Introduction:

Rat-PA is improved in binding specificity for Fc region as well as protein stability and alkali tolerant by residue substitution compared to protein A. It is immobilized onto solid matirx such as agarose beads for IgG purification from ascitic fluid, serum, culture supernatants, cell extracts or interested proteins. For efficient covalently conjugation to resin, one cysteine residue is inserted at the C-terminus of rat-PA.
