Recombinant streptococcal protein G lacking the albumin binding region thereby avoiding undesirable reactions with albumin, thoµgh the Fc binding domain is still present. The recombinant Protein G is produced in Escherichia coli using sequence from Streptococcus C1-C2-C3. The Protein G contains 196 amino acids (190-384) having a molecular mass of 21.6 kDa. The Protein-G migrates on SDS-PAGE around 32 kDa.

Lyophilized Recombinant Protein G althoµgh 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.
1. Binds with greater affinity to most mammalian immunoglobulins than Protein A, including human IgG3 and rat IgG2a. 2. Does not bind to human IgM, IgD and IgA.
