Peptide Discovery - Overview

Features
  • Innovative improvements in mRNA display enable screening from a library of >10^13 peptide.
  • Practical biosynthesis & assays enable rapid selection and activity based evaluation.

Peptides with wide varieties and high-affinities(~nM) can be obtained with high success rate.

Track Records 

Hit peptides have been obtained toward >20 targets with our platform.
High binding affinity was achieved as the Hits in initial screening.

In-House Projects
Table of track records. FUJIFILM has conducted over 20 evaluation projects to date, with dissociation constant ranges for 11 of these shown in the table. In several cases, initial screenings have yielded dissociation constant values below 1 nanomolar.

Figure describes knockdown activity of POC, peptide-oligonucleotide conjugate. In the case of integrin expresssing U87-MG cell, use of POC provides the same level of knockdown activity as use of usual transfection method with Lipofection reagent. Onthe other hand, in the case of Hela cell, not expresssing integrin, POC does not effect, indicating POC’s knockdown activity is cell-selective manner. Under another culture conditon, POC gives knockdown efficiency up to 80%.
