How to fill out isolation of total rna

Steps to fill out isolation of total RNA:

1. Start by gathering all the necessary materials and reagents for RNA isolation, such as a sample for isolation, extraction buffer, phenol-chloroform solution, isopropanol, and ethanol.
2. Homogenize the sample using a homogenizer or by grinding it with a mortar and pestle in liquid nitrogen. This step helps in breaking down the cellular structure and releasing the RNA.
3. Add the extraction buffer to the homogenized sample, following the manufacturer's instructions. Mix the sample thoroughly to ensure proper lysis and release of RNA molecules.
4. Add the phenol-chloroform solution to the mixture and vortex it vigorously for several seconds. This step helps in separating RNA from other cellular components, such as proteins and DNA.
5. Centrifuge the mixture at high speed to separate the phases. RNA will be present in the aqueous phase, while proteins and DNA will be in the organic (phenol-chloroform) phase. Carefully transfer the aqueous phase to a new tube.
6. Add isopropanol to the aqueous phase, which precipitates the RNA. Mix gently and incubate the mixture at -20°C for at least 30 minutes to allow precipitation to occur.
7. Centrifuge the mixture again at high speed to pellet the RNA. Remove the supernatant, making sure not to disturb the pellet.
8. Wash the RNA pellet with ethanol to remove any remaining impurities. Centrifuge at high speed and carefully discard the ethanol.
9. Allow the RNA pellet to air dry for a few minutes until all the ethanol has evaporated. Take care not to overdry the pellet as it may become difficult to dissolve.
10. Finally, dissolve the RNA pellet in an appropriate volume of nuclease-free water or RNA storage solution. The RNA is now ready for downstream applications such as gene expression analysis or sequencing.

Who needs isolation of total RNA?

1. Researchers in molecular biology and genetics often need to isolate total RNA to study gene expression patterns, gene regulation, and RNA-based mechanisms.
2. Biomedical scientists studying diseases may require total RNA isolation to investigate the role of specific genes in disease progression and development.
3. Pharmaceutical and biotech companies may need to isolate total RNA to develop new therapeutic interventions, explore drug targets, or assess the safety and efficacy of potential drugs.
4. Plant biologists who study genetic engineering or plant development may also require total RNA isolation to analyze gene expression and genetic modifications in plants.
5. Forensic scientists may utilize total RNA isolation to analyze RNA evidence, such as identifying the presence of specific genes or assessing gene expression patterns for criminal investigations.

In conclusion, total RNA isolation is a crucial technique in various fields of biological research and can be performed by following the step-by-step procedure mentioned above. It is of interest to researchers, scientists, and professionals working in molecular biology, genetics, disease research, pharmaceuticals, biotechnology, plant biology, and forensic science.
