The Protein G is a single, non-glycosylated protein contains 200 amino acids having a molecular mass of 21.8kDa. The Protein-G migrates on SDS-PAGE around 32kDa.
Escherichia Coli.
Sterile Filtered White lyophilized (freeze-dried) powder.
Lyophilized white powder containing no additives.
Reconstitution with deionized water or PBS.
Lyophilized Recombinant 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.
>96% as determined by SDS-PAGE and RP-HPLC.
