Abstract
Abstract Oligonucleotide probes reactive with regions of neu oncogenes of mammalian origin in which the mutation causing activation of such oncogenes is contained are described, as are methods for their use in detecting the presence of neu oncogenes in tumor cells. Antibodies specific for gene products encoded by neu oncogenes are also described.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
40 words
An oligonucleotide probe capable of hybridizing specifically with the region of mutational activation in a neu gene of mammalian origin, the region of mutational activation being within that portion of the gene encoding the transmembrane domain of the gene product.
Claim 2
Dependent Claim
40 words
An oligonucleotide probe capable of hybridizing specifically with the region of mutational activation in a neu gene of mammalian origin, the region of mutational activation being within that portion of the gene encoding the transmembrane domain of the gene product.
Claim 3
Dependent Claim
9 words
An oligonucleotide probe of claim 1 which is labelled.
Claim 4
Dependent Claim
9 words
An oligonucleotide probe of claim 2 which is radiolabelled.
Claim 5
Dependent Claim
57 words
An oligonucleotide probe which is capable of hybridizing specifically with a nucleotide sequence present in a region of a neu oncogene of mammalian origin but not present in the corresponding region of the protooncogene for that neu oncogene, said region of the oncogene and the protooncogene being that region encoding the transmembrane domain of the gene product.
Claim 6
Dependent Claim
57 words
An oligonucleotide probe which is capable of hybridizing specifically with a nucleotide sequence present in a region of a neu oncogene of mammalian origin but not present in the corresponding region of the protooncogene for that neu oncogene, said region of the oncogene and the protooncogene being that region encoding the transmembrane domain of the gene product.
Claim 7
Dependent Claim
9 words
An oligonucleotide probe of claim 4 which is labelled.
Claim 8
Dependent Claim
9 words
An oligonucleotide probe of claim 5 which is radiolabelled.
Claim 9
Dependent Claim
68 words
An oligonucleotide probe comprising from 15 to 20 nucleotides, the probe being capable of hybridizing specifically with a region of a neu oncogene of mammalian origin which differs from the corresponding of the protooncogene of said oncogene by a single nucleotide substitution, said substitution causing activation of the neu oncogene, and said region being within that portion of the gene encoding the transmembrane domain of the gene product.
Claim 10
Dependent Claim
68 words
An oligonucleotide probe comprising from 15 to 20 nucleotides, the probe being capable of hybridizing specifically with a region of a neu oncogene of mammalian origin which differs from the corresponding of the protooncogene of said oncogene by a single nucleotide substitution, said substitution causing activation of the neu oncogene, and said region being within that portion of the gene encoding the transmembrane domain of the gene product.
