HAPRVRELLL DALSPEQLVL TLLEAEPPHV LISRPSAPFT EASMMMSLTK LADKELVHMI SWAKKIPGMR GNADirections 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.
