Tissue	Tonsil	Liver	Liver
Description	All B- and T-cells must show a moderate to strong, distinct predominantly membranous staining reaction.	Virtually all Kupffer cells must show an at least weak to moderate predominantly membranous staining reaction. Note lymphocytes will show strong staining reaction and cannot be used to evaluate analytical sensitivity.	No staining reaction in hepatocytes and epithelial cells of bile ducts.
