Purification of streptococcal protein G expressed by Escherichia coli by high performance liquid affinity chromatography using immobilized immunoglobulin G and albumin
A one-step HPLC method was developed for the purification of protein G, a cell wall molecule from group C and G streptococci with immunoglobulin G- and albumin-binding properties. Lysed Escherichia coli bacteria infected with lambda-phages containing the protein G gene from group G streptococci were used as a starting material for the preparations. The lysate was applied to a column with immobiliz
