Overcoming Affinity and Expression Bottlenecks in TCR Discovery

22 October 2025

3:00pm

Struggling with low-affinity TCRs or poor yields? Learn scalable workflows to boost expression, improve binding and speed TCR-TCE discovery.

T cell receptor–T cell engagers (TCR-TCEs) are gaining momentum as a targeted therapeutic strategy. Yet many discovery programs are slowed by technical roadblocks that limit candidate quality.

Common challenges in TCR discovery

Many researchers continue to face obstacles such as:

  • Low-affinity TCRs from phage libraries
  • Poor expression yields of soluble TCRs (sTCRs)
  • High endotoxin from E. coli refolding
  • Limited throughput for candidate screening
  • Gaps in internal expertise to advance next-generation TCR-TCEs

This webinar will present practical strategies and case studies to address these challenges and accelerate early-stage discovery.

What you’ll learn

Join Dr. Jiansheng Wu (SVP & Head of CRO Services, WuXi Biologics) to explore two proven strategies that can accelerate your TCR pipeline:

  • CHO-based expression of sTCRs (~100 mg/L): scalable, high-throughput and low-endotoxin production
  • Optimized phage display affinity maturation: boosting TCR binding by up to ~10,000-fold

“If you’re still refolding TCRs in E. coli, it’s time for an upgrade.” – Dr. Wu

Whether you’re starting a new TCR program or optimizing an existing platform, this session will offer actionable strategies to accelerate discovery and improve candidate quality.
