Measurement of nucleoside kinases in crude tissue extracts
(Elsevier, 1983-08)
The measurements of deoxyadenosine kinase, adenosine kinase, and deoxycytidine kinase were examined in human placental cytosol to achieve a valid and reliable assay linear with time and protein. Our studies confirm the ...
Antibody-antigen complex formation with immobilized immunoglobulins
(Elsevier, 1992-08-15)
We have investigated the complex formation between an immobilized monoclonal antibody and antigens that differ in size about 50-fold. As a model system, we used an iodinated progesterone derivative and a progesterone-horseradish ...
An N-acetyl--glucosamine binding lectin from Bandeiraea Simplicifolia seeds
(Elsevier, 1976-11)
A second lectin with a high activity for nonreducing 2-acetamido-2-deoxy-[alpha]--glucopyranosyl residues has been isolated from the seed extracts of Bandeiraea simplicifolia by affinity chromatography on chitin. The lectin ...
Radiometric assay for direct quantitation of rat liver cytochrome P-450b using monoclonal antibodies
(Elsevier, 1985-08-15)
A simple and sensitive assay has been developed that is capable of detecting as little as 0.2 ng of the major isozyme of cytochrome P-450 (P-450b) isolated from the livers of phenobarbital-induced rats. This assay employs ...
Carbohydrate-binding specificity of the daffodil (Narcissus pseudonarcissus) and amaryllis (Hippeastrum hybr.) bulb lectins
(Elsevier, 1990-06)
The carbohydrate binding specificity of the daffodil (Narcissus pseudonarcissus; NPA) and amaryllis (Hippeastrum hybr.; HHA) lectins, isolated from extracts of their bulbs by affinity chromatography on immobilized mannose, ...
Protein-carbohydrate interaction : V. Further inhibition studies directed toward defining the stereochemical requirements of the reactive sites of concanavalin A
(Elsevier, 1967-07)
Inhibition studies on the concanavalin A-dextran interaction have been extended using as inhibitors the members of the maltose-, isomaltose-, and methyl [alpha]-isomaltoside series, amino and N-acetyl amino sugars, and a ...
Cumene hydroperoxide-supported denitrification of 2-nitropropane in uninduced mouse liver microsomes
(Elsevier, 1986)
1. 1. Cumene hydroperoxide supported oxidative denitrification of 2-nitropropane was investigated in uninduced mouse liver microsomes.2. 2. The cytochrome P-450 peroxygenase catalyzed reaction resulted in the production ...
Attachment of Reporter and Conjugate Groups to the 3′ Termini of Oligonucleotides
(Wiley Periodicals, Inc.Humana Press, 2000-10)
Conjugation of oligonucleotides at the 3 terminus is less common because this site is used for covalent linkage to solid‐phase oligonucleotide synthesis supports. However, 3‐oligonucleotide conjugates have several valuable ...
