Epidermal growth factor receptor (EGFR) is a huge transmembrane glycoprotein with a molecular weight of about 180KDa and has ligand-induced tyrosine protein kinase activity. EGFR is involved in the regulation of various physiological processes such as cell proliferation and differentiation and apoptosis, and is overexpressed or mutated in various epithelial cancers, gliomas, and glioblastomas. Therefore, imaging analysis of EGFR is very important for the treatment of these types of cancers.

Epidermal Growth Factor Receptor Imaging Analysis

Currently, there are limited methods to directly visualize proteins and complexes with high spatial resolution in the complete cell membrane, which hinders researchers from understanding the spatial structure of EGFR on the cell surface. In recent years, with the development of single molecule fluorescence and single particle tracking technology, the structure and mechanism of EGFR dimer and oligomer have been widely studied, but the entire receptor population cannot be revealed in most cases.

CD BioSciences has been committed to the development of fluorescent probe and imaging technology for many years. We can use near-field scanning optical microscope (NSOM) to image EGFR in cells at the nano level and to study the distribution of EGFR and the structure of its aggregates.
