Polypeptide array is a new kind of biochip, which is the most direct research technology to reveal various diseases and biochemical phenomena in the post-gene era. In this technology, any designed amino acid sequence, polypeptides, are synthesized in situ at high density on specially treated chips, each chip can hold thousands or more of the polypeptides. The technology can be used to detect the binding sites/domains of proteins and other proteins or substances (such as polysaccharides, nucleic acids, chemical compounds, etc.). The array technology can synthesize polypeptide amino acid sequence in situ on the chip according to the amino acid sequence of known protein according to the principle of sequence drift, or can synthesize amino acid sequence arbitrarily according to the structure of the substance to be tested, and these polypeptides are arranged on the chip in a certain order with high density. Then, the test substance reacts with the chip, and the site/domain that has binding reaction with the test substance is found through the immunodetection technology. Then the data is input into the computer to process the three-dimensional structure of the protein, so as to find the binding site of the protein and the test substance.

We offer a very fast and cost effective custom peptide array service to meet your drug development pathway needs. We can also provide a full range of downstream services based on our advanced peptide array platform.

1. High density and high throughput: tens of thousands of protein-polypeptide biochemical reactions can be measured simultaneously.
2. High specificity: deeply reveal the protein binding mechanism and accurately locate the specific epitope of the antibody and the protein binding region.
3. Low cost, short cycle and simple operation: the cost of polypeptide array chip based on chemical synthesis is one hundredth of that based on biological culture.
4, accurate and reliable: stable purity, clear results, intuitive, easy to analyze.
