Non-isotopic DNA fingerprint analyses with the minisatellite probe MZ1.3

1990

RFLP analyses with minisatellite probes yield highly informative individual specific banding patterns (genetic fingerprints) (Jeffreys et al.). Because of the complexity of the pattern and marked differences in band intensities a good band resolution and high sensitivity of the probe are essential. By reason of the latter requirement to date most of the RFLP-studies are performed with radioactive probes. Although non-isotopic labels have been introduced into fingerprint analyses (Schafer et al.; Medeiros et al.) 32P-labeled probes are still superior with respect to sensitivity. Our approach to increase the specific signal intensity makes use of an amplification of the number of probe molecu…
