GFP-Booster and RFP-Booster conjugated to Alexa Fluor® 488, 568 and 647:

• Stronger signal in confocal and standard fluorescence microscopy
• More options in super-resolution microscopy including STORM and MINFLUX
• Constant degree of labeling (DOL = 2 dyes per Booster) for higher resolution
• More than 95% labeling efficiency

Chromotek’s GFP- binding protein, an anti- GFP Nanobody, is a very small and effective tool for binding and visualizing GFP-tagged proteins. In their recent publication, Modi et al. successfully functionalized quantum dots with the GFP- Nanobody (QD GFP- Nanobody). Thus, they created a small GFP- specific label with a very strong fluorescent signal.

ChromoTek Nano-Boosters are ideal for Super-Resolution and “traditional” fluorescence microscopy because of their high affinity and extremely small size of just 2 to 3 nm. Technically speaking, the GFP-and RFP-Boosters are composed of the highly specific GFP- or RFP-binding domains of alpaca antibodies (also called “nanobodies”), covalently coupled to a selection of fluorescent dyes.
