Protein A and G Antibody Purification Kits

Immobilised Protein A and G are designed for binding the constant domains of immunoglobulin (Ig) molecules. Immobilised Protein A is coupled to 6% highly cross-linked agarose beads by a proprietary coupling method that provides high coupling efficiency for immunoglobulins and minimal protein A leaching. The binding capacity of Protein A is 18 to 43 mg Human IgG per ml resin.

Immobilised Protein G is a modified form of Streptococcal group G so that it does not bind to albumin. Protein G is coupled to 4% cross-linked agarose beads by a proprietary coupling method that provides high coupling efficiency for Ig and minimal protein G leaching. The binding capacity of Protein G is >20 mg Human IgG per ml resin.

: Immobilised Protein A and G Resin are available as resin-alone, prepacked columns or supplied in kit formats containing columns, wash and elution buffers.
