Abstract

Alkaline phosphatase may be used as a label for immunocytochemistry and can be demonstrated in tissue sections using the single step naphthol phosphate method. Endogenous enzyme activity may not be destroyed by fixation in formalin, formol alcohol, Carnoy's or Baker's solutions and should be inhibited before results are assessed. Either Bouin's solution or periodic acid followed by potassium borohydride are satisfactory inhibitor and do not adversely affect immunocytochemical results.

摘要

碱性磷酸酶可用作免疫细胞化学的标记物,并且可以使用单步萘酚磷酸法在组织切片中显示出来。内源性酶活性不会因在福尔马林、甲醛酒精、卡诺氏液或贝克氏液中固定而被破坏,在评估结果之前应予以抑制。布因氏液或高碘酸继以硼氢化钾都是令人满意的抑制剂,且不会对免疫细胞化学结果产生不利影响。
