Briefly, the wild-type strain was grown to OD600 0.6–0.8 and then treated with 0.125 and 0.25 μg/ml STR for 2, 4, 6, 12, and 24 h. The broth was collected and the RNA was extracted, as described previously (Yang et al., 2012 (link)). The cDNA was obtained using the HiScript II Q RT kit (Vazyme, Nanjing, China). The qRT-PCR system consisted of 20 μl solution containing 10 μl 2 × SYBR Green qPCR mix, specific primers, and 1 μl of cDNA. The qRT-PCR was performed on Roche 480 instrument as follows: 95°C for 1 min and 40 cycles of 95°C 15 s, 60°C 15 s, and 72°C 30 s. The expression level of each gene was normalized with sigA as an internal reference. Gene relative expression was determined according to the 2–ΔΔCt method (Livak and Schmittgen, 2001 (link)).

Quantitative Real-Time PCR Gene Expression

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total RNA was extracted from cell by using Trizol reagent (Sigma; T9424). The quantity and quality of RNA were determined using a ScanDrop2 nano-volume spectrophotometer (Analytik Jena), and reversely transcribed based on the HiScript II Q RT kit (Vazyme; R223) according to the manufacturer’s instructions. Amplification and real-time detection were performed on a qTOWER3 G real-time PCR system (Analytik Jena) by using ChamQ Universal SYBR qPCR Master Mix (Vazyme; Q711) in 20 μL reaction. The relative expression levels of each targeted gene were normalized by subtracting the corresponding mouse β-actin threshold cycle (CT) values by using the ΔΔCT comparative method. Three biological replicates per group were used for qPCR. Primers were synthesized by Sangon Biotech (Shanghai, China). Sequences of all primers used are provided in Additional file 1: Table S3.

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.
