Proteintech is a leading provider of primary antibodies with an extensive portfolio of polyclonal, monoclonal, and recombinant antibodies.

All our primary antibodies are developed and validated in-house by Proteintech scientists to ensure high specificity and lot-to-lot consistency.

Polyclonal Antibodies

Recognize multiple epitopes on the protein of interest. Binds with very high affinity. Good for low abundant targets, rare species and mutated proteins.

Proteintech polyclonals are raised in rabbit.

Monoclonal Antibodies

Recognize a single epitope on the protein of interest. Low background, highly specific. Good for mid-high abundant targets. ​

Proteintech monoclonal antibodies are raised in mouse.

Recombinant Antibodies

Genetically defined monoclonals, recombinantly produced. Unrivalled reproducibility. Good for long-term, high-level projects.  ​

Proteintech recombinant antibodies are raised in rabbit. Learn more about our recombinant antibody production process.
