The correct name of the method is guanidinium thiocyanate-phenol-chloroform extraction. The use of TRIzol can result in DNA yields comparable to other extraction methods, and it leads to >50% bigger RNA yield. [5] [6] An alternative method for RNA extraction is phenol extraction and TCA/acetone precipitation. Chloroform should be exchanged with ...
The RNA is then precipitated in an alcohol (right). Acid guanidinium thiocyanate-phenol-chloroform extraction (abbreviated AGPC) is a liquid–liquid extraction technique in biochemistry and molecular biology. It is widely used for isolating RNA (as well as DNA and protein in some cases).
Several methods are used in molecular biology to isolate RNA from samples, the most common of these is guanidinium thiocyanate-phenol-chloroform extraction. [2] [3]. Usually, the phenol-chloroform solution used for RNA extraction has lower pH, this aids in separating DNA from RNA and leads to a more pure RNA preparation.

Aqueous samples, lysed cells, or homogenised tissue are mixed with equal volumes of a phenol:chloroform mixture. This mixture is then centrifuged. Because the phenol:chloroform mixture is immiscible with water, the centrifuge will cause two distinct phases to form: an upper aqueous phase, and a lower organic phase.
A general blotting procedure [5] starts with extraction of total RNA from a homogenized tissue sample or from cells. Eukaryotic mRNA can then be isolated through the use of oligo (dT) cellulose chromatography to isolate only those RNAs with a poly(A) tail. [8] [9] RNA samples are then separated by gel electrophoresis. Since the gels are fragile ...
RNA-Seq refers to the combination of a high-throughput sequencing methodology with computational methods to capture and quantify transcripts present in an RNA extract. [10] The nucleotide sequences generated are typically around 100 bp in length, but can range from 30 bp to over 10,000 bp depending on the sequencing method used.
