2.2 In general, the method is performed using an extract of a soil sample. Filtered extracts
may be stored cold, in the dark. An aliquot of the extract and an enzyme-toxaphene conjugate
reagent are added to an immobilized toxaphene antibody. The enzyme-toxaphene conjugate
"competes" with toxaphene present in the sample for binding to the immobilized toxaphene antibody.
The enzyme-toxaphene conjugate bound to the toxaphene antibody then catalyzes a colorless
substrate to a colored product. The test is interpreted by comparing the color produced by a sample
to the response produced by a reference reaction.详细>
