Posted by Christoph Eckert on Jan 29, 2020 5:37:07 PM

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

GFP- Nanobodies and RFP- Nanobodies conjugated to quantum dots

Posted by Christoph Eckert on Jul 12, 2018 8:39:33 AM

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.

Nano-Booster FAQs

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.
