Nano-Boosters & Nano-Labels

2
Size comparison between Nano-Booster/ Nano-Label (fluorescently labeled Nanobody) and IgG complex consisting of primary and secondary antibody
Schematics of Nano-Booster application: The signals of GFP- and RFP-fusion protein decrease after cell fixation. The addition of GFP-/ RFP-Booster enhances the signals.

ChromoTek's Nano-Boosters & Nano-Labels are fluorescent probes. They consist of very small recombinant antibody domains, also called Nanobodies or VHHs. These single-domain alpaca antibody fragments are covalently coupled to fluorescent dyes.

  • The Nano-Boosters GFP- and RFP-Boosters enhance the signal of fluorescent proteins
  • The Nano-Labels Vimentin- and Histone-Label fluorescently label endogenous cellular proteins
  • The Spot-Label fluorescently labels the Spot-Tag, a 12-aa peptide tag

Applications
Immunofluorescence (IF): immunocytochemistry (ICC) and immunohistochemistry (IHC)
Cleared tissue, organ, and animal (DISCO) staining for light-sheet microscopy imaging
Super-resolution microscopy (SRM)

Why size matters

Nano-Boosters & Nano-Labels (also termed fluorophore-conjugated Nanobodies) are much smaller compared to conventional primary plus secondary IgG antibodies (IgG complex). Due to their small size, VHHs are probes for effective labeling with minimal fluorophore displacement for super-resolution microscopy.

Benefits

  • Higher image resolution and higher labelling density
  • 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
  • Stabilization, enhancement and reactivation of fluorescent signals
  • Monovalent VHHs do not cluster their epitopes
  • Consistent and reliable performance due to recombinant production and monoclonality
  • Validated antibodies: structure and function characterized
