Whole heads were dissected from five adult male flies, and RNA was extracted using Trizol, followed by Zymoprep Direct-zol RNA MicroPrep kit (Zymo Research, Zurich, Switzerland, Cat # R2050) with DNAase I treatment. cDNA was generated from 100 ng of RNA using Episcript Reverse Transcriptase (Epicentre, Petaluma, CA, USA) and random hexamer primers. RT-qPCR was conducted as previously described [44 (link)]. Catalase gene expression was normalized to the geometric mean of two reference genes (RpL32, eIF1a). Statistical significance was determined using Student’s t-test.

Total RNA samples were extracted from peritoneal neutrophils and prostate Gr (+)- and Gr (–)-sorted cells using TRIzol (Thermo Fisher, Carlsbad, CA). RNA was subsequently purified using Direct-zol RNA miniprep kit (Zymo Res., Irvine, CA) according to manufacturer's instructions. Then, 0.5 μg of RNA was used as a template for reverse transcription using EpiScript™ Reverse Transcriptase (Epicentre, Madison, WI) with random hexamer primers (Fermentas, Thermo Fisher, Carlsbad, CA). qPCR was performed with power SYBR green PCR master mix (Applied Biosystems, Foster City, CA) in a ABI Prism 7500 detection system (Thermo Fisher, Carlsbad, CA). The expression of ACTB was chosen as housekeeping gene. Data analysis was based on the 2−ΔΔCt method for normalization of raw data. All primers used are described in the Supplementary Table 1.

Total RNA was isolated using TRIzol® reagent (Invitrogen, Carlsbad, CA, USA). cDNA was made using EpiScript reverse transcriptase (Epicentre, WI, USA). Expression levels were measured by real-time PCR using SYBR and CFX real-time PCR detection system (Bio-Rad, Hercules, CA, USA). The PCR protocol was: 95 °C, 10 min, followed by 95 °C, 15 s and 60 °C, 30 s for 40 cycles. Rpl35a served as an internal control. Table 1 shows primer sequences.

Quantitative RT-PCR for Drosophila Gene Expression

Check if the same lab product or an alternative is used in the 5 most similar protocols
RNA was isolated using the Zymoprep Direct-zol RNA MicroPrep kit (Zymo Research) and treated with DNAse I as per the kit protocol. cDNA was generated from 250 ng of RNA using Episcript Reverse Transcriptase (Epicentre) using either oligo dTs or random hexamer primers as indicated. qPCR was conducted using Evagreen 2X Mix (Biotium) and the CFX Connect Real-time system (Biorad). Quantities were determined relative to a 4-fold dilution series of wild-type (OregonR) cDNA. Primers against SAGA-regulated genes were taken from previous studies [40 (link)]. New primers used in this study are as follows: SF3B5 5′-GCAAAATGGGTGAACGCTAC-3′ and 5′-AGCCACTCGAACTTTGTGGT-3′, Sas10 5′-ACCGGTGCTCAACTACGTTC-3′ and 5′-GCTCCTCGATCAGATCCTTG-3′, Oda (unspliced) 5’-CCGTGCAAAAAGTGAATGTG-3’ and 5’-GCCAACCTGGAGAACGTCTA -3’, Sap47 (unspliced) 5’-ATCGATATTCCGCTTGTTGC-3’ and 5’-GCGCAAGTTTGATATTGTCG-3’, exba (unspliced) 5’-GAGCCCAAGGACAGGATTG-3’ and 5’-TGCTTGAACGTCTGGAACAG-3’, Crc (unspliced) 5’-′CGGACGAGTTGTCAACAGAA-3’ and 5’-′TCTGAAGATGCACCGAATTG-3’.

Total RNA Extraction and RT-PCR Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total RNA was extracted with TRIzol reagent (Invitrogen, Carlsbad, CA) according to the manufacturer's instructions. Thereafter, 1 μg of total RNA was used as a template for reverse transcription using EpiScript™ Reverse Transcriptase (Epicentre, Madison, WI) with random hexamer primers (Thermo Fisher Scientific, Waltham, MA USA). The cDNA obtained was subjected to PCR amplification using GoTaq DNA Polymerase (Promega, Madison, WI), and following this, PCR protocols were performed according to the manufacturer's instructions. PCR amplification was performed in 10 μl using a specific primers sets (Table 1), and the PCR amplified products were visualized by electrophoresis onto 2% agarose gels by GelSampleRed TM (Biotium) staining, whit the band densitometric analysis being carried out using ImageJ software.

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.
