title: Ultrasensitive enzymatic radioimmunoassay: application to detection of cholera toxin and rotavirus.
abstract: Rotavirus and enterotoxin-producing bacteria are major causes of diarrheal disease in humans. A method of rapid diagnosis, ultrasensitive enzymatic radioimmunoassay, has been developed to quantitatively detect cholera toxin and rotavirus. The method uses features of both enzyme-linked immunosorbent assay and radioimmunoassay; however, the sensitivity of the assay is 100- to 1000-fold more sensitive than the two parent assays. Ultrasensitive enzymatic radioimmunoassay should also be useful in measuring other biologically important agents such as drugs and hormones.
