    Abstract: Methods and kits for labeling nucleic acids are provided. In the subject methods, an oligonucleotide tagged nucleic acid comprising an oligonucleotide tag is first generated. The oligonucleotide tagged nucleic acid is then contacted under hybridization conditions with a labeled oligonucleotide complementary to the oligonucleotide tag, yielding a labeled nucleic acid. The kits of the subject invention at least include a primer for use in enzymatically generating an oligonucleotide tagged target nucleic acid, where the primer generally at least includes an oligo dT region and the oligonucleotide tag, and a labeled oligonucleotide complementary to the oligonucleotide tag. The subject methods and kits find use in a variety of applications, and are particularly suited for use in gene expression analysis applications.

    Abstract: The present invention relates to two primers for amplifying a cytomegalovirus (CMV) nucleic acid suitable for a nucleic acid sequence-based amplification (NASBA) using a DNA-dependent RNA polymerase, a first primer containing a promoter sequence and a nucleic acid sequence consisting of at least fifteen continuous bases selected from the nucleic acid sequence of SEQ ID NO:1; a second primer containing a nucleic acid sequence consisting of at least fifteen continuous bases selected from the nucleic acid sequence of SEQ ID NO:2, NO:3 or NO:4; a detecting probe and/or a capturing probe containing a nucleic acid sequence consisting of at least continuous fifteen bases selected from the nucleic acid sequence(s) of SEQ ID NO:5, NO:6 and/or NO:7 wherein said sequence is modified if necessary; a reagent kit for detecting a CMV containing the above-mentioned primers and probes; and a nucleic acid sequence-based amplification (NASBA) using said primers. The advantages of the present invention are that CMV can be detected in an easy, rapid and specific manner with a high sensitivity.

    Abstract: This invention provides methods for characterizing the amounts of nucleic acids, including plus/minus determinations, the use of different constructs, the use of a library and a reference library. Expression may also be compared in two or more samples using the methods of this invention. Also provided are heterophasic arrays comprising labeled positive copies of nucleic acids hybridized to the array and labeled negative copies of nucleic acids hybridized to the array, in which the labeled positive copies are separately quantifiable from the labeled negative copies.

    Abstract: The present invention provides a method for performing a localised RCA reaction comprising at least two rounds of RCA, wherein the product of a second RCA reaction is attached, and hence localised, to a product of a first RCA reaction, said method comprising: (a) providing a concatemeric first RCA product comprising repeated monomers; (b) directly or indirectly hybridising to monomers of said first RCA product a circularisable oligonucleotide comprising target-complementary 3′ and 5′ end regions such that the 3′ and 5′ ends of said oligonucleotide hybridise in juxtaposition for ligation directly or indirectly to each other, wherein the target is a sequence in a monomer of said first RCA product or an intermediate molecule hybridised thereto, and wherein the target-complementary end regions of said circularisable oligonucleotide are 6 to 16 nucleotides in length; (c) directly or indirectly ligating the ends of said circularisable oligonucleotide to circularise the oligonucleotide, thereby to provide a template for a second RCA reaction, wherein when said ends are indirectly ligated (i) either a gap oligonucleotide is provided which hybridises to the monomers of the first RCA product in between the 3′ and 5′ ends of the circularisable oligonucleotide such that it may be ligated to the respective ends, or the hybridised 3′ end of the circularisable oligonucleotide is extended by a polymerase such that the extended 3′ end may be ligated to the hybridised 5′ end, and (ii) the total length of the region of the second RCA template directly or indirectly hybridised to the monomers is no longer than 32 nucleotides in length; and (d) performing a second RCA reaction using said second RCA template of (c) and a primer for said second RCA, to form a second RCA product, wherein in said second RCA reaction the second RCA template remains attached to the first RCA product, and thereby the second RCA product is attached to the first RCA product.
