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

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.
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
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
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
Rapid isolation of total RNA from mammalian cells
SDS lyses the cells and extracts the total RNA by acid phenol graded extraction, which is a suitable method for treating cells with relatively low mRNA content
T4 DNA ligase ligates RNA molecules
T4 DNA Ligase joins double-stranded complexes, including RNA-DNA heteroduplexes and RNA-RNA heteroduplexes, defectively.
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
Ligation of RNA molecules with T4 RNA ligase
T4RNA ligases have been used to generate many site-specific modified RNAs, especially oligonucleotide-modified and tRNA-modified with antisense codon tRNAs.In a
