Abstract: A bolus for oral administration of selenium to ruminants comprising 2% to 25% by weight of the trace mineral selenium in its elemental state and in particulate form, 70% to 97.5% by weight of an inert powdered weighting agent and, optionally, 0.25 to 5% by weight of an inert lubricant is provided.
Abstract: Probes comprise S1 and P1 nuclease (as an enzyme label) linked to a specific binding member such as a nucleotide sequence or an antibody. Such probes are useful for sandwich assays. As compared with known probes using alkaline phosphatase as a label, advantages include relative insensitivity to phosphate and elevated temperature and reduced risk of nonspecific binding.
