The invention relates to a
sorbent material. The
sorbent material comprises a plurality of cross linked monovinyl monomers defining a matrix, in a ratio of the volume of hydrophobic monovinyl monomers to hydrophilic monovinyl monomers of approximately 5:95 to approximately 40:60, the matrix being bufferable to pH ranges from approximately 5 to approximately 9, and, of particle sizes between approximately 10 micrometers to approximately 300 micrometers. The
sorbent is used in chromatographic columns to promote binding of
Immunoglobulin G (IgG) from
blood plasma, for its isolation, such that the isolated IgG is then extracted from the sorbent. The sorbent is also used in chromatographic columns to promote binding of
Immunoglobulin G (IgG)
monoclonal antibodies from transgenic milk, for their isolation, such that the isolated
IgG monoclonal antibodies are then extracted from the sorbent.
