The Periodic Acid Schiff (PAS) Diastase Stain Kit is intended for use in histological demonstration of lymphocytes and mucopolysaccharides.The a-Amylase digestion step acts on glycogen to break it into smaller sugars that are then washed off the tissue section allowing visual comparison of digested and undigested slides.The PAS reaction in tissue sections is useful for the demonstration of mucopolysaccharides.PAS Positive Material: MagentaNuclei: Blue PolyTek，抗兔聚合HRP已开发，具有成本效益，可提供最清洁，最一致的染色。该系统基于聚合的过氧化物酶标记，该标记从等式中消除了生物素，从而消除了背景染色的主要原因。
