RNA Extraction (Column)

The RNA in cells can be divided into messenger RNA (mRNA), transport RNA
(tRNA) and ribosomal RNA (rRNA). The contents of various
RNAs are different, among which rRNA accounts for 80%-85% of total RNA
content in cells; tRNA accounts for 10-15% of total RNA, and acts as the carrier
of amino acid transportation; mRNA accounts for 1-5% of total RNA, and is the
codons for amino acid translation. The process of total RNA extraction from
different tissues contains lysing cells, releasing RNA, and removing impurities
such as proteins and DNA in different ways to finally obtain high-purity RNA
