Motilin release in the pig.
Motilin is found in the upper intestine of pig and man and in man is released by acid. A similar release by acid has now been found in the pig and is associated with markedly reduced immunostainable motilin in the upper small intestine. Clamping the arteries and veins to the stimulated segment immediately reversed the rise of plasma motilin, indicating the motilin release to be an entirely loca...
متن کاملA radioimmunoassay for isoniazid.
A sensitive radioimmunoassay is described, for measuring isoniazid in therapeutic and subtherapeutic concentrations. This radioimmunoassay was used in an exploratory clinical study to measure, as a function of time, the concentration of this drug in plasma of patients receiving isoniazid therapy.
متن کاملRadioimmunoassay for human prothrombin.
I describe a radioimmunoassay for human prothrombin, with use of a double-antibody technique. Antiserum raised in rabbits was absorbed with Al(OH)3 and heated to 56 degrees C for 30 min. 125I-labeled prothrombin retaining more than 90% of its biological activity was prepared by the iodine monochloride method. The mean concentration of prothrombin in plasma of 12 normal individuals was 100 +/- 2...
متن کاملRadioimmunoassay for Cyclic Nucleotides
Sensitive and specific radioimmunoassays have been developed for cyclic adenosine 3’, 5’-monophosphate (CAMP), cyclic guanosine 3’ ,5’-monophosphate (cGMP), cyclic inosine 3’ ,5’-monophosphate (cIMP), and cyclic uridine 3’, 5’monophosphate (cUMP). These assays are based upon competition of the cyclic nucleotide with isotopically labeled cyclic nucleotide derivatives for binding sites on specifi...
متن کاملRadioimmunoassay for serum myoglobin.
A column flow-through radioimmune assay for serum myoglobin has been developed. The assay uses antibodies to human or rhesus monkey myoglobin coupled to Sepharose by cyanogen bromide activation and myoglobin labeled by the Chloramine-T method. The labeled myoglobin is stable over two to three half-lives. Serum myoglobin levels were elevated when serum was taken up to 12 hours after myocardial i...
