Product Information

anti-GFP VHH/ Nanobody conjugated to a fluorescent dye for IF/ microscopy.

• Description: The GFP-Booster stabilizes, enhances, and reactivates the signal of GFP-fusion proteins. Due to its small size, the GFP-Booster enables higher image quality in epifluorescence, confocal, and super-resolution microscopy:

  • Considerably higher tissue penetration rates

  • Superior accessibility and labelling of epitopes in crowded cellular/organelle environments

  • Less than 2 nm epitope-label displacement minimizes linkage error

  • Monovalent VHHs do not cluster their epitopes

  • Validation: structure and function characterized

  • Consistent and reliable performance due to recombinant production

• Applications: IF, IHC, ICC
• Host: Alpaca
• Specificity/Target: CFP, AcGFP, EGFP, GFP, GFP S65T, mClover, EGFP A206K, pHluorin, PA-GFP, sfGFP, TagGFP, TagGFP2, Citrine, Ecitrine, EYFP, Venus, YFP, Ypet; For the complete list, please click here: Fluorescent protein specificity table Nano-Booster

The alpaca GFP booster was very useful to show cellular location of PAR2-mugfp in the mouse colon. It works well at the concentration of 1:400 in a PFA fixed and Sucrose cryoprotected 10um colonic section. A must buy!

• Applications: Immunofluorescence
• Primary Antibody Dilution: 1:400
• Cell Tissue Type: Mouse colonic tissue
