20110177489SPECIMEN IDENTIFICATION AND DISPENSATION DEVICE AND SPECIMEN IDENTIFICATION AND DISPENSATION METHOD - A specimen identification and dispensation device includes an optical measurement device which is an identification part for measuring and identifying optical information on a specimen by emitting exciting light to the specimen being a measurement target dispersed in a liquid flowing through inside of a capillary, a dispensation part for dispensing the identified specimen into wells being sections to be dispensed through a nozzle, and a concentration adjustment part which adjusts the number of the specimens contained in an aliquot solution to a desired number according to the concentration of a sample liquid and the amount of the aliquot solution. The dispensation part is movable three-dimensionally with respect to the identification part and the nozzle.07-21-2011
20110177544METHOD FOR DISTINGUISHING AND SORTING OF CELLS AND DEVICE THEREFOR - A method for distinguishing and sorting cells characterized by comprising distinguishing and sorting a specific cell mass or a part of the cells in the cell mass with the use of transmitted light data reflecting the morphological characteristics of the cells such as size and shape optionally together with side-scattering light data reflecting the characteristics of the internal structure of the cells. The part of the cells in the specific cell mass as described above are at the G1 stage or at a part of the M stage in the cell cycle. A part of the cells at the G1 stage are referred to as the left bottom line in an analytical dispersion diagram of the cells wherein the abscissa indicates the transmitted light data, while a part of the cells at the M stage are referred to as the right bottom line in the analytical dispersion diagram of the cells wherein the abscissa indicates the transmitted light data.07-21-2011
