Extraction and isolation of rat liver rRNAs
Rat liver was homogenized, the supernatant was centrifuged, and RNA was extracted with a mixture of phenol and m-cresol. rRNA and mRNA were separated in the pre

Synthesize 5' capped transcripts
Some RNA transcripts require an m7 G(5')Ppp(5')G cap at the 5' end, and they have higher translational efficiency only in cell-free extracts or in African Xenop
Extraction of RNA from tissues by the CsCl method
Because some tissues (e.g., pancreas and uterus) contain high concentrations of endogenous RNAases, more care must be taken in purifying tissue-derived RNA.
Extraction of RNA from cultured cells by the CsCl method
RNA preparation by guanidine thiocyanate extraction and cesium chloride centrifugation is suitable for isolation of RNA from cells with difficult separation of
RNA extraction from fresh and frozen blood
Whole blood contains nucleated leukocytes, so it is easy to extract RNA from blood, but red blood cells are rich in ribonuclease, so it is difficult to isolate
RNA extraction from formalin-fixed, paraffin-embedded tissues
Formalin-fixed, paraffin-embedded tissues from the pathology department can be used for RNA expression analysis. RNA isolated from biopsy, surgical, and cadaver
Nuclease cleaves RNA at a specific site
Nuclease is a useful tool for obtaining site-specific cleavage products of long fragments of RNA for the study of RNA modification, for modification site analys
RNA radiolabeling
Intramolecular labeling of RNA during transcription, post-transcriptional labeling of the 5' end of RNA using T4 polynucleotide kinase and labeling of the 3' en
RNA reverse transcription
The RNA template is used to obtain DNA by reverse transcription, which is then used to replicate and infect cells.
