Reviews
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
FH Haifei (Verified Customer) (06-02-2025) | The GFP-trap beads worked well to pull down GFP tagged protein.
|
FH María-José (Verified Customer) (04-14-2025) | The GFP-Trap agarose worked extremely well for immunoprecipitation. I followed the provided instructions, and the majority of my GFP-tagged proteins were efficiently immunoprecipitated, with almost no detectable signal in the flow-through. Additionally, the western blot using a polyclonal anti-GFP antibody was very clean, with no additional bands detected.
|
FH Nadia (Verified Customer) (04-14-2025) | Easy manipulation, great yields, overall good product that I would clearly recommend.
|
FH Sneha (Verified Customer) (07-18-2024) | GFPTrap Agarose beads work very quickly and efficiently in pulling down GFP fusion protein.
|
FH Katie (Verified Customer) (01-12-2024) | These beads are wonderful! They gave us the cleanest IP I have ever seen. We are switching over to this product for all immunoprecipitations going forward.
|
FH Despoina (Verified Customer) (10-31-2023) | Our lab has been using the ChromoTek GFP-Trap® Agarose beads for a couple of years now in co-immunoprecipitation experiments, followed by western blotting. The product works well and produces clear blots.
|
FH Andrea (Verified Customer) (09-19-2023) | Works well well for co-immunoprecipitation.
|
FH Alessandro (Verified Customer) (01-19-2023) | great binding
|
FH Liam (Verified Customer) (01-11-2023) | Easy to use and produces clean/reliable results. Over the past three years, the ChromoTek GFP-Trap® Agarose have become a core experimental resource for our lab.
 |
FH Rich (Verified Customer) (09-12-2022) | works well. A little on the pricey side but worth it.
|
FH Aditi (Verified Customer) (08-17-2022) | The product works very well even with non-conventional model systems. We used it for co-immunoprecipitation and mass spectrometry analysis. We used custom buffers and the product worked efficiently. The whole protocol is also quicker than regular IP protocols. Highly recommend!
 |
FH Benedikt (Verified Customer) (08-17-2022) | We did a pull-down of a ~131 GFP-fusionprotein using the recommended buffers and incubation times (1h) and immediately pulled our protein-of-interest. Some non-bound protein was still visible, although this might be due to high amount of input lysate (500 µg).
|
FH Peter (Verified Customer) (07-04-2022) | Our lab has used the GFP-Trap Agarose beads on many occasions to successfully co-immunoprecipitate GFP fusion proteins for Mass Spectrometry and for RNA sequencing (RIP-Seq). We even managed to pulldown enough of one protein to detect it after the western blot on the PVDF membrane with amidoblack staining.
|
FH Cristina (Verified Customer) (06-10-2022) | we have been using this product for years and it's one of the fav in the lab
|
FH George (Verified Customer) (06-10-2022) | Used this for GFP immunoprecipitations from HeLa cells. Product worked as described and is much quicker and more effective than conventional immunoprecipitations. Would highly recommend.
|
FH Cristina (Verified Customer) (03-11-2022) | Great product. It is a daily must have in our lab.
