The scientists at 21st Century Biochemicals have over 25 years of combined peptide synthesis and purification experience. Whether you require a few mg of highly purified peptide or 10 grams of a 35 amino acid peptide, the scientists at 21st Century will deliver the highest quality product at reasonable prices. In addition, Ph.D.-level scientists can assist you in choosing peptide sequences and purities to suit your specific research needs.
Quality control is a serious issue at 21st Century Biochemicals. Exclusive to 21st Century Biochemicals, we offer MS Check™ peptidesequence confirmation at no extra charge with every peptide ordered at 10mg or higher scale, 90+% purity. With MS Check™ we confirm that the peptide sequence is what you ordered. Although a vast majority of peptides are made properly by most reputable peptide companies, both human and machine errors can result in the occasional manufacture of peptides with transposed or incorrect amino acids. MS Check™ insures that our customers receive the highest quality peptides. MS Check™ is also included at no extra charge with all custom affinity antibody protocols!
