Representative allele-specific oligonucleotide plaque hybridization for quantitation of N-ras gene mutations.
Duplicate filters hybridized with allele-specific mutant and wild-type oligonucleotide probes for N-ras codon 61. Samples: 1, normal DNA; 2, positive control—10% HL60 in normal DNA; 3 and 4, representative patient samples A and B (patients 11 and 32, Table 2).
