GoldenSite™
best-in-class therapies through
radically optimized protein conjugation
for next-generation treatments.
“Effective treatments that let
patients continue living their lives,
created by passionate people
through boundary-pushing science.”
HOW IT WORKS
science
Our unique differentiators:
- GoldenSite™: Every site in a protein available for site-specific conjugation. Find your GoldenSite™ for best conjugate performance.
- Perfect definition: Lighting-fast click-chemistry enables >99% conjugation at any site. Perfect homogeneity, perfect peace-of-mind.
- Smart chemistry. Simple manufacturing: No catalyst, no enzyme needed. Simply purify, conjugate and done.
What we are aiming for:
our benefit for developers
Enhance your drugs therapeutic window through
site optimization that achieves unconjugated
antibody-like biophysical profiles, enabling
higher dosing with reduced toxicity.
De-risk clinical development with
conjugates showing no increased
hydrophobicity, self-interaction, or
polyreactivity compared to naked
antibodies – predicting superior
pharmacokinetics and safety.
Leverage AI-ready datasets from systematic
site profiling to predict optimal conjugation
positions for new targets and payloads.
our benefit for patients*
Experience reduced side effects from ADCs
designed with optimized conjugation
sites that minimize off-target toxicity
and treatment-related adverse events.
Receive more potent therapies as
improved therapeutic windows allow
physicians to administer higher,
more efficacious amounts without
increased safety concerns:
Stay on treatment longer with better-
tolerated therapies reducing the substantial
discontinuation rate seen with current ADCs
due to adverse events.
*Disclaimer: While our preclinical data strongly
suggests these patient advantages, VALANX techn-
ology has not yet entered clinical trials. These
benefits represent our scientific hypothesis based
on laboratory evidence and established ADC
development principles.

Scientist Upstream Process Development (m/f/x)
This role is ideal for a dynamic, hands-on scientist eager to drive the translation of research processes starting from stable cell line generation through to technology transfer for GMP-compliant manufacturing. The successful candidate will develop, optimize, and scale upstream processes for antibody and antibody-drug conjugate (ADC) production in a fast-paced, collaborative biotechnology environment.
