摘要:
A spin-trapping assay for nitric oxide, in a biological system such as whole blood, uses as the spin trap a lipid-soluble nitrobenzene compound such as 2,6-dimethylnitrosobenzene.
摘要:
A solid state device for performing multi-analyte assays, comprises a substrate and a multiplicity of discrete reaction sites each bearing a ligand covalently bonded to the substrate, wherein the surface of the substrate between the reaction sites is inert with respect to analyte. Such a device may be obtained by a process of activating the surface of the substrate, and applying an array of ligands on to discrete areas on the surface.
摘要:
An assay for an analyte in a sample, wherein the sample is contacted with an array of ligands including a ligand specific for the analyte, additionally comprises including a scavenger material that binds the analyte and thereby reduces its available concentration.
