GFP-Booster

ChromoTek offers the GFP-Booster which are GFP-binding proteins coupled to a fluorescent dye (from ATTO-TEC). The GFP-Booster can be used to increase, stabilize and reactivate fluorescent protein signals for immunofluorescence (IF) staining.

GFP-Booster

GFP-Booster for enhancing GFP

Fluorescent proteins (FP) are used as a fluorescent label to track gene expression, nuclear localization and cell dynamics. There are, however, some shortcomings to genetically encoded fluorescent proteins (FPs). For example, the photo stability and the quantum efficiency of GFP are not sufficient for super-resolution microscopy (3D-SIM or STED). Additionally, many cell biological procedures for FISH or BrdU detection disrupt the GFP signal.

The GFP-Booster consists of a fluorescent dye covalently bound to GFP-binding proteins providing high fluorescence intensities and signal-to-noise ratios.


GFP-Booster Applications

  • Immunofluorescence stainings (IF)
  • Histological stainings (IHC)
