The TurboGFP-Trap is an affinity resin for immunoprecipitation of TurboGFP-fusion proteins.
It consists of an anti-TurboGFP Nanobody/ VHH, which is conjugated to beads.

About TurboGFP

The dimeric green fluorescent protein TurboGFP is derived from the green fluorescent protein CopGFP of the copepod Pontellina plumata (Shagin et al., 2004). It possesses bright green fluorescence with excitation maximum at 482 nm and emission maximum at 502 nm. TurboGFP is a fast maturating protein: its fluorescent signal is visible earlier than other green fluorescent proteins. TurboGFP shares only about 20 % sequence identity with jellyfish GFP variants. Therefore, most anti-GFP antibodies including the GFP-Nanobody used in GFP-Trap do not bind to TurboGFP.
