摘要:
The invention provides methods for amplification of polynucleotide sequences using primers containing single-stranded RNA. The methods employ use of an enzyme capable of cleaving single-stranded RNA, such as RNase I, to degrade a first RNA- containing primer prior to addition of a second RNA-containing primer. The invention also provides compositions and kits for practicing the amplification methods, as well as methods which use the amplification products.
摘要:
Methods, kits, and compositions which enable the generation of double stranded DNA products from various substrates such as low abundance RNAs or whole transcriptosomes are provided. The double stranded DNA products are suitable for downstream applications involving microarray analysis or sequencing.
摘要:
Methods of recombining nucleic acids are provided. In particular, methods for the production of partially double stranded nucleic acids comprising a 3’ overhang from an RNA target and use in methods of recombining polynucleotides is described. These methods do not require thermocycling. The present invention also provides methods of recombining and selection which allow for identification of proteins comprising improved or desired characteristics.

摘要:
The invention provides methods for linear and exponential amplification of RNA. They are particularly suitable for amplifying a plurality of RNA species in a sample. The methods are based on hybridization of polynucleotide comprising a propromoter sequence to a primer extension product to generate an intermediate polynucleotide capable of driving transcription, whereby multiple copies of RNA products comprising sequences complementary to an RNA sequence of interest are generated. The methods are useful for preparation of nucleic acid libraries and substrates for analysis of gene expression of cells in biological samples. The invention also provides compositions and kits for practicing the amplification methods, as well as methods which use the amplification products.
摘要:
The present invention provides novel methods of indirect analyte detection and quantification through amplification of oligonucleotide template attached to binding partners for analytes by nucleic acid amplification utilizing isothermal, single primer linear nucleic acid amplification methods. Methods of binding of binding partner that is attached to an oligonucleotide template to analyte, then amplifying at least a portion of the oligonucleotide template using a composite primer, primer extension, strand displacement, and optionally a termination sequence, are provided. Methods for amplifying sense RNA using a composite primer, primer extension, strand displacement, optionally template switching, a propromoter oligonucleotide and transcription are also provided. Methods for detecting and quantifying amplification products are also provided. The invention further provides compositions and kits for practicing said methods.
