20100018862 | CELLOMICS SYSTEM - In labeling a cell, and separating and collecting the cell according to a degree of the labeling using a cell separator, effects on the cell is minimized and the use of the collected cell is facilitated, thereby, when labeling a cell, the cell is labeled in the state where interaction of each cell is retained. In the labeling, a specific labeling material present on a surface of a target cell is taken in the cell via a transporter, and the cell is dispersed one by one to separate the same with a cell separator. Immediately after the separation, the cell is put in a solution not containing the specific labeling substance to remove the specific labeling substance taken in the cell. This series of steps is continuously conducted with a cell separation chip. | 01-28-2010 |
20110011742 | METHOD FOR THE PURIFICATION OF BIOLOGICAL MACROMOLECULES - Disclosed are methods and devices for electrophoretic separation of free biomolecules from molecular complexes comprising biomolecules of interest during which inhomogeneity in the molecular complexes is masked. The methods can include loading a sample which contains free biomolecules and the complexes that include biomolecules of interest to a proximal end of an electrophoresis gel. The sample is electrophoresed for a period of time sufficient for the free biomolecules to elute off a distal end of the gel while the molecular complexes that include the biomolecules of interest are retained in the electrophoresis gel, thereby separating the molecular complexes from the free biomolecules. The direction of electrophoresis is reversed and the sample is electrophoresed for a period of time sufficient for the molecular complexes of bound biomolecules of interest to elute from the proximal end of the electrophoresis gel. | 01-20-2011 |
