Bead Conjugation

Immunoaffinity purification utilizes the highly specific binding properties of antibodies (or Fc-fusion proteins) to easily isolate ligands (or receptors) from crude mixtures with very high purities. CD BioSciences offers the ability to attach antibodies or Fc-fusion proteins to Protein A/G resins and immobilize them using chemical crosslinkers to generate custom and stable immunoaffinity resins. Affinity resins are utilized in pulldown assays, co-purifications, immunopurifications, and custom diagnostic platforms. CD BioSciences offers on-bead conjugation services that will generate custom affinity resin at a variety of scales using a variety of chemistries that will expand your capabilities for highly custom affinity purification. As a life science service expert around you, we can provide one-stop or highly customized services according to the specific requirements of customers. Please contact us directly and we will get back to you as soon as possible.
