A new lab technician was given the task of

preparing a new slide of earlobe for the students. She prepared and cut the

slides. But now she has to choose the appropriate staining so that the students

can observe this slide, including the cartilage and its fibers, in the best and

easiest way and to achieve the greatest contrast between elastin, connective

tissue, and epithelium. Which of the stains offered would you choose for this

slide? (figures – illustration of staining)
