[An improved method for the determination of Y chromosomes in blood stains (author's transl)].
A new filter combination for fluorescence microscopy using SWP 440 interfernece filter for excitation and GG 455 as the barrier filter is described. In blind trials examining blood smears of 5 male persons and by examination of 3 weeks old blood stains a better Y chromosome demonstration has been obtained using this new technique in comparison with the "usual" filter combination: BG 12-530. In blind trials of up to 6 weeks old blood stains of one male and one female a reliable sex determination was made using the new technique.
