Description：Recombinant Human SHH Protein is produced by E.coli expression system and the target gene encoding Cys24-Gly197 (Cys24Ile-Ile) is expressed.Form：Lyophilized from a 0.2 μm filtered solution of 20mM PB, 100mM NaCl, 1mM DTT, pH 7.5.Gene Symbol：SHHAlternative Names：Sonic hedgehog protein; SHH; HHG-1 Entrez Gene (Human)： 6469; SwissProt (Human)： Q15465; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MIIGPGRGFG KRRHPKKLTP LAYKQFIPNV AEKTLGASGR YEGKISRNSE RFKELTPNYN PDIIFKDEEN TGADRLMTQR CKDKLNALAI SVMNQWPGVK LRVTEGWDED GHHSEESLHY EGRAVDITTS DRDRSKYGML ARLAVEAGFD WVYYESKAHI HCSVKAENSV AAKSGGDirections 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 ddH2O. 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.
