Description

Description

Protein-A/G Recombinant produced in E.Coli is a single non-glycosylated polypeptide chain fused with a 6×His tag at C-terminus. Protein-A/G is comprised of 5 IgG-binding regions of protein A (E-D-A-B-C) and 3 of protein G (C1-C2-C3) containing 513 amino acids in total and having a molecular mass of 56.9kDa. Cell wall binding region, cell membrane binding region and albumin binding region have been eliminated from the recombinant Protein A/G to guarantee the maximum specific IgG binding.

Stability & Storage

Storage/Stability
Lyophilized Protein-A/G although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Protein-A/G should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).  Please prevent freeze-thaw cycles.
