Detection of DNA sequences in Plasmodium berghei by means of in situ hybridization.
A non-radioactive in situ hybridization technique, used to map unique DNA sequences to plant chromosomes, has been adapted for the localization of specific DNA sequences in nuclei of Plasmodium berghei. After hybridization using probes labeled with biotin-11-dUTP, the formed DNA/DNA hybrids were detected by fluorescence microscopy using a specific double-layer antibody technique. Besides its high resolution, this procedure is characterized by a high sensitivity, allowing the detection of a unique sequence as small as 2.5 kb.
