classified by comparing the computed combination of labels to a table of standard
labeling based on the known combinations of the five fluorophores used in the
sample preparation. The classification results are displayed in Fig. 13.9b, in which
each color represents a different chromosome type. This approach results in
accurate classification with high specificity in the vast majority of specimens,
even on complex samples [50, 51]. Similar applications, called spectral karyotyping
(SKY) and COBRA-FISH, also use spectral unmixing [28, 52]. Various
other applications have been enabled by this technique as well, both for
immunofluorescence detection and elim ...
