Hi, during my co-IP experiment after blocking the Pierce Protein A/G Magnetic beads in a 10% BSA solution. I add the beads to my samples (which were incubating overnight with the co-IP antibody) and place them on a rotator for an hour at room temperature. However, the beads start visibly clumping in the sample after a while. Any explanations as to why this is happening? And any suggestions to prevent it from occurring? Thank you
