The invention provides a process for the separation of pea protein. The process begins with an aqueous extract or solution of pea protein, which is passed through at least one expanded bed absorption (EBA) process. The EBA process comprises contacting the aqueous extract or solution of pea protein with at least one adsorbent resin, said adsorbent resin comprising at least one ligand (L1 or L2), having particular chemical structures. Proteins of interest are isolated by eluting them from said adsorbent resin. The invention also provides various protein compositions obtainable via the method of the invention.

The present invention relates to isolation of whey proteins and the preparation of a whey product and a whey isolate. In particular the present invention relates to the isolation of a &#x3b2;-lactoglobulin product and the isolation of an &#x3b1;-enriched whey protein isolate from whey obtained from an animal. The &#x3b1;-enriched whey protein isolate provided by the present invention is besides from being low in &#x3b2;-lactoglobulin also high in &#x3b1;-lactalbumin and immunoglobulin G.

The present invention relates to a novel method for the isolation or purification of immunoglobulins (a special class of proteins) from a solution containing immunoglobulins, e.g. hybridoma cell culture supernatants, animal plasma or sera, or colostrum. The method includes the use of a minimum of salts, such as lyotropic salts, in the binding process and preferably also the use of small amounts of organic solvents in the elution process. The solid phase matrices, preferably epichlorohydrin activated agarose matrices, are functionalised with mono- or bicyclic aromatic or heteroaromatic ligands (molecular weight: at the most 500 Dalton) which, preferably, comprises an acidic substituent, e.g. a carboxylic acid. The matrices utilised show excellent properties in a 'Standard Immunoglobulin Binding Test' and in a 'Monoclonal Antibody Array Binding Test' with respect to binding efficiency and purity, and are stable in 1M NaOH.
