【Abstract】 The RNA was extracted with the improved cold phenol method from rat atria. Several examinations, including ultraviolet spectrophotometric examination and electrophoresis, run in denatured agarose gel and molecular hybridization for RNA samples showed that RNA preparations had satisfactory purity and undegradation. This extraction procedure is very simple and does not need any special reagents and equipments.更多还原
