ChromoTek is a pioneer in the development and commercialization of innovative reagents based on camelid Nanobodies. In contrast to traditional antibodies, Nanobodies consist of only one single polypeptide chain; they are the smallest known antibodies. They are the antigen binding domains or variable heavy domain of heavy chain antibodies (VHHs) from alpacas, llamas, or camels. Due to their size and single chain characteristic, they provide a higher level of performance than conventional IgG antibodies in applications such as immunoprecipitation, immunofluorescence, live cell imaging, biosensor assays, and protein purification. The ChromoTek GFP-Trap® is a ready to use affinity resin for immunoprecipitation (IP) of GFP-fusion proteins. GFP-Trap consists of an anti-GFP Nanobody/ VHH coupled to agarose beads, magnetic agarose beads, Magnetic Beads or multiwell plates. ChromoTek’s GFP-Trap is referenced in more than 1,700 scientific articles and is the gold standard for IP of GFP fusion proteins.
