近几年来,用还原型辅酶II钠盐(NADPH-d)组织化学方法显示一氧化氮合酶(NOS)在各种组织中的分布文献报道很多,这种方法只能间接显示NOS在组织中的分布,而不能直接显示NOS各亚型在组织中的表达。应用NOS各亚型的抗体进行免疫细胞化学反应可在组织内直接显示NOS各亚型的表达,目前 In recent years, the use of reduced coenzyme II sodium salt (NADPH-d) histochemical method shows the distribution of nitric oxide synthase (NOS) in various tissues reported in many literature, this method can only indirectly show the NOS in the tissue The distribution of NOS can not directly show the expression of NOS subtypes in the tissue. Application of NOS subtypes of antibodies for immunocytochemical reactions can be directly displayed in the organization of NOS subtypes of the expression of the current
