ABSTRACT
【Objective】To establish a simple method for preparing tissue chip.【Methods】One hundred and thirty mammary cancer and intestinal cancer specimens were fixed by formaldehyde(40?g/L) and embedded by wax,and then were made into routine tissue slices and stained by haematoxylin and eosin(HE).Wax slices with tissue chip were prepared by fixing a tissue slice(0.1 cm in diameter)into the hole(0.2 cm in diameter and 2~4mm in depth) of a blank wax slice and were sliced into 4?m-thick slices.The tissue chips were mounted on the slide and stained by immunohistochemistry after treatment.【Results】A slide held 45 tissue chips and 130 specimens could be all detected only on 3 slides,which saved time and the amount of reagent.The immunohistochemical results showed that the positive location was accurate and the background was clear.【Conclusion】This method for preparing tissue chip is simple and effective,and can save the amount of reagent.It is easy for the comparative and separated detection of specimens.
