if a meat sample appears clear in an ELISA teat what does this result indicate?
Homework Answers
ELISA tests uses antibodies for a specific antigen that is being tested for presence and levels. If the target antigen is present in the sample, then the result will be a change in color that can be measured. But if the sample stays clear it means the target antigen/protein is not present in the sample.
So the answer is: It indicates the antigen you are testing for is not present in this meat sample.
