PULSED LASER FLOW CYTOMETRY

摘要

Flow cytometry comprising the steps of: producing a flow of cells of velocity (v), in single file, through an interaction region (12) of length (d), where (d) is defined by the height of a pulsed laser source (11) of height (d), which beam shines onto the flow of cells which beam defines the interaction region; pulsing the laser source at a repetition rate of (f) onto the flow of cells where the time between pulses (l/f) is approximately equal to the transit time (t) of a cell in the interaction region; collecting (15) and detecting (16) the light scattered by or fluoresced from a cell in the interaction region; analysing (17) the detected light to determine the presence or other characteristics of said cell.
