Cells were sorted as described in “Tissue Preparation and Flow Cytometry” and immediately lysed with RLT Buffer from the Qiagen RNeasy Plus Mini kit or RNA extraction buffer from PicoPure RNA isolation kit (Arcturus Bioscience, Inc.). Cell lysates were stored at −80°C until RNA was extracted. RNA isolations were performed using the Qiagen RNeasy Plus Mini kit or PicoPure RNA isolation kit. RNA quality and quantity were measured using the Agilent Technologies High Sensitivity RNA ScreenTape System. SMART-Seq v4 Ultra Low Input RNA kit (Clontech Laboratories, Inc.) was used for full-length cDNA synthesis, and the Nextera XT DNA sample preparation kit (Illumina Inc.) was used for library preparation. DNA libraries were sequenced on an Illumina NextSeq 500 instrument with a target read depth of ∼10 million aligned reads per sample. The pool was denatured and diluted, resulting in a 2.5 pM DNA solution. PhiX control was spiked at 1%, and the pool was sequenced by 1 × 75 cycles using the NextSeq 500 High Output reagent kit (Illumina Inc.).

Optimized Library Preparation for Illumina Sequencing

Check if the same lab product or an alternative is used in the 5 most similar protocols
A quality analysis (Bioanalyzer, Agilent, Santa Clara, CA, USA) was
performed to check DNA amplicon length prior to library preparation. A total of
255 libraries (242 samples, 9 PCR negative controls with Sigma water and 4 PCR
negative controls containing human DNA) were prepared using the TruSeq Nano DNA
Sample Preparation kit according to the user guide revision A (Illumina, San
Diego, CA, USA) with the following modifications: as each sample consisted of
approximately 200–400 bp long PCR products, the tagmentation, end-repair and size
selection steps were omitted, and hence the library preparation started with
adenylation of 3’-ends. We used 75 ng of PCR product as input in a volume of
17.5 μl of resuspension buffer and 2 adaptor indexed primers were ligated to each
sample.
All individual libraries were validated, normalised to 2 nM and
pooled in different pools. Each pool contained approximately 48 libraries
(including specimens and negative controls) and was denatured and diluted,
resulting in a 1.8 pM DNA solution. All library pools were sequenced paired-end
151 + 151 cycles once, using the NextSeq 500 instrument and NextSeq 500 High
Output reagent kit (Illumina) as described in the user guides Denature and Dilute
Libraries Guide v02 for the NextSeq System, NextSeq 500 kit Reference Guide
revision F and NextSeq 500 System Guide v02.

Illumina NextSeq library preparation

Check if the same lab product or an alternative is used in the 5 most similar protocols
Libraries were prepared for all 201 samples (188 samples and 13 negative controls), using the TruSeq Nano DNA Sample Preparation kit according to the user guide revision A (Illumina). As PCR products ranged in size from 181 bp to 375 bp, no tagmentation was necessary and library preparation started with adenylation of 3’-ends. 4.4 ng/μl (75 ng in a total volume of 17,5 μl) of PCR product were used as input material and 2 adaptor indexed primers were ligated to each sample. Individual libraries were validated, normalized and pooled, resulting in a 1.8 pM denatured DNA solution. Pools containing approximately 47 libraries were sequenced paired-end 151+151 cycles once, using the NextSeq500 instrument and NextSeq 500 High Output reagent kit (Illumina) as described in the user guides Denature and Dilute Libraries Guide v02 for the NextSeq System, NextSeq 500 kit Reference Guide revision F and NextSeq 500 System Guide v02.

RNA-seq Analysis of Epithelial Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Epithelial cells were immediately lysed using RLT buffer from the Qiagen RNeasy Plus Mini kit (Qiagen). Cell lysates were stored at -80°C until RNA was extracted. RNA isolations were performed using Qiagen RNeasy Plus Mini kit (Qiagen). RNA quality and quantity were measured using Agilent 4200 Tapestation using high Sensitivity RNA ScreenTape System (Agilent Technologies). NEBNext Ultra™ RNA (New England Biolabs, Inc) was used for full-length cDNA synthesis and library preparation. Libraries were pooled, denatured and diluted, resulting in a 2.5 pM DNA solution. PhiX control was spiked at 1%. Libraries were sequenced on an Illumina NextSeq 500 instrument (Illumina Inc), using NextSeq 500 High Output reagent kit (Illumina Inc) (1×75 cycles) with a target read depth of approximate (5-10) million aligned reads per sample. “edgeR” package (R, Bioconductor) was used to analyze sequencing data. Briefly, reads were assessed for quality, aligned to hg19 human reference genome using TopHat algorithm, and normalized and annotated count data were analyzed for differential expression using “deseq2” protocol. All resulting RNA-seq data will be made publically available in NCBI's GEO Omnibus repository.

Nextera DNA Library Preparation

50 ng of genomic DNA per sample was tagmented with 2 unique indices, as described (Nextera DNA Sample Preparation kit, user guide revision B (Illumina)). The individual libraries were validated, normalized to 4 nM, pooled, denatured and diluted, resulting in a 2.6 pM DNA solution, which was spiked at 1% PhiX control and the library pool was sequenced paired-end 151+151 cycles using NextSeq 500 High Output reagent kit (Illumina) as described in the user guides “Denaturing and Diluting Libraries for the NextSeq 500” revision A and “NextSeq 500 kit Reference Guide” revision F.

RNA from cell lines was isolated using the RNAeasy Plus mini kit (Qiagen, Germany). RNA quality and quantity were measured using Agilent 4,200 Tapestation with the high Sensitivity RNA ScreenTape System (Agilent Technologies). Briefly, mRNA was isolated from 80 ng of purified total RNA using oligo-dT beads (New England Biolabs, Inc). An NEBNext Ultra™ RNA kit (New England Biolabs, United States) was used for full-length cDNA synthesis and library preparation. Libraries were pooled, denatured and diluted, resulting in a 2.0 p.m. DNA solution. PhiX control was spiked at 1%. Libraries were sequenced on an Illumina NextSeq 500 instrument (Illumina Inc) using NextSeq 500 High Output reagent kit (Illumina Inc) (1x75 cycles) with a target read depth of approximate (5–10) million aligned reads per sample.

Nextera-based DNA library preparation

50 ng of WGA genomic DNA per sample (n = 95) was used for DNA library preparation with a dual index system using the Nextera DNA Sample Preparation kit according to the user guide revision B (Illumina). The individual libraries were validated and normalized to 4 nM. Libraries were then divided in 4 sets, each set containing at least 3 negative controls (1 water control and 2 blank blocks) and 20 NMSC specimens. Each set was denatured and diluted, resulting in a 1.8 pM DNA solution, and finally sequenced by paired-end 151+151 cycles using NextSeq 500 High Output reagent kit (Illumina).

Check if the same lab product or an alternative is used in the 5 most similar protocols
Libraries were sequenced on an Illumina NextSeq 500 instrument (Illumina Inc) using NextSeq 500 High Output reagent kit (Illumina Inc) (1 × 75 cycles) with a target read depth of approximately (5–10) million aligned reads per sample. FASTQ files were generated using bcl2fastq 2.19.1 (Illumina). To facilitate reproducible analysis, samples were processed using the publicly available nf-core/RNA-seq pipeline version 3.4 implemented using nextflow 21.10.5.5658 and singularity 3.8.12 with the public nu_genomics configuration. The STAR/Salmon method was used for transcriptome alignment and gene-level count assignment. The GRCm38 genome (Ensembl release 81) was used as a reference. The resulting length-scaled DESeq2 object was then imported directly for downstream analysis.

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.
