Coming Soon: GMP-Grade Recombinant Monoclonal Antibody Conjugates for Cell Therapy Manufacturing & QC

Incorporate robust, flexible CAR-T Cell Enrichment and Detection into Your Manufacturing and QC Workflows

CST revolutionized pre-clinical CAR cell characterization with universal recombinant monoclonal antibodies specific to the ubiquitous Whitlow/218 and G4S linker sequences of scFv-based CARs. This innovation enabled scientists to use a single reagent for a variety of assays without the time or cost of developing anti-idiotype antibodies for every CAR construct.

These trusted antibody conjugates, manufactured to be GMP-grade, are intended to simplify enrichment of G4S linker CAR+ cells and increase productivity for in-process QC and lot release assays. When pre-clinical development teams use the same reagents, handoffs to clinical production can be that much easier.

G4S Linker (E7O2V) Rabbit Monoclonal Antibody (Biotin Conjugate) (GMP-Grade)

  • Enrich any G4S linker-containing CAR-T cell with one reagent
  • Biotin-conjugated antibodies are amenable to magnetic bead-based CAR-T cell enrichment on cell therapy manufacturing instrumentation
  • Standardize percent CAR-positive cells and mitigate issues associated with low transduction efficiencies
  • Designed and manufactured to GMP-grade reagent standards (Full GMP certification and commercial quantities available mid-2026)
