凡进行病理检验的各种组织都需要进行固定,固定可使组织、细胞内的物质尽量接近其生活状态时的形态结构和位置。而免疫组化标记对组织固定提出了更高的要求,检测组织要求必须取材新鲜、固定及时,这样不仅可保存组织细胞形态结构的完整,而且可保留组织细胞的抗原性。因此,固定液 Where the pathological examination of various organizations need to be fixed, fixed tissue, intracellular material as close as possible to the morphological structure and location of their living conditions. The immunohistochemical markers put forward higher requirements for tissue fixation, testing organizations must be drawn fresh, fixed and timely, so that not only can save the integrity of the morphological structure of tissue cells, and can retain the antigenicity of tissue cells. Therefore, fixative
