The total RNA of lung tissues was extracted using a FastPure® Cell/Tissue Total RNA Isolation Kit (Vazyme Biotech Co., Ltd., Nanjing, China) following the manufacturer’s instructions. First-strand cDNA was synthesized using HiScript® III SuperMix for qPCR (Vazyme Biotech Co., Ltd., Nanjing, China), and stored at −20 °C. A real-time PCR reaction system was prepared using the iTaq Master SYBR Green Super Mix (Bio-Rad Laboratories Inc., Hercules, CA, USA) and carried out with a CFX96 Thermal Cycler (Bio-Rad Laboratories Inc.). The expressions of genes were calculated using the 2−ΔΔCT method, and normalized to that of GAPDH. Table 1 shows the primer sequences.

Total RNA was extracted from lung tissues using the FastPure® Cell/Tissue Total RNA Isolation Kit (Vazyme Biotech Co., Ltd., Nanjing, China). First-strand cDNA was synthesized from total RNA using HiScript® III SuperMix for qPCR (Vazyme Biotech Co., Ltd., Nanjing, China). Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) analysis was performed using iTaq Master SYBR Green Super Mix (Bio-Rad Laboratories Inc., Hercules, CA, United States) and a CFX96 Thermal Cycler (Bio-Rad Laboratories Inc.). The relative expression of genes was normalized to that of GAPDH and calculated using the 2−ΔΔCT method (Livak and Schmittgen, 2001 (link)). Table 1 shows the primer sequences.

RNA samples were isolated from fresh bacterial cultures (OD600 = 1.0) using the SV total RNA isolation system kit (Promega). The integrity of RNA was visualized by agarose gel electrophoresis and the concentration of RNA was measured using a NanoDrop ND-100 spectrophotometer.
Reverse transcription PCR was performed using a HiScript III SuperMix for qPCR (Vazyme) according to the manufacturer’s instructions. Specific RT-qPCR primers listed in Table S1 were used to amplify central coding fragments of approximately 200 bp in length from different genes. The quality of primers for amplification capability was determined by the melting curve analysis. SYBR Green qPCR Master Mixes (Vazyme) was used according to the manufacturer’s instructions. As a control, RT-qPCR was similarly performed to analyze arcA gene expression. The absolute value of −ΔΔCt = −(ΔCt1 − ΔCt2) was calculated as described in the formula 2−ΔΔCt (Livak and Schmittgen, 2001 (link)). The RT-qPCR experiment was repeated at least twice and the cDNA samples were prepared from triplicate cultures each time.

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.
