Scientists want to find out where a protein called Z is found inside liver cells. They make a monoclonal antibody that binds to protein Z and attach a fluorescent dye to it. The antibody is added to a thin slice of liver tissue. The tissue is then washed and viewed using a microscope.
Explain why the antibody used must be monoclonal rather than a mixture of different antibodies.
Explain why the tissue is washed before it is viewed.
Protein Z is found in the cell membranes. Give what the scientists will see using the microscope.
