Background

Kinases are one of the most extensively studied enzymes in biology and medical research. Kinases catalyze the transfer of phosphate from a donor ATP molecule to a wide variety of cellular substrates such as proteins, nucleic acids, lipids, and carbohydrates. Kinase activities are tightly regulated under normal physiological conditions. However, dysregulation of kinase activity under pathological conditions leads to many diseases such as cancer, cardiovascular diseases, neurological diseases, and inflammatory diseases. Consequently, kinases have become attractive therapeutic targets and technologies monitoring changes in kinase activity have emerged as important tools for drug development.

Kinase activity assays focus on directly or indirectly quantifying the production of catalytic products. Quantifying kinase activity requires detecting either the production of phosphorylated products or the amount of ATP used or ADP formed. Understanding the different types of kinase activity assays is a critical step for successful kinase research and drug discovery. Colorimetric assays have gained great interest due to their inherent advantages, including low cost, simple operation, adaptable sensitivity, quick response, wide linear range, and the possibility of qualitative or semiqualitative identification by the naked eye.

Colorimetric ELISA

Different colorimetric assay formats have been reported for measuring kinase activities and screening inhibitors. Enzyme-linked immunosorbent assay (ELISA), which has the advantages of easy quantification, high specificity, high sensitivity, and high throughput, has become a powerful method for measuring protein phosphorylation. We have developed highly sensitive colorimetric biosensors for kinase activity detection by using ELISA to help our customers achieve desired results.

Nanomaterials-Based Colorimetric Assays

With the achievements of nanotechnology and nanoscience, nanomaterials-based colorimetric assays have emerged to be promising alternatives to conventional colorimetric ELISA. We have developed a wide range of colorimetric assay based on different types of nanomaterials, including gold nanoparticles (AuNPs), silver nanoparticles (AgNPs), palladium nanoparticles (Pd-NPs), magnetic nanoparticles (MNPs), carbon dots, etc. Our simple, robust, and universal assays enable our customers to make faster progress.
