Tri rna isolation reagent

Manufactured by Merck Group

The TRI RNA isolation reagent is a product designed for the extraction and purification of total RNA from a variety of sample types. It is a single-step RNA isolation method that utilizes guanidinium thiocyanate and phenol to effectively lyse cells and denature nucleoprotein complexes, allowing for the separation of RNA from DNA and proteins.

Quantitative Gene Expression Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total RNA was isolated from three cotyledons with the TRI RNA Isolation Reagent (Sigma-Aldrich) and treated with TURBO DNase (Ambion). Reverse-transcription and RT-qPCR analyses were performed as described in Garcia-Alcazar et al. (2017) (link). RT-qPCR amplifications were performed on a 7300 Real-Time PCR System (Applied Biosystems) and each quantitation consisted of three biological replicates, each with three technical replicates (except for the RNAi lines, which consisted of a single biological replicate). The UBIQUITINE3 housekeeping gene was used as an internal control and the absence of genomic DNA contaminating the RNA sample analyzed by RT-PCR was tested as previously described (Gimenez et al., 2010 (link)). Statistical analyses were performed using Student’s t-tests.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
