XenoAptamers
Xenolis provides a series of high-affinity and high-specificity XenoAptamers targeting proteins for detection, diagnostics, and therapeutics. Our target proteins are produced using the HEK293 expression system and glycosylated.
Our proprietary platform allows us to generate XenoAptamers with sub-nanomolar Kd values to unlock novel discoveries and applications.
We provide various types of XenoAptamers, including XenoAptamer bodies, mini-hairpin XenoAptamers, and modified XenoAptamers, as wll as customized ExSELEXâ„¢ selection and development services.
We utilize our many years of experience and the latest high-throughput, automated technologies to deliver XenoAptamer-based solutions to the customer base for a wide range of life science applications.

XenoAptamer Molecular Affinity Ruler
Xenolis offers a collection of XenoAptamers with diverse Kd values for the same targets. This molecular affinity ruler set is beneficial for evaluating and enhancing aptamer applicability in diagnostic device developments and drug assessments. By substituting UBs in XenoAptamers with natural bases, a set of XenoAptamers with various Kd values can be created.

DNA/RNA Engineering
by Genetic Alphabet Expansion
Xenolis is offering reagents for genetic alphabet expansion systems in replication and transcription. The Ds−Px pair system can be used for replication and PCR with Ds-containing DNA templates and Ds and Px substrates (dDsTP and dPxTP) using 3’-exonuclease-proficient DNA polymerases, such as DeepVent and AccuPrime™ Pfx. The Ds−Pa pair system can be used for the site-specific incorporation of functional Pa in RNA transcripts by T7 RNA polymerase using Ds-containing DNA templates and modified PaTP, such as NH2-, biotin-, and DFHBI-conjugated PaTPs.
We offer custom synthesis of DNA fragments containing Ds, as well as dDsTP, dPxTP, and various modified PaTPs, for the preparation of DNA templates. We are equipped to synthesize DNA oligonucleotides (up to 50-mer) at PAGE purification grade. For assistance with DNA design and non-natural transcription substrates, please contact us.
