A comparative study of DAPI, DIPI, and Hoechst 33258 and 33342 as chromosomal DNA stains.
A comparison of four DNA stains considered to be AT-specific with chromosomes from a clonal Chinese hamster cell line B14F28-C5 have been made. The flow karyotype histograms indicate that DAPI, DIPI, and Hoechst 33258 and 33342 do stain similarly in the same preparation. DAPI staining is specific and highly reproducible in this line. We, therefore, recommend this dye as a single chromosome DNA stain for high-resolution flow cytometric measurements in cytogenetics and mutation research.
