CA 2422440

The present invention provides oligonucleotide probes and oligonucleotide probe collections and protein labeling for detecting or localizing a plurality nucleic acid target genes or antigens within a cell or tissue sample. Specifically, the invention provides collections of oligonucleotide probes for use in in situ hybridization analyses in which each probe has a label-domain with the sequence formulas of (CTATTTT)n CT, (AAAATAG)n or (TTTTATC)n or (GATAAAA)n in which all cases "n" would equal 1 or greater. The present invention provides collections or "cocktails" of oligonucleotide probes for detecting or localizing specific nucleic acid target genes within a cell or tissue sample. The cocktails are useful for detecting the following: the Kappa gene (SEQ ID NOS: 1-16 inclusive); the Lamba gene (SEQ ID NOS: 17 through 29 inclusive); the CMV (cytomegalovirus) gene (SEQ ID NOS: 30 through 50 inclusive); EBER (Epstein- Barr early RNA) gene (SEQ ID NOS: 51-54 inclusive): Alu (SEQ ID NOS: 55-56); PolyA (SEQ ID NO: 57); and the detection tail (SEQ ID NO: 58).

L'invention concerne des sondes oligonucléotidiques et des collections de sondes oligonucléotidiques et le marquage de protéines pour la détection et la localisation de plusieurs gènes ou antigènes cibles d'acides nucléiques à l'intérieur d'une cellule ou d'un échantillon tissulaire. Plus spécialement, l'invention concerne des collections de sondes oligonucléotidiques à utiliser dans des analyses d'hybridation in situ dans lesquelles chaque sonde comporte un domaine de marquage présentant les formules de séquence (CTATTTT)¿n?, (AAAATAG)¿n? ou (TTTTATC)¿n? ou (GATAAAA)¿n?, n étant dans tous les cas supérieur ou égal à 1. L'invention concerne des collections ou des <= cocktails >= de sondes oligonucléotidiques pour la détection ou la localisation de gènes cibles spécifiques d'acides nucléiques à l'intérieur d'une cellule ou d'un échantillon tissulaire. Les cocktails sont utiles pour détecter le gène Kappa (SEQ ID NOS : 1-16 inclus), le gène Lamba (SEQ ID NOS : 501-509, 511-513 et 515), le gène CMV (cytomégalovirus) (SEQ ID NOS : 221-241 inclus), le gène EBER (ARN précoce d'Epstein-Barr) (SEQ ID NOS : 51-54 inclus), Alu (SEQ ID NOS : 55-56), PolyA (SEQ ID NOS : 57), et la queue de détection (SEQ ID NOS : 330).
