Tóm tắt

AbstractFlow cytometry and sorting are now an important technology in aquatic research. Simultaneous measurements of individual particle cell size, fluorescence, and light scatter properties are directly applicable to current topics in aquatic research. Flow sorting may be employed to obtain subsets of cells for analysis by conventional methods. The manner in which rapid, precise measurements of single cells are made is complex, and the application of this technology to aquatic samples is subject to many analytical constraints. Flow cytometric measurements of algal cell size and pigment autofluorescence are relative and are therefore dependent on the optical configuration and variability of the instrument. Specific types of reference materials are used to establish the validity of analyses: (1) instrument standards, (2) fluorescence controls, and (3) internal stain standards. The selection and application of standards and controls are discussed in the context of allometric (cell size versus pigment fluorescence) and ataxonomic (pigment color groups) methods. The widespread acceptance of particular reference materials among research groups will result in comparable data sets describing aquatic particle distributions.
