Antibody Purification - Protein A / G affinity Purification:
 
 
Main Process:
 
Fig1 Protein A / G affinity Purification
 
 



Protein A/G Affinity Purification Packages:
 
--Customer provides antiserum, and we will purify antibodies (IgG, IgM, IgD, IgA and IgE) according to the customers' specific requirements

--Purification scale: μg ~g

--Quality Report: antibody concentration, SDS-PAGE analysis results
 
Antibody Purification - Ligand Affinity Purification:
 
Gxene Biotech can provide a ligand chromatography column according to the antibody or antigen supplied by the customer; as shown in Figure 2, beads are agarose gel column or magnetic beads (customized or recommended by us); linker can be added to reduce the steric effect between biomacromolecules.

Applications of Affinity Chromatography:
 
--Purified biomacromolecules

--Concentration of dilute solution

--Storage of unstable proteins

--Remove residual contaminants from purified molecules

--Adsorption and purification of biomacromolecules without complementary ligands by immunosorbent

--Isolation of nucleic acids is an essential aspect of affinity chromatography applications
