1. Peptides

Peptides are a group of biologically active substances that are involved in various cellular functions of organisms. Peptides are often used in functional analysis, antibody research, vaccine research and especially in the field of drug research and development. Peptides have a variety of biological functions, such as, anti-thrombosis, anti-hypertension, antibacteria, antivirus, anticancer and antioxidation, immunoregulation, and cholesterol-lowering effects.

MedChemExpress (MCE) offers a comprehensive collection of tag peptides, amino acid derivatives, blocking peptides, and bioactive peptides to clients in pharmaceutical and academic institutions all over the world. The bioactivity and safety of most bioactive peptides are confirmed by preclinical research and clinical trials. The peptides target on caspase, ACE, serine protease, integrins, JNK, and so on. And some peptides are the linkers for antibody-drug-conjugation. Tag peptides include common tags such as HA, FLAG, and c-Myc peptide.

Product quality is the key to our success and we take pride in offering only the highest-grade products. Product identity, quality, purity and activity are assured by our robust quality control and assurance polices, programs and procedures. We perform thorough analytical tests (HPLC and LC-MS), stability tests and activity assays on our peptides and the test results are available to clients. Comprehensive information such as purity, length, modification, sequence and recommended solvent will be provided.
