——Protein A/G Agarose or Magnetic Beads
Protein A and Protein G are the most commonly used proteins for antibody affinity purification and immunoprecipitation. Protein A/G agarose or magnetic beads covalently couple Protein A and G to the medium surface, featuring stronger binding capacity, a broader binding range, and higher practicality.

Product Applications
1.Purification of Antibodies
A single step of purification can isolate high-purity antibodies from serum or ascites samples.
Enrichment of a specific protein to study its characteristics (such as post-translational modifications).
3.Co-Immunoprecipitation (Co-IP)
Enrichment of a specific protein to study other proteins that bind to it (i.e., protein-protein interactions, protein complexes, etc.).
Operation Procedure
Test Data
1.Purification of antibodies from rabbit serum using rProtein A/GAgarose Resin.
Figure 1. Electrophoresis result of antibody purification using rProtein A/G Agarose Resin
2.Use of Protein A/G Magbeads for Co-IP: Specific antibodies against p65 and cyclin-dependent kinase 9 (CDK9) are used for immunoprecipitation analysis of extracted total cellular protein.
Figure 2. Immunoprecipitants were then subjected to western blot analysis using specific antibodies against CDK9 and p65.
