Protein A Agarose CL-4B

Catalog # Pack Size Price(USD)
ICP1001 10 mg $150.00



Product Description

Protein A binds to the immunoglobulin G and M of many mammalian species. The product is protein A chemically linked to beaded agarose through a stable covalent linkage. The immobilized protein A on the beaded agarose could be utilized for the immunoprecipitation and purification of both polyclonal and monoclonal antibodies from mammalian species.












10 mg; 1 mL Agarose Beads suspended in 2 ml slurry in glycerol


Ligand Immobilized

10 mg protein A/mL matrix. The matrix linking chemistry is stable when eluted with weak acid (pH 2-3) and could be re-usable with no apparent loss of IgG binding capacity. 


Binding Capacity

30-40 mg rabbit IgG/mL beads as tested using rabbit serum





Scientific Description

Protein A agarose consists of the native protein A immobilized on 4% cross linked agarose beads. It is made for the binding of immunoglobulins. Protein A is very heat and acid stable.


Storage & Stability

Product is stable for 30 days at ambient temperature For extended storage store product at 4 to–20ºC.
