Solid‐Phase Synthesis of Branched Oligonucleotides
(Wiley Periodicals, Inc.Academic Press, 2002-06)
Branched nucleic acids (bNAs) have been of particular interest since the discovery of RNA forks and lariats as intermediates of nuclear mRNA splicing, as well as multicopy, single‐stranded DNA (msDNA). Such molecules contain ...
High-performance liquid chromatographic determination of ibuprofen and its major metabolites in biological fluids
(Elsevier, 1982-11-12)
A sensitive and selective high-performance liquid-chromatographic assay for ibuprofen and its major metabolites in biological fluids is described. To ensure good chromatographic separation the drug and metabolites were run ...
Chemical and Enzymatic Methods for Preparing Circular Single‐Stranded DNAs
(CRC PressWiley Periodicals, Inc., 2000-02)
Small circular oligonucleotides can be used for diagnostic, therapeutic, and laboratory purposes. These systems have gained considerable attention in recent years because they form unusually strong and specific complexes ...
Determination of the glucosidase-stimulating proteins by competitive enzyme-linked immunoassay
(Elsevier, 1984-10)
A procedure for the immunoassay of cohydrolase sphingolipid-I in mouse tissue is described. This cohydrolase (actually a mixture of at least four related proteins) stimulates or activates the [beta]-glucosidase which ...
3′‐Modified Oligonucleotides and their Conjugates
(Wiley Periodicals, Inc.Pierce Chemical Company, 2000-12)
Solid‐phase synthesis of 3′‐aminoalkyl, 3′‐thioalkyl, and 3′‐polyethyleneglycol are described. The first two are important as specific points of attachment for a large variety of reporter groups; the latter is important ...
The destruction of indoleacetic acid. III. Relationships between peroxidase action and indoleacetic acid oxidation
(Elsevier, 1960-03)
The indoleacetic acid (IAA)-oxidizing enzyme preparation from Omphalia flavida exhibits peroxidase activity on pyrogallol with an optimum at pH 3.5-3.7, like that for the IAA-oxidizing activity. It shows no polyphenolase ...
Immunocytochemistry of sequence-related neuropeptides in Drosophila
(Elsevier, 1993-06)
Based on structure, activity, and expression, the Drosophila drosulfakinin I peptide (DSK I; FDDY(OSO3H)GHMRFamide) is similar to the vertebrate peptide, cholecystokinin.1 Dromyosuppressin (DMS; TDVDHVFLRFamide) is an ...
Manganous chloride spray reagent for cholesterol and bile acids on thin-layer chromatograms
(Elsevier, 1970-12-02)
