Applications: Protein A Blue-Separopore® 4B-MB functions same as conventional Protein A affinity beads, but offers enhanced visibility due to blue colored Separopore® macrobeads. The blue colored beads help provide visual monitoring to avoid the accidental loss of beads during pull-down in immunoprecipitation (IP) procedures, thereby increasing efficiency and yield.

  • Affinity matrix with immobilized Protein-A by CNBr activation coupling method.
  • For immunoprecipitation and co-immunoprecipitation experiments.
  • Reliable tool to purify monoclonal and polyclonal IgG from ascites, serum and cell culture supernatants.

Note: Separopore® is a cost-effective equivalent to Sepharose® in all of its physical properties and binding characteristics.
