Cell Surface Proteomics Service

Cell surface proteins form a unique class of proteins, playing critical roles in managing cell function and facilitating communication between the cell and its environment by transporting metabolites, ions, and other solutes.

 

Cell surface proteins vary across different cell types and can even change within a specific cell type under normal or diseased conditions. Consequently, cell surface proteins have numerous significant applications, such as distinguishing cell phenotypes and disease states and aiding research and development for prognosis and therapeutic targets. The cell surface contains key biomarkers and potential drug targets for various diseases. Approximately 70% of current biopharmaceuticals in development target cell surface proteins, underscoring the importance of studying surface proteins and their potential role in developing novel cancer therapies.
