Description：Recombinant Human SIT1 Protein is produced by E. coli expression system and the target gene encoding Gln65-Ser196 is expressed with a 6His tag at the N-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 20mM Tris, 250mM Nacl, 2mM EDTA, pH 8.0.Gene Symbol：SIT1Alternative Names：SIT; Signaling threshold-regulating transmembrane adapter 1; SHP2-interacting transmembrane adapter protein; Suppression-inducing transmembrane adapter 1; gp30/40 Entrez Gene (Human)： 27240; SwissProt (Human)： Q9Y3P8; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MGSSHHHHHH SSGLVPRGSH MQWTRGRSRS HPGQGRSGES VEEVPLYGNL HYLQTGRLSQ DPEPDQQDPT LGGPARAAEE VMCYTSLQLR PPQGRIPGPG TPVKYSEVVL DSEPKSQASG PEPELYASVC AQTRRARASF PDQAYANSQP AASLEHHHHH HDirections 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.
