Description：Recombinant Human CTCF Protein is produced by E. coli expression system and the target gene encoding Met1-Ile154 is expressed.Form：Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.4.Gene Symbol：CTCFAlternative Names：Transcriptional repressor CTCF; 11-zinc finger protein; CCCTC-binding factor; CTCFL paralog Entrez Gene (Human)： 10664; SwissProt (Human)： P49711; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MEGDAVEAIV EESETFIKGK ERKTYQRRRE GGQEEDACHL PQNQTDGGEV VQDVNSSVQM VMMEQLDPTL LQMKTEVMEG TVAPEAEAAV DDTQIITLQV VNMEEQPINI GELQLVQVPV PVTVPVATTS VEELQGAYEN EVSKEGLAES EPMIDirections 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.
