Characteristics and Advantages

Protein A Resin

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)

Uni®Mab was secessfully applied in purification of hIgG from human serum. (Experimental:Column:7 mm× 25 mm  Sample:human serum,5 mL  Equilibration Buffer:20mM PBS,pH 7.0

0.15 M NaCl   Elution:0.1 M Glycine ,pH 3.0  Residence time:4 min )
