Technique
- Combine a sample suspected of containing the drug of interest with a solution containing a known concentration of antibody and the enzyme substrate.
- After a short period (usually less than a minute) to allow binding, add a known concentration of the conjugate.
- Measure the rate of appearance of color or fluorescence.
- Determine the drug concentration by comparing the observed rate to the rates produced by known concentrations of the drug.

Famous quotes containing the word technique:
“Every notable advance in technique or organization has to be paid for, and in most cases the debit is more or less equivalent to the credit. Except of course when it’s more than equivalent, as it has been with universal education, for example, or wireless, or these damned aeroplanes. In which case, of course, your progress is a step backwards and downwards.”
—Aldous Huxley (1894–1963)
“Irony in writing is a technique for increasing reader self- approval.”
—Jessamyn West (1907–1984)
“The audience is the most revered member of the theater. Without an audience there is no theater. Every technique learned by the actor, every curtain, every flat on the stage, every careful analysis by the director, every coordinated scene, is for the enjoyment of the audience. They are our guests, our evaluators, and the last spoke in the wheel which can then begin to roll. They make the performance meaningful.”
—Viola Spolin (b. 1911)
