We offer a wide range of peptides and recombinant proteins for use in your experiments. Our custom peptides and peptide libraries are available with flexible modification, conjugation, and isotopic labeling options.

For applications including proteomics, biomarker discovery, antibody production, and more, our peptide synthesis service can help you design and synthesize reliable and validated peptides. Our recombinant proteins can be used as standards and controls in cell assays and immunoassays. In addition, we offer function, high-quality, purified growth factors for use in cell culture.

Featured peptide & protein categories

We offer multiple grades of stable isotope-labeled peptides for each stage of your targeted proteomics workflow, from discovery to clinical.

Streamline selected reaction monitoring by combining peptide identification and target quantitation.

Accelerate your high-throughput selected reaction monitoring assays using these crude peptide libraries.

Designed specifically for the identification of immunogenic protein sites, these custom crude peptide libraries feature a low-toxicity formulation.

A broad range of proteins, including functional growth factors, recombinant and native proteins from Thermo Scientific Pierce and Sino Biological.

Explore our collection of high-quality proteins for use as growth factors and cell-signaling molecules, such as cytokines and chemokines.

Like our Custom Peptide Service, but with over 400 N-, C-terminal, and internal modification options available.
