Rna stat reagent

Manufactured by Tel-Test
Sourced in United States

RNA STAT reagent is a chemical solution used in molecular biology laboratories to extract and isolate ribonucleic acid (RNA) from various biological samples. The reagent facilitates the lysis of cells and the subsequent purification of RNA, which is essential for various downstream applications such as gene expression analysis, reverse transcription, and RNA sequencing.

5 protocols using rna stat reagent

1

Quantitative Real-Time PCR Analysis of Proinflammatory Mediators

The mRNA expression of proinflammatory mediators was analyzed by quantitative
real-time PCR.23 (link)
After appropriate stimulation, total RNA was isolated from HMO6 cells
using RNA STAT reagent (Tel-Test, Friendswood, Tx, USA) according to the
manufacturer’s instructions. Two μg of total RNA was reverse transcribed using
reverse transcriptase enzyme (ReverTraAce, Toyobo, Osaka, Japan), and
quantitative real-time PCR was done with SyBr green real-time PCR system
(Applied Biosystem, Warrington WA1 4SR, UK) and gene-specific primers, using an
ABI Prism 7300 Sequence Detection System (Applied Biosystem).

Transcriptional Profiling of atfs-1 Mutant C. elegans

Check if the same lab product or an alternative is used in the 5 most similar protocols
Wildtype (N2) and atfs-1(et18) worms were synchronized by bleaching, and harvested at the L4 stage of development. Total RNA was extracted using the RNA STAT reagent (Tel-Test Inc.) and used for double-stranded cDNA synthesis using the iScript cDNA Synthesis Kit (Bio-Rad Laboratories). Microarray analysis using GeneChip C. elegans genome arrays (Affymetrix) was conducted as previously described4 (link). Differences in gene expression between wildtype and atfs-1(et18) worms was determined using Anova streamlined (Partek Genomic Suite (v6.5)). Supplementary Table 1 contains the relative fold induction and p values for each mRNA. Confirmation of the microarray results was performed via qRT-PCR as described4 (link). Primers are listed in Supplementary Table 2.

Quantifying Gene Expression by qPCR

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total RNA was isolated using the RNA STAT reagent (Tel-Test) and treated with DNAse (Ambion). cDNA was then synthesized from total RNA using the iScript™ cDNA Synthesis Kit (Bio-Rad Laboratories). qPCR was used to determine the expression levels of the indicated genes using iQ™ sybr green supermix and MyiQ™2 Two-Color Real-Time PCR Detection System (Bio-Rad). Gene specific primers are listed in Table S6. Actin was used as a control. Fold changes in gene expression were calculated using the comparative CtΔΔCt method.

Quantification of Gene Expression from Frozen Liver

Check if the same lab product or an alternative is used in the 5 most similar protocols
Frozen liver tissue, 5 to 20 mg, was homogenized in 1 ml RNA-STAT reagent (Tel-Test) with isopropanol and EtOH precipitation. RNA pellets were resuspended in 200 μl water and assessed by Nanodrop (ThermoFisher Scientific). RNA, 1 μg, was reverse transcribed into cDNA by Superscript VILO kit (ThermoFisher Scientific), using an Applied Biosystems 2720 Thermal Cycler (ThermoFisher Scientific). qPCR was performed for all samples in duplicate with Power SYBR Green using an Applied Biosystems QuantStudio-3 real-time thermocycler (ThermoFisher Scientific). Target gene Ct values were normalized to reference gene (Rplp0) Ct values by the 2−ΔΔCt method. Oligonucleotide primer sequences are listed in electronic supplementary material Table S1.

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.
