在石蜡切片的免疫组化染色中 ,常因被检测的抗原遭到甲醛等常用固定剂的破坏而影响到免疫组化染色效果 ,为此 ,人们一方面通过对石蜡切片进行酶消化或热处理使免疫组化检测敏感性提高 ,另一方面通过提高检测系统的敏感性来克服这一限制。催化信号放大 (ｃａｔａｌｙｚｅｄｓｉ?
In immunohistochemical staining of paraffin sections, the antigens to be detected are often affected by the destruction of commonly used fixatives such as formaldehyde to influence the immunohistochemical staining effect. For this reason, on the one hand, paraffin sections are subjected to enzymatic digestion or heat treatment. The sensitivity of immunohistochemical detection is improved. On the other hand, this limit is overcome by increasing the sensitivity of the detection system. Catalytic signal amplification (catalyzedsi?
