Description: Recombinant Human SFN Protein is produced by E. coli expression system and the target gene encoding Met1-Ser248 is expressed. Form: Lyophilized from a 0.2 μM filtered solution of 20mM PB, 250mM NaCl, 1mM EDTA, 1mM DTT, pH 7.4. Gene Symbol: SFN Alternative Names: HME1; 14-3-3 protein sigma; Epithelial cell marker protein 1; StratifinEntrez Gene (Human): 2810SwissProt (Human): P31947Purity : Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure : MERASLIQKA KLAEQAERYE DMAAFMKGAV EKGEELSCEE RNLLSVAYKN VVGGQRAAWR VLSSIEQKSN EEGSEEKGPE VREYREKVET ELQGVCDTVL GLLDSHLIKE AGDAESRVFY LKMKGDYYRY LAEVATGDDK KRIIDSARSA YQEAMDISKK EMPPTNPIRL GLALNFSVFH YEIANSPEEA ISLAKTTFDE AMADLHTLSE DSYKDSTLIM QLLRDNLTLW TADNAGEEGG EAPQEPQS 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.
