A new method of the genome DNA fingerprinting based on PCR technique w
ith random primer has been developed. The method allows to reveal poly
morphism of the organization of a concrete family of moderate repeats.
The method was named SCAN because it realizes the scanning of the gen
ome as a whole. The polymorphism in organization of Ill-repeats in gen
ome of spontaneously hypertensive rats has been revealed by the method
. Apparently, there are additional copies of ID in genome of spontaneo
usly hypertensive rats compared to the closely related WKY normotensiv
e line. Linkage of the polymorphism to the phenomenon of hypertension
in spontaneously hypertensive rats is a subject of ongoing study.
