Latest Market Trends

Shift from Single-Target Engineering to Modular Multi-Domain Optimization

A major trend is the transition from narrow optimization of isolated antibody regions to integrated refinement of multi-domain constructs such as trispecifics, receptor-blocking pairs, and transport-enabled scaffolds. Developers are moving toward engineering pipelines that address interactions between variable regions, Fc domain, and linker elements in a coordinated manner. This shift supports the creation of antibodies that operate across multiple biological pathways, expanding development possibilities beyond traditional single-antigen formats.

Shift from Wet-Lab Heavy Screening to Algorithm-Guided Variant Prioritization

The major trend is the movement from exhaustive bench-based screening toward computational triaging that narrows variant pools before laboratory evaluation. Companies are adopting probabilistic scoring, structural simulation, and sequence-pattern learning to pre-select variants with higher improvement potential. This transition reduces experimental workloads and supports faster refinement timelines, particularly in early discovery phases where libraries can reach millions of candidates.
