General description

Protein A-Sepharose has been used to develop strategies for investigating protein interactions, to improve the detection of celiac disease, and to study diabetes in children.[1]

Application

Protein A-Sepharose is used for affinity chromatography, antibody purification and characterization, immunoaffinity matrices, protein chromatography, protein A, G and L resins, and recombinant protein expression and analysis. Protein A-Sepharose has been used to develop strategies for investigating protein interactions, to improve the detection of celiac disease, and to study diabetes in children.
Protein A-Sepharose Fast Flow from Staphylococcus aureus has been used:
  • in co-immunoprecipitation assay[2]
  • in immunodepletion[3]
  • to purify IgG from human serum and plasma[3]

Questions

  1. For ChIP-seq experiments, what is the correct procedure to prepare a 50% Protein A–Sepharose bead slurry? Specifically, can the slurry be prepared by pelleting 20 µL of the stock beads at 1,000 g for 30 s, discarding the storage buffer, and resuspending
