Peptide chip screening platform technical basis

Peptide chip technology

The core is the construction of a microscopic matrix containing thousands of uniquely sequenced peptides, which are sequentially anchored to a solid substrate (such as glass, microbeads, or microfluidic chips) to form a dense and ordered peptide lattice. Each point acts as a highly specific detection element capable of capturing and identifying the target molecule it matches, revealing a complex network of molecular interactions.

High throughput screening technology

Relying on the rapid development of automation and miniaturization technology, the platform can complete the interaction test of tens of thousands of peptides and a variety of target molecules (including proteins, antibodies, small molecules, etc.) at one time, greatly improving the screening efficiency and scope, and opening up new dimensions of speed and scale for scientific research.

Application of peptide chip screening platform

Antigen epitope screening

In this field, peptide chips play a key role by building a peptide library rich in potential epitopes, which can quickly lock the sequence matching a specific antibody, greatly shorten the antibody development cycle, and provide strong support for vaccine research and development, diagnostic kit innovation and basic immunology research.

Drug development and candidate molecular screening

Peptide chip technology shines in the field of drug discovery. It can efficiently screen high-affinity peptide candidates for specific protein targets. The combination of SPR and other biophysical technologies greatly improves the accuracy and efficiency of screening, and accelerates the incubation process of new therapeutic drugs.

Innovation in clinical testing and disease diagnosis

The platform provides rapid and precise analytical tools for clinical use to effectively diagnose diseases, monitor disease progression, and evaluate treatment effects by detecting changes in the activity of specific proteins, especially in the development of diagnostic reagents for cancer, autoimmune diseases and other fields.

An in-depth exploration of protein interactions

Peptide chips have demonstrated an extraordinary ability to systematically reveal protein-protein interaction networks, providing a detailed molecular map for understanding cell signaling, metabolic regulatory mechanisms, and disease pathology, and promoting a deeper understanding of complex phenomena in the life sciences.

Refinement of antibody discovery and optimization

In addition to its application in the study of antigen epitopes, peptide chips also promote the precise discovery and performance optimization of antibodies, and open up new ways to optimize the specificity and affinity of therapeutic antibodies by identifying the specific binding domain of antibodies.

A booster for basic scientific research

In the vast field of basic science research, peptide chip technology provides an efficient tool for exploring protein structure and function, post-translational modification and dynamic changes in physiological and pathological states, helping scientists to make breakthroughs in deep-seated problems in life science.

Our peptide chip screening services

Customized peptide chip services

Design and synthesize sequence-specific peptides according to customer requirements, covering a wide sequence space for screening specific protein targets.

Peptide sequences are synthesized using solid phase synthesis techniques such as Fmoc or t-Boc strategies. Support different length, different types of peptide sequences, including linear peptides, cyclic peptides, modified peptides, etc., to meet different research needs.

To ensure the purity of peptides, for advanced applications such as drug screening, purity requirements of 95% or more.

The synthesized peptide was fixed to the surface of the chip to form a peptide array. For example, using technologies such as lithography, inkjet printing, or point-of-sample robots.

Target interaction screening

incubation of drug targets of interest (such as receptors, enzymes, and transporters.) or parts of their structures (such as antibodies, ligand-binding domains) with peptide chips. The binding event of the peptide to the target is monitored and quantified by labeling the target (e.g., fluorescent labeling, radio labelling) or by utilizing label-free detection techniques (e.g., surface plasmon resonance, mass spectrometry).

Data analysis

After screening, data were collected to analyze which peptides showed the strongest binding affinity and specificity. Bioinformatics tools were used to further analyze the sequence characteristics of these peptides, including conserved sequences, structural features, and possible functional domains, to infer their drug potential.

Chemogenic evaluation

Further chemogenic evaluation of the selected peptides, including evaluation of stability and metabolic stability, cell penetration, toxicological properties, and production costs. These assessments help determine which candidate molecules are best suited as candidates for drug development.

Optimization and validation

Based on the results of preliminary screening and drug evaluation, the structure of potential peptides is optimized, such as by mutation, chemical modification and other methods to improve their activity, selectivity or pharmacokinetic properties. The optimized peptides need to be further validated for their bioactivity and safety through in vitro and in vivo experiments.
