Patent CA-2495206-C (CA)
Title: Membrane-based assays using time-resolved fluorescence
Inventor: SONG XUEDONG
IPC: G01N33/58
Filed: 2003-07-10
Granted: 2012-10-30
Abstract: A membrane-based assay device for detecting the presence or quantity of an analyte residing in a test sample is provided. The device utilizes time-resolved fluorescence to detect the signals generated by excited fluorescent labels. Because the labels can have relatively long emission lifetime, short-lived background interference can be practically eliminated through delayed fluorescence detection. In addition, the resulting fluorescent reader can have a simple and inexpensive design. For instance, in one embodiment, the reader can utilize a silicon photodiodide and a pulsed light-emitting diode (LED) to accurately excite labels and detect fluorescence on a membrane-based assay device without requiring the use of expensive components, such as monochromators or narrow emission band width optical filters.

Granted: 2012-04-10
Abstract: The invention relates to the stem cells, embryonic stem cells in particular.  It has been found that, when these stem cells are entrapped such that their proliferation is inhibited, they produce material which inhibits the proliferation of other, non-entrapped cells, including stem cells and neoplastic and/or hyperproliferative, but otherwise normal cells. It has also been found that entrapped cancer cells will produce material which inhibits the proliferation of stem cells. Further, it has been found that the entrapment of the stem cells inhibits their differentiation and thus the entrapment process can serve as a long-term storage device for maintaining the undifferentiated state of at least a portion of the entrapped cells.
