Biotin • Digoxigenin • Near-Infrared Fluorophores

High-performance, reproducible conjugation with minimal antibody and protein aggregation. No outsourcing required—maintain full control by performing conjugation in your own lab.

CellMosaic® expands its proven bioconjugation toolkit with a new line of antibody and protein labeling kits powered by AqT® linker technology and PerKit® systems—designed to simplify conjugation of challenging hydrophobic detection or tagging reagents while preserving protein and Ab functionality.


Why Choose AqueaTether® (AqT®) Enabled Labeling Kits?

  • Improves the solubility of hydrophobic labels in aqueous buffers, eliminating the need for organic solvents in your system.
  • Reduces protein and Ab aggregation for stable conjugates and reproducible assay performance.
  • Preserves protein and Ab activity and binding performance.
  • Delivers high labeling efficiency with consistent results.
  • Enables simple, in-house workflows—no CRO required.
