Move quickly from idea to experiment with antibody conjugation services that are typically complete within 5 - 10 days. Whether you need an alternative conjugate of a manufactured antibody or a custom conjugation of your own antibody, the team of protein chemists will use the proprietary processes to deliver reagents that drive your success. Sanbio can help you in defining the right project requirements.

Service overview

We can provide antibody conjugation services with over 20 fluorochrome and enzyme labeling options, affordable pricing, fast turnaround times, and scalable processes from milligrams to grams.

The supplier has spent over three decades providing antibody conjugation services to the academic, biopharma, and diagnostic communities, and in that time they have developed proprietary labeling and post-conjugation purification processes that maximize signal to noise ratios. The result is a highly efficient workflow that delivers outstanding performance for ELISA, immunohistochemistry (IHC) assays, flow cytometry, western blot, and more.

Frequently Asked Questions

  • What is the minimum amount of antibody that I can send to have conjugated?

We typically recommend starting with ≥ 2 mg; however, depending on the conjugate, we may be able to accommodate smaller quantities.

  • At what concentration should I send my antibody?

The minimum concentration required will be dependent on the conjugate; however, we do offer custom concentration services, if required.

  • In what buffer should I send my antibody?

Antibodies should be supplied in a neutral buffer (e.g., PBS) with no stabilizers, preservatives, amine containing buffer salts, etc. If needed, we offer custom buffer exchange services.

  • What is the typical lead time? 

Most custom conjugated antibodies are available for shipment within 5 - 10 business days following our receipt of your antibody and purchase order.
