Carrier-Free Antibodies for Conjugation and Functional Assays

 

 

Carrier-free antibodies are formulated without common carrier proteins or preservatives that may interfere with antibody labeling, multiplex detection, or functional assays. These formulations provide researchers with greater flexibility for conjugation, buffer optimization, and customized assay development.

 

Whether you are developing a multiplex imaging panel, preparing directly conjugated antibodies, or optimizing a cell-based or bead-based assay, carrier-free antibodies can help reduce formulation-related interference and support more controlled experimental design.

Why use Carrier-Free Antibodies?

  • Conjugation-ready: Suitable for labeling with fluorophores, enzymes, oligonucleotides, metals, nanoparticles, or other tags.
  • Greater assay flexibility: Allows researchers to optimize antibody concentration, buffer, and detection strategy for their workflow.
  • Reduced formulation interference: Avoids additives that may affect labeling efficiency, live-cell assays, or specialized detection platforms.
  • Useful for advanced applications: Supports multiplex ICC/IHC, flow cytometry, imaging mass cytometry, ELISA development, and functional assays.
