Proteins & Peptides

Proteins are organic molecules made from amino acids that exist in all living organisms. Proteins serve a range of vital biological functions, including: catalysing metabolic reactions, transporting and storing molecules (such as oxygen), controlling growth and differentiation, and transmitting nerve impulses. Peptides are similar to proteins but are distinguished by their smaller size; they are short chains of amino acid monomers with fewer than fifty amino acids.

We offer over 8,000 natural and recombinant proteins and peptides, including: CD antigens, chemokines, cytokines, enzymes, growth factors, hormones, immunoglobin proteins, neurotrophins, signalling proteins, and viral and bacterial antigens. Our proteins and peptides are high purity reagents extracted from the tissues and fluids of multiple species or produced in mammalian, bacterial, or insect expression systems. Every product is validated with standard QC procedures and tested for bioactivity and low endotoxicity. We also offer a unique range of transmembrane proteins including nanodiscs, virus-like particles, and membrane nanoparticles.
