Custom Labeling

Simply choose your molecule and conjugation, and let Cisbio label it for you.

We provide labeling on antibodies, peptides, small molecules, oligonucleotides, or just about any biomolecule of interest. Our promises:

  • Selection of the optimal fluorophore for your experiment
  • Fast turn-around time
  • Test size for assay development or proof-of-concept
  • Batch size with scaled-up implementation of large milligram quantities

Fluorophores and conjugation chemistry

Cisbio’s proprietary HTRF fluorophores include Europium and Terbium cryptates, and red-shifted acceptor donors d2 and XL665. Other fluorophores and tags are also available, including Biotin and DNP.


While HTRF is Cisbio’s flagship application, we also label molecules used in high-content screening (HCS), fluorescence-activated cell sorting (FACS), or any application requiring high quality dyes and chemistry.
