Drug Target Identification Solutions

The field of drug target discovery is becoming popular with great potential to advance biomedical research and chemical genomics. Since many small molecule bioactive molecules exert their functions by interacting with protein targets and an increasing number of drugs exhibit targeting of multiple proteins. Therefore, the identification of target recognition is of great importance for drug development. Drug target identification not only deepens the understanding of drug mechanism of action, but also reveals its potential therapeutic applications and adverse effects.

Revealing the target of a small molecule compound is key to gaining insight into its mechanism of action and potential toxicity. However, considering that the non-specific binding of many small molecules remains a major problem, which may reduce the accuracy of target identification and hinder the drug development process, a high-throughput, high-precision approach is necessary. To overcome these limitations, quantitative proteomics approaches have been developed in recent years, including metabolic labeling, chemical labeling, and label-free methods. These new methods are combined with activity-based protein profiling (ABPP), allowing a rapid process and accurate results.

Drug Target Identification Services

We offer drug target analysis services that combine ABPP with quantitative proteomics to identify natural and traditional drug targets.

Our discovery proteomics platform can quantify thousands of proteins per sample of almost any biological sample, such as cell culture, tissue, or body fluids. This enables the identification of significantly regulated proteins in disease models for therapeutic exploration.

Our DIA MS and 4D DIA technologies are novel, label-free methods that can target and non-target the entire proteome to detect protein changes with peptide-level resolution.
