Carrier-Free Formulation Customization Service

Conventional monoclonal antibodies are typically stored in PBS containing BSA, glycerol, and sodium azide. These additives can hinder effective conjugation with fluorescent dyes, metal isotopes, oligonucleotides, or enzymes: BSA competes with antibodies for binding sites and drastically reduces coupling efficiency; glycerol alters solution viscosity and slows reaction kinetics; sodium azide is cytotoxic—limiting use in cell culture—and can interfere with antibody binding and inhibit HRP activity. Our carrier-free formulations remove these interfering proteins and chemicals while preserving antibody activity, allowing direct conjugation and streamlining workflows for significantly improved labeling performance.

Service Benefits

  • High Purity and Consistency
    Eliminates background signals and byproducts by removing interfering additives.
  • Operational Simplicity
    No buffer exchanges or concentration steps are required—just add directly to your conjugation reaction to save time and reduce antibody loss.
  • Broad Compatibility
    Supports conjugation with a wide range of labels, including fluorescent dyes, metal ions, oligonucleotides, and enzymes, for applications such as flow cytometry, immunohistochemistry, and immuno-electron microscopy.
