Description：Recombinant Human HBEGF Protein is produced by mammalian expression system and the target gene encoding Leu20-Leu148 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.Gene Symbol：HBEGFAlternative Names：DTR; DTS; HEGFL; Proheparin-binding EGF-like growth factor Entrez Gene (Human)： 1839; SwissProt (Human)： Q99075; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：LVTGESLERL RRGLAAGTSN PDPPTVSTDQ LLPLGGGRDR KVRDLQEADL DLLRVTLSSK PQALATPNKE EHGKRKKKGK GLGKKRDPCL RKYKDFCIHG ECKYVKELRA PSCICHPGYH GERCHGLSLH HHHHHDirections 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 ddH4O. 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.
