随着医学科学研究的不断发展,实验动物的品质要求越来越高,肿瘤研究迫切需要SPF动物。我们采用超净生物层流架(简称层流架),小规模、低投入,饲育NC裸小鼠,满足了本所裸小鼠人大肠癌传代模型等研究的需要。本文总结了二年多来(自1989年11月起)层流架的使用效果,并对日常维 With the continuous development of medical science research, the quality requirements of experimental animals are getting higher and higher, and tumor research urgently needs SPF animals. We use ultra-clean biological laminar flow shelves (referred to as laminar flow shelves), small-scale, low-input, breeding of NC nude mice, to meet the needs of the research on the colorectal cancer subculture model of nude mice. This article summarizes the use of laminar flow shelves for more than two years (since November 1989) and
