Peptides and Proteins
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.
