Reviews
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
FH Keerthi (Verified Customer) (10-06-2025) | I have been using the GFP trap magnetic agarose beads for pull down experiments of GFP tagged protein of interest. I am highly satisfied with the quality of the product and also the results, considering the fact that the samples I use are known to be low yielding cells. This was one of the major experiments I did in my PhD and I am so happy with the results. Additionally, the whole Proteintech team was extremely helpful and always available for any questions I had. I have already recommended the products to some colleagues!

FH Antonio (Verified Customer) (10-03-2025) | GFP-Trap magnetic beads are fast and allow us to immunocapture and purify our protein at a glance, we can process it for further analysis. It allows to have great reproducibility between replicates.
|
FH Morgane (Verified Customer) (09-30-2025) | Works very well on a lower number of cells. Clean Elution. Quick and easy to use !
 |
FH Monifa (Verified Customer) (09-19-2025) | GFP-tagged sample bound to beads slurry according to the binding capacity advertised. I eluted in 2x SDS sample buffer and saw specific elution with GFP-tagged samples. It was great to not have to deal with heavy or light chain leakage into the elution.
|
FH Precious (Verified Customer) (08-24-2025) | The GFP-trap nanobody worked really well for our GFP pull down experiments coupled to UV-RNA-immunoprecipitation.
|
FH Maurizio (Verified Customer) (04-30-2025) | Excellent reagent. The pull-down efficiency of the GFP-Trap system is way higher than the one obtained with standard anti-GFP antibodies.
 |
FH Timo (Verified Customer) (01-30-2025) | CoIP resulted in a very clean result and the technical support was excellent. Will 100% recommend!
|
FH Karel (Verified Customer) (11-20-2024) | We achieved very nice recovery of protein of interest.
|
FH Haifei (Verified Customer) (09-13-2024) | Easily followed protocol. Clean results.
|
FH Alen (Verified Customer) (08-20-2024) | Great and convenient product
|
FH Margaux (Verified Customer) (06-11-2024) | I used GFP-TRAP to isolate GFP-tagged proteins. It was very efficient and it's a real advantage not to have to deal with heavy and light antibody chains.
|
FH Titouan (Verified Customer) (06-11-2024) | Very efficient pull-down of GFP-tagged protein from cell lysates (293T, Hela...) and very easy to use
|
FH Mona (Verified Customer) (08-03-2023) | I purified GF tagged protein and efficiency was almost 100%
|
FH Rhys (Verified Customer) (11-08-2022) | Used for IP of a eGFP tagged construct, easy to use and excellent efficiency.
|
FH Peter (Verified Customer) (10-24-2022) | Best system I have used for GFP IPs
|
FH Amy (Verified Customer) (09-02-2022) | Efficient pull down of GFP-tagged protein from HEK293T cell lysates.
|
