RNA Purification Protocol for 100-200 mg of Animal Tissue

. Storage at -70°C. Fresh tissue can also be used. Work quickly and keep the sample on ice at all times. 2. Add 100-200 mg frozen ground tissue or fresh tissue to a 15 mL centrifuge tube containing 6 ml RCL Buffer. Homogenize the sample using 5-10

转运RNA(tRNA)

佚名     tRNA(transfer RNA)是蛋白质合成中的接合器分子。tRNA分子有100多种，各可携带一种氨基酸，将其转运到核蛋白体上，供蛋白质合成使用。tRNA是细胞内分子量最小的一类核酸，由70～120核苷酸构成，各种tRNA无论在一级结构上，还是在二、三级结构上均有一些共同特点。tRNA中含有10%～20%的稀有碱基(rare bases)，如：甲基
