Peptide Library
Based on 83 publication(s) in Google Scholar
Peptides are a group of biologically active substances that are involved in various cellular functions of organisms. Peptides are often used in functional analysis, vaccine research and especially in the field of drug research and development. At present, more than 80 peptide drugs have reached the market for a wide range of diseases, including diabetes, cancer, osteoporosis, multiple sclerosis, HIV infection and chronic pain.
MedChemExpress (MCE) offers a comprehensive collection of 2,593 peptides, including bioactive peptides, amino acid derivatives, and blocking peptides. MCE Peptide Library can be used for peptide library screening, peptide drug discovery, vaccine development, target verification, structural activity research, etc.

Product Details
A collection of 2,593 Peptide compounds supplied as pre-dissolved Solutions or Solid.
96-well storage tube or 96-well plate: 1st and 12th column are left empty.
384-well plate: the first two columns and the last two columns are left empty.
Compounds with different concentrations or dissolved in different solvents will be put on separate plates.
This way of layout may increase the number of plates because there could be three solvents and three concentrations.
If you have other requirements, please let us know.
