ChromoTek Nano-Booster for super resolution microscopy is featured at Biocompare

ChromoTek’s Marketing Manager Dr. Christoph Eckert has been interviewed by Biocompare, the buyers’ guide for life scientists, on labels for super resolution microscopy.

See the interview here:

Christoph outlines the dedicated advantages of ChromoTek’s Nano-Boosters, which base on small size and superior binding:

Small size:

  • Less than 2nm epitope-label displacement minimizes linkage error
  • Better tissue penetration
  • Higher image resolution

Superior binding:

  • Stabilization, enhancement and reactivation of GFP and RFP signals after cell fixation, chemical, and thermal treatments
  • No clustering because nanobodies are monovalent

Relative size comparison of Nano-Boosters and complex of conventional primary and secondary antibody complex (IgG complex). Due to their small size, Nano-Boosters penetrate tissue better. In addition, they bind closer to their targets than conventional antibodies. This results in better staining and higher resolution.


ChromoTek Nano-Boosters bind to the following targets:

  • RFP-Booster:
    mRFP, mCherry, mRFPruby, mPlum
  • GFP-Booster:
    eGFP, wtGFP, GFP S65T, AcGFP, TagGFP, tagGFP2, sfGFP, pHluorin, eYFP, YFP, Venus, Citrine, eCFP, CFP, mCerulean

ChromoTek Nano-Boosters are derived from single-domain alpaca antibody fragments, termed VHHs or “nanobodies”. Nanobodies conjugated to fluorescent dyes are known as Nano-Boosters.


ChromoTek is the pioneer of protein-protein interactions, who has brought fluorescent proteins from cell biology as protein tags into biochemistry laboratories. Today, particularly the ChromoTek GFP-Trap is frequently used for additional applications beyond pulldowns, because of its outstanding binding of GFP-fusions.
