Problem 1) Why do you think that it's so important in a histochemical microscopic procedure to have very thin sections?
Problem 2) What do you conclude about the expression of alkaline phosphatase in these 2 tissues? Is alkaline phosphatase expressed in all tissues? In equal amounts?
Problem 3) Are there any problems that might make one tissue more difficult to examine than another?
Problem 4) Why do you think the enzyme is expressed in the cells that it is?
Problem 5) Is the expression of the enzyme localized in any particular areas of the tissues? Is it all over? How can you tell?
