Lyotex is pleased to offer one of the world’s largest and fastest growing peptide catalogs, containing 1,000’s of high-quality catalog peptides. With the team that has more than 10 years of experience in synthesizing peptides, Lyotex is a premier supplier of high-quality peptides to leading pharmaceutical and biotechnology companies and academic institutions. Unless otherwise specified, all peptides have >95% purity and contain TFA (trifluoroacetic acid) as counter-ions. Lyotex is proud to provide a comprehensive collection of amino acid derivatives, beta-amyloid peptides, blocking peptides, cosmetic peptides, biochemical reagents and pharmaceuticals to clients in cosmetic, pharmaceutical, academic and industry institutions all over the world.

Lyotex provides high-quality, ready-to-use peptides to make your life easier by increasing your efficiency and reducing your costs. Each month, we unveil our latest peptides designed for your most urgent research needs. Many of these peptides have been frequently cited in the literature and are now available as catalog peptides to save valuable time that you can devote to advancing your research. The biologically active peptides and their analogs are produced synthetically. Most of our peptides are available from stock with a 95% minimum purity and are delivered with HPLC, MS, AAA, and peptide solubility data to ensure the quality required for robust research data. Don’t see the sequence you need? Contact us for a custom quotation! We offer reasonable pricing and fast delivery. Free yourself from the time-consuming activity of peptide synthesis. Place your order today! We are your peptide partners from concept to commercial, custom to contract.

Lyotex stocks high-quality catalog peptides, peptide synthesis reagents, and combinatorial chemistry products. Search by product name or peptide sequence below. Our database of catalog peptides is searchable by product name or (part of the) peptide sequence.
