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.

Nano-Traps
