RNA isolation is a crucial process in molecular biology experiments. Isolating RNA with high purity, integrity and quantity is very important for many downstream applications like qPCR, RNAi experiments, RNA sequencing and other gene expression analysis. RNA isolation with TRIzol protocol is a well-established method for isolating high-quality RNA from a variety of samples.
TRIzol reagent is a monophasic solution of phenol and guanidine isothiocyanate that facilitates the isolation of RNA, DNA and protein from the same sample. TRIzol protocol is based on the selective lysis of cells and dissociation of nucleic acids under acidic conditions. RNA selectively precipitates in the presence of guanidine isothiocyanate and a high concentration of salt, and DNA and proteins remain in the supernatant. The RNA pellet is then washed, dried and resuspended in RNase-free water or buffer.
The TRIzol protocol is a well-known and well-established method to extract high-quality RNA from different types of samples like animal tissues, plant tissues, cultured cells, bacteria, viruses and environmental samples. The protocol can be easily adapted for small-scale and large-scale RNA isolations, and it allows the extraction of different types of RNA like total RNA, mRNA, miRNA and other small RNA species. Moreover, the isolated RNA can be used for a wide range of applications like reverse transcription, PCR, qPCR, RNA sequencing and other gene expression analysis.
Magdalena Julkowska, a prominent scientist in the field of RNA isolation and plant genomics, has recently published a paper on the standard RNA isolation protocol using TRIzol. The paper provides a detailed protocol and recipe for RNA isolation with TRIzol, and also highlights some critical steps and troubleshooting tips for successful RNA isolation.
In the paper, Julkowska explains that the quality and purity of the isolated RNA depend on many factors like the type and quality of the starting material, the type and amount of TRIzol reagent used, the duration and conditions of centrifugation and the quality and purity of the final RNA pellet. Therefore, it is crucial to follow the protocol carefully and to adjust the protocol for different sample types and RNA applications.
