Nano-Boosters & Nano-Labels

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.

Immunostaining with GFP-Booster Alexa Fluor 488 (green) and RFP-Booster Alexa Fluor 568 (red). HeLa cells were transiently transfected with Tom70-eGFP and PCNA-mRFP. Scale bar, 10 µm. Images were recorded at the Core Facility Bioimaging at the Biomedical Center, LMU Munich.

ChromoTek's Nano-Boosters & Nano-Labels are fluorescent probes. They consist of very small recombinant antibody domains, also called Nanobodies or V_HHs. 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, V_HHs 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 V_HHs do not cluster their epitopes
Consistent and reliable performance due to recombinant production and monoclonality
Validated antibodies: structure and function characterized
