Abstract:
The present invention provides, among other things, methods of quantitating mRNA capping efficiency, particularly for mRNA synthesized in vitro. In some embodiments, the methods comprise chromatographic methods of quantifying capping efficiency and methylation status of the caps.
Abstract:
Provided herein are methods and compositions to extract and enrich by, physical separation or amplification, relatively short nucleic acids from a nucleic acid composition containing a high background of longer nucleic acids (e.g., host or maternal nucleic acids; genomic nucleic acid and the like).
Abstract:
Point-of-care binding assays include at least one target nucleic acid binding in a multiplex structure with at least one sequence in a partner nucleic acid associated with a label, due to complementary base pairings between at least one sequence in the target nucleic acid and at least one sequence in the partner nucleic acid. The assays overcome the inherent deficiencies of antibody-protein antigen assays. In a preferred embodiment, color tagged nucleic acid sequences are used to bind a complementary target nucleic acid. The tagged nucleic acid sequences are preferably made from deoxyribonucleotides, ribonucleotides, or peptide nucleotides.
Abstract:
In accordance with the present invention, there is provided a new method for detection and quantification of virus and viral particles, comprising the step of labeling the nucleic acids of an intact virus or viral particle with a dye that emits fluorescence once complexed with the nucleic acids and detecting the virus or viral particle with a chromatograph equipped with a fluorescence detector.
Abstract:
The present invention is directed to methods and compositions for the use of electron transfer moieties with different redox potentials to electronically detect nucleic acids, particularly for the electrochemical sequencing of DNA.
Abstract:
The present invention relates to improvements in methods of DNA mutation detection using chromatographic methods such as DHPLC. In particular, the invention relates to methods for increasing the level of heteroduplex during a hybridization process between a DNA fragment and a corresponding wild type DNA fragment by including during the hybridization process nitrogen-containing organic compounds such as betaine, trimethylamine N-oxide, and dimethylglycine. In another aspect the inventino provides improved PCR primers for amplifying the DNA to be used in the hybridization. The invention also provides for DNA hybridization kits containing these compounds and primers.
