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:
A method for hit compound identification in a high throughput, label-free biosensor cellular assay, one method including, for example: generating at least one pathway-specific kinetic profile for a target receptor; generating a relational table that integrates each kinetic profile; determining a delta response with the relational table for candidate compounds screened against the target receptor; and identifying one or more hit compounds based upon the separation of the delta response from a threshold.
摘要:
The disclosure provides a system and method for characterizing a single live-cell response to a stimulus with a biosensor imaging system having cells immobilized on the biosensor at a resolution level of a single cell, as defined herein.
摘要:
Disclosed are compositions and methods for using label free optical biosensors for performing cell assays. In certain embodiments the assays can be performed in high throughput methods and can be multiplexed.
摘要:
The present application relates to compositions and methods for inhibiting the differentiation of isolated embryonic stem cells, induced pluripotent stem cells, parthenogentic stem cells, or isolated embryoid bodies into neuronal progenitor cells or neuron cells comprising a mTOR inhibitor and an effective amount of cell culture growth media. The mTOR inhibitor can be Rapamycin.
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.

摘要:
The present invention overcomes the problems and disadvantages associated with prior art arrays by providing an array comprising a plurality of biological membrane microspots associated with a surface of a substrate that can be produced, used and stored, not in an aqueous environment, but in an environment exposed to air under ambient or controlled humidities. Preferably, the biological membrane microspots comprise a membrane bound protein. Most preferably, the membrane bound protein is a G-protein coupled receptor, an ion channel, a receptor serine/threonine kinase or a receptor tyrosine kinase.
摘要:
