Natriuretic-Peptide-Receptor-C_Antibody-470x200

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

Our Standard Peptide Synthesis Service offers custom peptides with over 400 modifications options available to help meet a variety of research needs. Peptides between 2 and 110 amino acids in length, a range of scales (1 mg–1 kg+) and purity (crude to >98%) are available.

The HeavyPeptide AQUA Custom Synthesis Service provides isotopically labeled, AQUA (Absolute QUAntitation)-grade peptides for the relative and absolute quantitation of proteins.

PEPotec SRM Custom Peptide Libraries are optimized for selected or multiple reaction monitoring (SRM/MRM) methods of absolute quantitation by mass spectrometry.

Purified, tested recombinant proteins including Gibco PeproTech bioactive proteins and Invitrogen proteins for use as biochemical standards and controls.

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

High-quality Gibco Peprotech growth factors and cytokines for cell culture and cell modulation.
