CD31 can be detected using various laboratory techniques, with immunohistochemistry (IHC) and flow cytometry being the most common. In IHC, antibodies specific to CD31 are used to stain tissue sections, highlighting endothelial cells and their structures. This technique is valuable for studying the architecture of blood vessels in normal and pathological tissues. In flow cytometry, CD31 antibodies can help identify and quantify endothelial cells in a mixed cell population.
