Hybridization of the variable number of tandem repeat core oligonucleotide GNNGTGGG to 350 cosmids from chromosome 7.
An efficient method using short oligonucleotides is described for the isolation of minisatellite markers of the type variable number of tandem repeats (VNTR). It is used to screen 350 cosmids from chromosome 7 for the presence of such potentially polymorphic DNA segments. From the number of hybridization signals to chromosome 7 cosmids, I estimate the human genome to have at least about 15000 VNTR loci containing minisatellite core sequences, which is well above previous estimates.
