RNA Isolation and qRT-PCR Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total RNA was isolated from heads with TRIzol (Invitrogen) and treated with Turbo DNase (Invitrogen) to degrade contaminating DNA. For qRT-PCR analyses, cDNA was generated using MMLV Reverse transcriptase (Invitrogen) from 1 μg of total RNA, and then used as template for quantitative real-time PCR (qPCR) from duplicate samples of 10 ng cDNA with QuantiTect SYBR Green Master Mix using an Applied Biosystems StepOne Plus real time machine (ABI). Results were analyzed using the ΔΔCT method and normalized to Act5c as fold change relative to control. Oligonucleotide sequences are provided in (S1 Table).

Quantitative Real-Time PCR Analysis of mRNA

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total RNA was isolated from N2a cells using the TRIzol reagent (Invitrogen) according to the manufacturer's protocol. Isolated RNA was treated with Turbo DNase (Invitrogen) to degrade contaminating DNA. For qRT-PCR analyses, cDNA was generated using the MMLV Reverse transcriptase (Invitrogen) from 1 μg of total RNA. Relative mRNA levels were measured by quantitative PCR analysis of duplicate samples of 15 ng cDNA with QuantiTect SYBR Green Master Mix using an Applied Biosystems StepOne Plus real time machine (ABI). Results were analyzed using the ΔΔCT method and normalized to 18S rRNA. Oligonucleotide sequences are provided in Supplementary Table S2.

Quantitative RT-PCR Methodology

Check if the same lab product or an alternative is used in the 5 most similar protocols
For qRT-PCR analyses, 1 μg of total RNA was transcribed to cDNA as described above. Relative mRNA levels were measured by quantitative PCR analysis of triplicate samples of 10 ng of cDNA with QuantiTect SYBR Green Master Mix using an Applied Biosystems real time machine (ABI). Fold change was calculated using the ΔΔCt method, by normalizing to the HPRT transcript for the first ΔCt and to either control IgG IP samples (siRNA mediated knockdown followed by endogenous protein RNA-immunoprecipitation) or primers sets for the coding sequence (siRNA mediated knockdown affect on polyadenylation site usage and retained intron) for the second ΔCt. Statistical significance was determined using Student's t-test. A list of primers used for these analyses is shown in Supplemental Table S1.

RNA Extraction and Quantitative PCR Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total RNA was isolated from adult tissues with TRIzol (Invitrogen) and treated with DNase I (QIAGEN). For RT-PCR, cDNA was generated using SuperScript III First Strand cDNA Synthesis (Invitrogen) from 2 μg of total RNA, and PCR products were resolved and imaged on 2% agarose gels (Bio-Rad image). Quantitative real-time PCR (qPCR) reactions were carried out in biological triplicate with QuantiTect SYBR Green Master Mix using an Applied Biosystems StepOne Plus real-time machine (ABI). Results were analyzed using the ΔΔCT method, normalized as indicated (e.g., to Act5C), and plotted as fold-change relative to control.

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.
