我们开发了一种用于免疫组织化学研究的方法,将组织固定与缓冲的中性福尔马林和聚酯蜡包埋相结合。中性福尔马林缓冲固定保存了细胞和组织的精细结构,也保护了不稳定酶的抗原性。聚酯蜡包埋使各种组织的薄层连续切片成为可能,并将抗原性保存至少6个月。我们用这种技术证明了α-淀粉酶在小鼠唾液腺中的定位,壁细胞特异性抗原在小鼠腺胃中的定位,以及DNA聚合酶α和β在鸡组织中的定位。
We have developed a method useful for immunohistochemical studies by combining tissue fixation with buffered neutral formalin and polyester wax embedding. Buffered neutral formalin fixation preserves cell and tissue fine structure, and also the antigenicity of unstable enzymes. Polyester wax embedding makes possible thin serial sections of various tissues and preserves antigenicities for at least 6 months. We have demonstrated using this technique the localization of alpha-amylase in mouse salivary gland, parietal-cell specific antigen in mouse glandular stomach, and DNA polymerase alpha and beta in chick tissue.
