Description：Recombinant Human YY1 Protein is produced by E. coli expression system and the target gene encoding Val221-Gly321 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：YY1Alternative Names：INO80S; Transcriptional repressor protein YY1; Delta transcription factor; INO80 complex subunit S; NF-E1; Yin and yang 1; YY-1 Entrez Gene (Human)： 7528; SwissProt (Human)： P25490; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MVTMWSSDEK KDIDHETVVE EQIIGENSPP DYSEYMTGKK LPPGGIPGID LSDPKQLAEF ARMKPRKIKE DDAPRTIACP HKGCTKMFRD NSAMRKHLHT HGLEHHHHHHDirections 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.
