I was using this kit to try a co-IP. My IP protein is tagged to cherry, but the very first step of IP did not work so I could not test for an interaction with other protein candidates. The antibody I used works very well. As you can see, the protein of interest is in the input and unbound fractions - meaning the RFP-protein did not bind to the RFP-trap agarose beads. Disappointed. I used buffers that were in the range that was recommended. It would be helpful if exact starting amounts of ingredients for buffers were provided since I can't test multiple conditions with a sample that only 2 reactions. I'm sure there is a way to troubleshoot, but again, I can't test multiple conditions with just 2 reactions and brain tissue is precious.
