Transcriptome Analysis of Spodoptera litura Midgut

Check if the same lab product or an alternative is used in the 5 most similar protocols
A total of 180 fifth-instar larvae were divided into three groups (60 larvae in each group) and treated with 3% coumarin. The high quality of RNA from S. litura midgut in each group was used for cDNA library construction based on Illumina’s protocols, and cDNA libraries were constructed with the TruSeq RNA Sample Preparation Kit v2 (Illumina, San Diego, CA, USA). Then, the prepared libraries were evaluated on an Agilent BioAnalyzer 2100 system, followed by sequencing on an Illumina HiSeq platform at Novogene (Tianjin, China). The obtained raw reads in fastq format were further processed to remove contained N base and low quality of reads using in-house perl scripts. The Q30 (percentage of sequences with sequencing error rate lower than 0.1%), Q20 (percentage of sequences with sequencing error rate lower than 1%), and the GC content of the clean data were determined.

Total RNA from each sample was used to construct lncRNA and miRNA library using the TruSeq Small RNA Sample Preparation Kit (Illumina, San Diego, CA, USA) according to the manufacturer’s instruction.
For lncRNA libraries construction, the ribosomal RNA was removed by Epicentre Ribo-zero™ rRNA Removal Kit (Epicentre, USA), and rRNA free residue was cleaned up via ethanol precipitation. Sequencing libraries were then generated using the rRNA-depleted RNA by NEBNext® Ultra™ Directional RNA Library Prep Kit for Illumina (NEB, USA) following manufacturer’s recommendations. The library quality was assessed on the Agilent Bioanalyzer 2100 system and sequenced on an Illumina Hiseq 2500 platform.
For miRNA libraries construction, we used the NEB Next Multiplex Small RNA Library Prep Kit (NEB, USA) following the manufacturer’s protocol. In brief, the RNA 3′ adaptor was specifically ligated to miRNA with the excess adaptor removed by hybridization. The 5′ ends of miRNA were then ligated to the 5′ adaptor, followed by reverse transcription to convert the ligated small RNA into cDNA, which was then uniquely indexed by PCR to generate the sequencing library. The quantified libraries were clustered to a flow cell and sequenced using TruSeq SBS Kit on a HiSeq system (Illumina).

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.
