Total RNA was extracted with TRIzol (Life Technologies, Foster City, CA, USA), according to the manufacturer's instructions. RNA quantification was performed by Qubit Fluorometer (Life Technologies). Contaminant DNA was removed using deoxyribonuclease 1 (DNase I Amplification Grade; Life Technologies). DNase-treated RNA was reverse transcribed by using a High Capacity RNA-to-cDNA Kit (Life Technologies), according to the manufacturer's instructions. Resulting cDNAs (30 ng per sample) were amplified through an ABI PRISM 7900HT Fast Real-Time PCR System (Life Technologies), as previously described (26 (link)). Single-gene specific assays were performed through real-time PCR by using Fast SYBR Green Master Mix (Life Technologies) according to the manufacturer's instruction. To allow statistical analysis, PCRs were performed in three independent biological replicates. The list of the primer pairs used for comparison analysis is reported below.

DNA contamination was removed using deoxyribonuclease 1 (DNase I Amplification Grade; Life Technologies). DNase-treated RNA was reverse transcribed by using High Capacity RNA-to-cDNA Kit (Life Technologies) according to manufacturer's instructions. Resulting cDNAs (200 ng per sample-loading port) were loaded into custom TLDAs, format 96a (Life Technologies), and amplified through a standard thermal cycling profile on an ABI PRISM 7900HT Fast Real-Time PCR System (Life Technologies). Single-gene specific assays were performed through real-time PCR by using Fast SYBR Green Master Mix (Life Technologies) according to manufacturer's instruction. To allow statistical analysis, PCRs were performed in three independent biological replicates. Primer sequences are available upon request.

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.
