Abstract

In an attempt to apply immunomorphologic techniques to formalin-fixed material, various tissues were studied by indirect immunofluorescence. To minimize nonspecific background staining, formalin-fixed paraffin sections were treated with pronase prior to incubation with the antisera. This technique was published by Huang in 1975 to study hepatitis B core and surface antigen in formalin-fixed liver-tissue.

Our examination demonstrate that this technique might enable the morphologist to identify immunoglobulins in formalin-fixed tissues and so to get new criteria for their diagnosis.

福尔马林固定和石蜡包埋材料的免疫荧光研究
为了尝试将免疫形态学技术应用于福尔马林固定材料,采用间接免疫荧光法对不同组织进行了研究。为了减少非特异性背景染色,在与抗血清孵育之前,用pronase处理福尔马林固定石蜡切片。该技术于1975年由Huang发表,用于研究福尔马林固定肝组织中的乙型肝炎核心和表面抗原。我们的研究表明,这种技术可能使形态学家识别免疫球蛋白在福尔马林固定组织,从而获得新的诊断标准。
