Reviews
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
FH Olga (Verified Customer) (04-09-2025) | Just impressed with the beads capacity and precipitation efficiency! 25 ul of beads pulled down all the mCherry from the cell lysate - and most of the mCherry fused target protein. They have much facilitated my IPs.
 |
FH Solene (Verified Customer) (11-20-2024) | mCherry and a mCherry-tagged protein (~50 kDa) extopically expressed in HEK293T were efficiently pulled down from cell lysates using RFP-trap agarose beads.
|
FH Andrea (Verified Customer) (10-05-2023) | Works well for Co-IP with RFP tag.
|
FH Julie (Verified Customer) (07-07-2021) | 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.
