    摘要: Novel uses of biological membrane microarrays and a new product platform or assembly are described. The invention involves cell membranes from different tissues or cells or organelles to fabricate tissue-specific cell membrane microarrays. The invention provides methods for identifying the relative distribution and/or abnormal expression levels of different membrane bound proteins, including G protein coupled receptors, in specific tissues or cells. In addition, the invention provides methods for screening target proteins that interact with membrane receptors.

    摘要: Disclosed are methods to classify human ether-à-go-go related gene (hERG) ion channel modulators using label-free biosensors. Disclosed is the use of label-free resonant waveguide grating (RWG) biosensors to reveal the patterns of the DMR signals of hERG modulators across three types of cell lines (a native cell line endogenously expressing hERG, a native cell line without hERG and its engineered cell line stably expressed hERG), as well as the corresponding modulation index of the modulators molecules against a hERG activator acting on a panel of markers/cells, particularly the known hERG activator mallotoxin DMR signals in the two hERG expressing cell lines.
