    摘要: Methods are provided for preparing a double-stranded cDNA corresponding to the 5' end of an mRNA. In the subject methods, an mRNA is first contacted with an oligo dT primer under first strand cDNA synthesis conditions. Next, the resultant hybrid is contacted with a random primer under first strand cDNA synthesis conditions, such that a cDNA complementary to the 5' end of the mRNA is produced. The resultant hybrid molecule is converted to two different double-stranded cDNAs, a first cDNA comprising the oligo dT primer and a second cDNA lacking the oligo dT primer. The two double-stranded cDNAs are then separated from each other. The subject methods find use in a variety of applications, and find particular use in the synthesis of 5' enriched cDNA libraries. Also provided are cDNA libraries produced by the subject methods, as well as kits for performing the subject methods.

    摘要: The present teachings provide methods, compositions, and kits for quantifying target, polynucleotides. In some embodiments, a reverse stem-loop ligation probe is ligated to the 3′ end of a target polynucleotide, using a ligase that can ligate the 3′ end of RNA to the 5′ end of DNA using a DNA template, such as T4 DNA ligase. Following digestion to form an elongated target polynucleotide with a liberated end, a reverse transcription reaction can be performed, followed by a PCR. In some embodiments, the methods of the present teachings can discriminate between polymorphic polynucleotides that vary by as little as one nucleotide.

    摘要: In some embodiments, the present inventions relates generally to compositions, methods and kits for use in discriminating sequence variation between different alleles. More specifically, in some embodiments, the present invention provides for compositions, methods and kits for quantitating rare (e.g., mutant) allelic variants, such as SNPs, or nucleotide (NT) insertions or deletions, in samples comprising abundant (e.g., wild type) allelic variants with high specificity and selectivity. In particular, in some embodiments, the invention relates to a highly selective method for mutation detection referred to as competitive allele-specific TaqMan PCR (“cast-PCR”).

    摘要: The invention provides new methods for screening libraries of peptides and other compounds for a desired property in eucaryotic cells. The methods are premised, in part, on the unexpected observation that the contents of procaryotic or lower eucaryotic cells, such as yeast, can be transferred to recipient eucaryotic cells in an essentially clonal manner by protoplast fusion of the respective cells. Applications of the methods include screening peptides in eucaryotic cells substantially incapable of episomal replication of transferred nucleic acid fragments; screening in eucaryotic cells peptides or secondary metabolites produced in procaryotic cells; and screening a library of peptides for capacity to bind a selected RNA in eucaryotic cells.
