Total RNA was obtained from cerebral arteries of control and TBI animals using a Trizol isolation procedure and reverse transcribed into cDNA with the High Capacity cDNA Kit (Applied Biosystems). Quantitative polymerase chain reaction (qPCR) was performed using an ABI PRISM 7900HT Sequence Detection System (Applied Biosystems); iNOS‐, eNOS‐, nNOS‐, and GAPDH‐specific primers; and PerfecCta qPCR supermix (Quanta Biosciences), as reported previously.42 (link) Briefly, a total of 6.6 ng of DNAse I‐treated RNA was reverse transcribed into cDNA using the High Capacity cDNA Kit (Applied Biosystems) in a 20 μL reaction. Moreover, qPCR was performed in duplicate for each sample using 1 μL of cDNA as a template for all NOS targets, 1× PerfeCta qPCR supermix (Quanta Biosciences), and 1× Taqman gene expression assays in a 20 μL reaction. qPCR was carried out in an ABI PRISM 7900HT Sequence Detection System (Applied Biosystems) using the following conditions: 45°C for 5 minutes and 95°C for 3 minutes followed by 40 cycles of 15 seconds at 95°C and 45 seconds at 60°C. We amplified GAPDH as a normalizing internal control. To calculate the relative index of gene expression, we used the 2−ΔΔCt method43 (link) using control samples for calibration.

Quality of the extracted RNA was assessed by 1% agarose gel electrophoresis and from the A260nm/A280nm absorbance ratio (Nanodrop 1000, ThermoFisher Scientific). Next, cDNA was synthesized using the High Capacity cDNA Kit (ThermoFisher Scientific) with either random (provided by manufacturer) or specific primers (see Primers and probes section below). Finally, processed and unprocessed RNA expression levels were assessed using the ΔΔCq method57 (link). The primer/probe sets were designed, and their compatibility validated in silico. A serial dilution approach was used to validate the multiplex reaction. All qPCR reactions were carried out on either a StepOnePlus or QuantStudio 5 thermal cycler (ThermoFisher Scientific).

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.
