Cat#:RP-5242H;Product Name:Recombinant Human Protein-G His;Description:Protein G His Tag Recombinant produced in E.coli is a 201 amino acids protein which contains amino acid 190-384 of the Streptococcus sp with a C-terminal 6-His tag, and having a molecular mass of 21.6kDa. But it migrates with an apparent molecular mass of 32kDa in SDS-PAGE. The Protein G His Tag is purified by proprietary chromatographic techniques.;Source:E.coli;Purity:Greater than 95.0% as determined by SDS-PAGE and HPLC analyses.;Formulation:Lyophilized with no additives.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized Protein G in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized Protein G although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Protein G should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles.;
