Thiophilic Adsorption Chromatography (TAC) is a group-specific, salt-dependent purification technique with distinct adsorption affinity towards immunoglobulins and α2-macroglobulins. The term ``thiophilic'' refers to an affinity for sulfone groups that lie in close proximity to thioether groups. TAC has proven to be an easy and economical method for purification of many types of proteins, especially immunoglobulins. What makes TAC attractive is the ability to purify all types of immunoglobulins under universal and mild conditions (neutral pH). BioVision's Hi-Bind? T-Gel Agarose beads provide up to 30 mg protein per ml settled beads capacity and allow rapid purification of any type of immunoglobulins from serum, ascites, tissue cul
