Abstract
Official abstract text for this publication.
The present disclosure provides a reagent for blood analysis which may include: (1) a compound having the general formula I as a fluorescent dye, wherein n, X, R 1 , R 2 , R 3 , R 4 , R 5 and Y − are as defined in the specification; (2) a surfactant selected from cationic surfactants, zwitterionic surfactants and anionic surfactants. The present disclosure also provides a method to perform blood analysis including the following steps of: (a) mixing the blood sample with the reagent for blood analysis disclosed to form a cell suspension; (b) detecting the scattered light signals and fluorescence signals from the cells; and (c) differentiating and counting the cells in the blood in terms of the scattered light signals and fluorescence signals.
