After collecting biological materials, it is best to be able to perform RNA preparation immediately. If temporary storage is required, the biological materials should be frozen quickly with liquid nitrogen and then stored in a freezer at -80 Â° C. When preparing RNA, remove the materials stored in the freezer and immediately break the cells by adding liquid nitrogen to grind them. It is not allowed to thaw first to avoid the effect of RNase.
