Using RNAssist : to Protect RNA in 2022

Written by Emma Rhys

In this article, rnassist is a molecular fixative and stabiliser that is universal for IF and standard paraffin embedding, and can also be used to extract biomolecules for downstream molecular analysis. It has been used successfully to fix a wide range of sample types, including viruses, prions, bacteria, Trypanosomes, and the microbiome. Its unique ion exchange capabilities make it ideal for molecular imaging and sequencing of a wide variety of biological samples.

Stabilisation With RNAssist

In this study, RNA samples were treated with a choline chloride/Urea (1:2) stabilisation solution. The samples were then stored at room temperature or 37 deg C for eighteen hours. The samples were then recovered intact, RNA was extracted, and immunohistochemistry performed. RNAlater treatment was found to increase hardness and reduce utility of tissue. It was also associated with higher costs and a shorter turnaround time.

One application of this technique involves the stabilisation of RNA or DNA. While this method is widely applicable to any cell type, it is most useful for samples taken from the human body. The method has the advantage of preventing the degradation of RNA, DNA, and proteins. It has the added benefit of being applicable to a variety of cell types and samples, including bacteria, fungal, animal, and plant cells.

RNA & Guanidine

RNA later and guanidine were found to be equally effective in stabilising RNAssist in whole blood. However, guanidine was more effective in preserving RNAssist than choline chloride. This difference between the two approaches is significant. However, guanidine is the more effective alternative. However, it is important to note that both methods have their own set of advantages and disadvantages. Once you’ve decided on the best RNAlater or guanidine solution for your sample, you’ll have a lot to choose from.

Diagnostic Kit

In some cases, the RNA IC may be included in a diagnostic kit. Generally, these kits are stored at room temperature or 4 deg C. However, stabilisation can improve the performance of the kit and ensure its integrity during transport. Stabilisation is also beneficial for diagnostic kits. Once stabilised, RNAlater will help improve the quality and performance of your kit. Once stabilised, RNA ICs can be used in a wide range of diagnostic tests.


There are many types of DES mixtures available on the market. The most important thing to look for when selecting a DES solution is compatibility with RNA. It must be compatible with the RNA purification protocol. It must also be compatible with the silica spin column used in RNA purification. RNAeasy is an example of this type of DES. These are all effective products that help RNA purification.

RNA Handling Cancer Cells

The stability of RNA in tissue samples is important to the study of the effects of ribonucleases on the synthesis of RNA molecules. In addition to these biological functions, RNA stabilisation can help preserve viral RNA and retroviruses. The invention is particularly beneficial for the treatment of cancer cells, which produce RNA as a side effect. This is an effective solution for a number of biomedical research projects.

Stabilisation With Monarch DNA/RNA Protection Reagent

To ensure the integrity of RNAssist, the Monarch DNA/RNA Protection Reagent has been formulated to protect RNA from degradation in a variety of samples. This reagent is compatible with Monarch Total RNA Miniprep kits and makes handling and sample storage a breeze. With the Monarch DNA/RNA Protection Reagent, you can store your samples in a convenient manner and use them over again.

Stabilisation with Monarch DNA/RNA protection reagent is an essential part of the Monarch Total RNA Miniprep Kit and is a great way to preserve nucleic acids in different types of tissue. This reagent is supplied as a two-fold concentration, and does not need to be removed prior to RNA extraction. It can also be used to purify RNA from nucleated blood.

Usage: Samples

This reagent is compatible with many samples, including those with high RIN values. Saliva samples contain approximately one microgram of RNAssist per ml, and therefore should be stabilized as quickly as possible after collection. Ensure that the sample is placed on ice until DNA/RNA Protection Reagent is added. If ethanol is present in the sample, it should be added after mechanical lysis. The next step is to add Monarch DNA/RNA Protection Reagent.

Monarch DNA/RNA Protection

The monarch DNA/RNA protection reagent is the perfect solution for all kinds of research projects. The product is effective against various diseases. Its benefits are well known and its use has been recommended by several scientists. RNAssist active ingredient, Xi Bao, is a powerful antioxidant that has anti-inflammatory and anti-viral properties. Moreover, it prevents DNA from being oxidised and is effective against cancer and infection.

Nano 6000 RNA chip

For the isolation of total RNA, the Monarch Total RNA Miniprep kit (NEB #T2010) is an excellent choice. The kit’s reagents allow the isolation of total RNA from HeLa cells, and it is compatible with multiple downstream applications. Once the total RNA is isolated, it is then analyzed on a Nano 6000 RNA chip and compared to the S. cerevisiae RNA by plant Nano assay. The RIN values and O.D ratios confirm that the RNA is highly pure and the overall integrity of the RNA is high.

RNA lysis

After the sample has been harvested and washed, it should be stored until processing. It can be stored frozen for long-term storage, refrigerated for medium-term storage, or room temperature for short-term storage. If the sample needs to be transported, it can be stored at room temperature. Add equal volumes of Monarch RNA Lysis Buffer. To prepare samples for RNA lysis, follow the protocol outlined below.

Stabilisation With Rnassist

RNA stabilisation involves the inactivation of ribonucleases by DES treatment and the entry of dissolved DES into the cell structure. The stabilisation process may also involve modification of hydrogen bonds. However, the exact mechanism is not yet known. There are three major factors to consider when performing RNA stabilisation with DES. Among these factors are:

Enhanced RNA Stabilisation Study

The RNA IC is an RNA that is included in diagnostic kits. Generally, the components of the kit are stored at room temperature or 4deg C. RNA IC stabilisation improves the performance of the kit and preserves the integrity of the RNA during transport. It is also suitable for use in a variety of therapeutic applications involving synthetic RNAssist. RNA stabilisation can also help in preserving viral and retrovirus RNA.

The stability of RNAs is an important step in biochemical research. As RNA is a highly sensitive and fragile biomolecule, the integrity of rRNA is critical for the proper functioning of other biomolecules. Its stability in the tissue sample affects the activity of ribonucleases and their ability to hydrolyse other biomolecules. RNAssist is an effective reagent for RNA stabilisation.

Biological Samples And Stabilising DNA, RNA And Proteins

In the present invention, a method is described for fixing the morphology of biological samples and stabilising DNA, RNA and proteins. The method is applicable to plant, animal and bacterial samples, including E. coli, yeast, and potato.

Molecular biology research has improved dramatically with the advent of novel reagents. RNAssist’s virusPHIX-P9 ™ is a universal biological sample stabilisation (VTM) that can be used to fix nucleic acids in cell culture and in lateral flow tests. It is also compatible with lateral flow tests, thereby allowing a wide variety of diagnostic applications.

Molar Ratio

The choice of DES mixtures depends on the molar ratios of each component. The molar ratio of one component to the other may influence the stabilisation activity of the other. In addition to the molar ratios, the mixing components must have specific properties that are compatible with the RNAssist purification protocol. Some DES solutions may have more than one molar ratio, which is often not desirable.
