Question

Nerissa is using immunostaining to identify different protein molecules on the cell of a pathogen. Which best describes the process that she will go through to identify the protein?
A. She will grow the cells under certain conditions to grow numerous amounts of cells.
B. She will add color dye to antibodies, and the antibodies will attach to the antigen of the pathogen.
C. She will tag parts of the DNA with chemicals that will react when DNA is turned on.
D. She will use a light microphone to identify proteins on the cell of a pathogen.

Answer 1

Answer:

She will add color dye to antibodies, and the antibodies will attach to the antigen of the pathogen.

Explanation:

Immunostaining is the process where the antibodies for a specific pathological antigen is combined with fluorescent dye or any other indicator, like enzyme. Fluorescein are common staining materials used because it is easily detectable under UV light. This antibody coated with indicator thus bind to the specific pathogen or protein and help in its identification. Also the pathogenic cell fixation is done to facilitates clear and precise identification.
