Protein G has high affinity regions that are specially bonded to the Fc region of the immunoglobulins (especially IgGs of different species). Protein G agarose beads is ideal for polyclonal IgG purification from mouse, human, goat, sheep serum, including human IgG3 and mouse IgG1 iso-types.
Protein G PLUS Agarose resin consists of Recombinant Protein G (≥ 5 mg Protein G / ml resin) covalently coupled to cross-linked activated agarose beads. It provides a very stable bond that can greatly minimize leakage of the Protein G allowing for reuse of the affinity resin in several purification steps. The resin works well in batch or column purifications. The product is also suitable for immunoprecipitation (IP) procedures.
This product is supplied as 50% suspension of Protein G Agarose Resin in 20% ethanol. The settled bead volume is as per each product pack.
The product should never be Frozen and storage temperature is 4°C.
