Immunoprecipitation assays are fundamental for studying complex protein interactions that regulate cell physiology, gene expression and drive various types of disease. While agarose A/G beads have been the prevailing choice for quite some time, many labs have recently made the switch to Magnetic Beads after seeing results that are cleaner, more consistent and require less time. Just like agarose beads, magnetic beads bind to the Fc region of IgG as a means to isolate specific proteins and protein complexes from cell lysate. The advantage of magnetic beads is that they aggregate without the stress of centrifugation, which can significantly increase the yield of delicately attached protein complexes. Additionally, magnetic beads are easy to separate from supernatant by simply using a magnetic source close to your tube. This will allow the removal of unwanted supernatant without disturbing your protein pellet. Magnetic beads are also smaller and nonporous compared to agarose beads, so nonspecific binding and background signal is minimized.
Magnetic beads provide the same ability to isolate protein complexes as agarose beads with fewer steps and easier separation of pellet from the supernatant. Together, this translates to less experimental variability, reproducible data and confidence in your results. GenScript MagBeads are optimally designed for high capacity/Fc-specific IgG binding for immunoprecipiatation assays and small scale protein purification. Choose from our Protein A, Protein G, Protein A/G, or specially tagged magnetic beads and experience cleaner results in a shorter amount of time.
