The ChromoTek GFP-Trap^® system provides fast, reliable, and effective immunoprecipitation of GFP-fusion proteins. More than 3,000 peer-reviewed articles have already been published using ChromoTek's GFP-Trap. The GFP-Trap consists of a recombinant anti-GFP VHH (Nanobody) coupled to beads.

The GFP-Trap provides the following advantages:

• No heavy and light antibody chains 

• Very high affinity (K_D=1 pM) 

• Effective, complete pulldown of fusion proteins.

• Allows for stringent washing

• Low background 

The GFP-Trap is available with up to three different beads:

• Agarose (for very low background and high binding capacity IP)

• Magnetic Agarose (for magnetic separation and high binding capacity IP) 

• Magnetic Particles M-270  (for IP of very large proteins/complexes) 

* Limit of 1 sample per customer
