摘要: A method of using elongate multicellular organisms in conjunction with a specialized flow cytometer for drug discovery and compound screening. A stable, optically detectable linear marker pattern on each organism is used to construct a longitudinal map of each organism as it passes through the analysis region of the flow cytometer. This pattern is used to limit complex data analysis to particular regions of each organism thereby simplifying and speeding analysis. The longitudinal marker pattern can be used to alter signal detection modes at known regions of the organism to enhance sensitivity and overall detection effectiveness. A repeating pattern can also be used to add a synchronous element to data analysis. The marker patterns are established using known methods of molecular biology to express various indicator molecules. Inherent features of the organism can be rendered detectable to serve as marker patterns.

摘要: The high numerical aperture flow cytometer of the present invention includes a flow cell and a laser input. The laser input emits a beam of light that is oriented substantially orthoganilly to the flow of blood cells through the flow cell such that laser light impinges upon the blood cells as they pass through the flow cell. A portion of the beam from the laser input that impinges upon the blood cells in the flow cell is scattered at a substantially right angle to the beam of laser input (“right angle scatter”). A second portion of the beam from the laser input that impinges upon the cells in the flow cell is scattered at a much lower angle than 90°. This scatter is termed “low angle forward scatter light” and has an angle of from about 2° to about 5° from the orientation of the original beam from laser input. A right angle scatter light detector is oriented to receive the previously mentioned right angle scatter light. A low angle forward scatter light detector is oriented to capture the previously mentioned low angled forward scatter light oriented at about 2° to about 5° from the beam of the laser input.
