What do you mean by qualitative elisa and quantitative elisa?
Qualitative ELISA determines the presence or absence of a specific antigen or antibody in a sample. It provides a yes/no answer. Quantitative ELISA measures the amount of antigen or antibody present in a sample, providing a numerical value to indicate the concentration of the analyte.
What is the effect of not including the antigen or the primary antibody in the ELISA reaction?
If the antigen is not included in the ELISA reaction, there will be nothing for the antibodies to bind to, resulting in no signal being produced. If the primary antibody is not included, there will be no specific binding to the antigen, resulting in a false negative result.
What is the origin of elisa?
The Enzyme-Linked Immunosorbent Assay (ELISA) was developed in the 1970s as a technique to detect and quantify substances such as proteins, peptides, antibodies, and hormones. It was invented by Swedish biochemist Peter Perlmann and his colleague Eva Engvall. The ELISA method revolutionized the field of immunology and diagnostic testing.
How does the stranger interaction with elisa at her garden differ from Henry interaction with her at her garden?
The stranger seems more confident about invading her space while Henry respectfully stays outside the garden.
Why is the secondary antibody used in an ELISA test conjugated with an enzyme?
The secondary antibody in an ELISA test is conjugated with an enzyme to amplify the signal produced when the antibody binds to the target antigen. This enzyme-substrate reaction generates a detectable signal that indicates the presence of the antigen, which allows for more sensitive and accurate detection in the ELISA assay.

Why did Elisa cry like an old woman in The Chrysanthemums?
He throws her chrysanthemum sprouts onto the road.
What motivates the stranger to ask Elisa about her Chrysanthmums?
He wants to encourage Elisa to think kindly of him so she will give him some money.
Why does Elisa try not to look at what she sees in the road?
Elisa tries not to look at what she sees in the road because it is a dead snake that her husband has just run over with the car. She is upset by the violent act and feels a connection to the snake's suffering. Additionally, she is reminded of her own feelings of entrapment and powerlessness in her life.
