Antibody Purification

CD BioSciences provides guaranteed label-free protein purification services (an important component of prokaryotic protein expression services). Antibody purification has the same sequence information as the natural protein, which is more conducive to protein crystallization experiments and protein function research.

Antibody purification method

• Protein A/G purification:

Protein A and Protein G are bacteria-derived proteins, which have different binding properties. Protein A/G purification is a relatively simple method for antibody purification. It has a wider binding range than Protein A or Protein G alone, which can bind to all human IgG subunits. However, because Protein A/G can only bind to Fc fragments and cannot specifically screen out a specific antibody, it is generally suitable for the purification of monoclonal antibodies.

• Antigen affinity purification:

Antigen affinity purification is a better method to separate specific polyclonal antibodies, which utilizes the specific interaction between antibody and antigen. The antigen protein will bind to the Fv fragment of IgG, so specific antibodies with high affinity antigen specificity can be accurately separated from the antibody impurities, so it is generally used for the purification of polyclonal antibodies and recombinant antibodies.

Overall Solutions

CD BioSciences provides antibody preparation, antibody purification and other-stop services, including gene sequencing, recombinant antibody expression, antibody purification to affinity determination.
