Popular Design for for Purification Of Antibody Protein A Affinity Chromatography Medium UniMab 50L Recombinant supply to Ghana Manufacturer

Protein A Affinity Chromatography Medium

     Uni®Mab is a high performance Protein A affinity chromatography medium, introduced by Nanomicrotechwithits patented technology developed in-house. This medium is based on the monodisperse porous poly (methyl methacrylate) (PMMA) microspheres as the matrix, and a genetically modified protein A as the ligand, which ensures its high affinity binding of monoclonal antibodies and Fc fragment containing recombinant proteins (macromolecules). Uni®Mab has come with high mechanical strength and good pH stability. Even at a high flow rate, it still maintained a high dynamic binding capacity, meeting the demands from laboratory preparationto industrial production.

 Affinity Chromatography Procedure

Characteristics and Advantages

Chromatography Separation and Purification

Highly uniform particles
    Uni®Mab affinity chromatography medium has highly uniform particle size distribution and precisely controlled porestructure, as shown in Fig. 1.

High flow rate
    Uni®Mab affinity chromatography medium was made from polymethyl methacrylate (PMMA) microspheres (as matrix); and it would withstand the pressure of 0.5 MPa. When compared to an affinity medium with convention alagarose matrix of the chromatography media, it would make the separation process much faster, thus reducing the time purification, for hundreds of liters of large scale chromatography preparative column.(Experimental:Column:4.6 mm × 50 mm   Mobile phase:50 mM PBS,0.5 M NaCl)

Excellent loading capacity
At a high flow rate, Uni®Mab showed a significantly better dynamic binding capacity (DBC) than that of the conventional agarose type protein A medium.  The same observation was also valid, even when the residence time was increase to 4 - 6 minute.(Experimental:Column:7 mm × 25 mm   Sample:Human IgG,2 mg/mL    Equilibration buffer:20 mM PBS,pH 7.0 ,0.15 M NaCl    Elution:0.1 M Glycine ,pH 3.0)

Outstanding pH stability
Uni®Mab affinity chromatography medium could be applied in a pH range from 3 - 12, and it could be cleaned with 0.1 - 0.5 M NaOH. In a life-cycle test, Uni®Mab medium remained greater than 90% of the original dynamic binding capacity (DBC), after 100 CIP cycles with 0.5 M NaOH as CIP reagent.  (CIP procedure:Medium:Uni®Mab Column:7 mm × 25 mm   Sample:recombinant antibody(chimera)    DBC calculation:10% breakthrough   Equilibration buffer:20 mM PBS,150 mM NaCl, pH 7.2,3 CV(column volume)   Elution:20 mM Citrate,pH 3.0  CIP:0.5 M NaOH,15 CV  Re-equilibration:10 CV)
