Customized and Carrier-Free Formulations

CST scientist working in the lab.

When you need a specific antibody formulation, CST can build carrier-free and other customized formulations for you. Over 99.5% of our recombinant monoclonal antibodies are developed in-house, giving us greater flexibility to quickly tailor formulations to meet your specifications.

  • We work with you to first understand your research needs, then customize the formulation for your assay and platform requirements.
  • Antibodies can be formulated at higher concentrations, and modified into other buffers.*
  • Custom formulations are ready to ship in 2-3 business days.

Carrier-Free Custom Formulations

Don't see the carrier-free antibody you need in our expanding, ready-to-ship portfolio? More than 90% of our antibodies can be custom-formulated into BSA-, glycerol-, and azide-free formulations—so they're conjugation-ready. CST® carrier-free antibodies are validated in relevant applications for specificity and reproducibility, formulated at >1 mg/ml, and are typically ready to ship in 1-2 business days.
