A method for purifying a protein comprising an antibody, antibody fragment, or immunoglobulin single variable domain, from a solution containing at least one contaminant by superantigen chromatography comprising: a) adsorbing the protein to the superantigen immobilized on a solid support; b) removing the at least one contaminant by contacting the immobilized superantigen containing the adsorbed protein with a first wash buffer comprising an aliphatic carboxylate; and c) eluting the protein from the superantigen immobilized on the solid support.

Methods for purifying antibodies

The present invention relates to a method of purifying a recombinant polypeptide from Host Cell Proteins (HCP), the method comprising: (a) applying a solution comprising the recombinant polypeptide and HCP to a superantigen chromatography solid support, (b) washing the superantigen chromatography solid support with a wash buffer comprising caprylate and arginine; and (c) eluting the recombinant polypeptide from the superantigen chromatography solid support.

A method for purifying a protein using a simplified, sodium chloride-free buffer system that consists of two components (acid and base pairs) for appropriate solution pH control; and a third component for ionic strength control, where the third component is the sodium salt conjugate base.

Buffer system for protein purification

The invention is directed to a method for producing a polypeptide composition comprising: combining a polypeptide with a volatile additive to form a liquid mixture and lyophilizing the liquid mixture to obtain a lyophilized polypeptide composition.
