用常规石蜡切片方法显示碱性磷酸酶(AKP)及酸性磷酸酶(ACP),对酶活性的损失较大,定位不佳。采用恒冷箱冰冻切片机切片,虽然对酶的损失较少,但如操作不当,也易出现酶活性扩散的现象。而且此种设备价格昂贵,在一般单位不易配备。因此探讨用石蜡切片显示AKP及ACP仍然有一定的价值。 Alkaline phosphatase (AKP) and acid phosphatase (ACP) were displayed by conventional paraffin sections, which had a great loss of enzyme activity and poor localization. Frozen slicer slicing machine using constant temperature, although the loss of less enzyme, but as improper operation, but also prone to the phenomenon of proliferation of enzyme activity. And such equipment is expensive, not easy to equip in general units. Therefore, the paraffin sections to explore the AKP and ACP still have some value.
