Lee, Heajin; Liu, Wenjun; Brown, Adrienne S.; Landgraf, Ralf; Wilson, James N. published the artcile< Fluorescent Kinase Probes Enabling Identification and Dynamic Imaging of HER2(+) Cells>, Recommanded Product: 4-(4-Methyl-1-piperazinyl)phenylboronic Acid, the main research area is fluorescent kinase probe imaging HER2 cancer.
The human epidermal growth factor receptor, EGFR/ERBB/HER, family of receptor tyrosine kinases is central to many signaling pathways and a validated chemotherapy target in multiple cancers. While EGFR/ERBB-targeted therapies, including monoclonal antibodies, e.g., trastuzumab, and small mol. kinase inhibitors, such as lapatinib, have been developed, rapid identification and classification of cancer cells is key to identifying the best treatment regime. The authors report ERBB2 (also HER2) targeting kinase probes that exhibit a “”turn-on”” emission response upon binding. These live cell compatible probes differentiate ERBB2(+) cells from low-level, ERBB2(-) cells by targeting the intracellular ATP-binding pocket of ERBB2 with therapeutic inhibitor-like specificity. Beyond kinase expression levels, probe signal is linked to the phosphotyrosine-correlated activation state of the ERBB2 population. Addnl., the rapid signaling capability of the probes can report changes in activation state in live cells providing a unique type of complementary information to immunohistochem. assays of receptor kinase populations.
