custom reagents service

Our total synthesis based technology platform allows us to prepare ubiquitin and ubiquitin like protein reagents with various modifications:


  • assay reagents, probes, chains and ubiquitinated peptides

  • ubiquitin and ubiquitin-like proteins e.g. Nedd8, SUMO, ISG15 etc

  • electrophiles (warheads), peptides (substrate context), tags, unnatural amino acids


price & timelines

  • prices are on a project basis and bulk preparation (starting at 2 mg)

  • 6 – 8 weeks lead time for most projects



  • over the years, we have developed a large number of custom probes, assay reagents and ubiquitinated peptides for the top 10 Pharma, biotechs and academic institutions: DUB specific assay reagents probes, HTRF assays, custom electrophiles, assays reagents and probes with substrate context.

  • we also co-developed an antibody for yeast K123 Ub-H2B.
