Summary:1. Field of the Invention A method for synthesizing dyes excitable by a helium-neon laser (excitable at 633 nm) from hololepidines, e. G., 7-halolepidine, which dyes are suitable for the detection and enumeration of reticulocytes in human blood samples. In another aspect, this invention provides a method for immunotyping phenocytes. The method is based on the phenomenon that when dyes of certain structure intercalate into DNA or RNA, the intensity of the dyes increases.The general structure of dyes suitable for use in this invention is shown below: wherein: R, R, R, R, R, R, R, R, R, R, R, R, R, Y, and n are as defined in the specification.
