Molecular Biology Storage: 4°CShipping: RT
Protein G originated from Streptococci is a monomeric protein with a molecular weight of about 50,000kD. Protein G binds with high affinity to the Fc region of most classes and subclasses of immunoglobulins from mouse, rabbit, goat and human. Due to this binding ability, Protein G is commonly used in the purification and recovery of either polyclonal or monoclonal immunoglobulins. Recombinant Protein G used in Protein G beads is a genetically engineered form of Protein G. Non-essential regions have been removed while leaving the IgG binding sites intact. The recombinant Protein G has been immobilized on Sepharose beads in order to create a versatile product for both the purification of various mammalian immunoglobulins and for isolating immune complexes by immunoprecipitation (IP).
