The quantity and quality of the purified total RNA was assessed using a Thermo Fisher Scientific Qubit 3.0 fluorometer with the Qubit RNA BR Assay Kit (Cat # Q10211, Thermo Fisher Scientific) and an Advanced Analytical Fragment Analyzer System using a Fragment Analyzer RNA Kit (Cat # DNF-471, Agilent Technologies, Santa Clara, USA), respectively. Sequencing libraries were constructed using an Illumina TruSeq Stranded mRNA Library Prep kit (20020595, Illumina, San Diego, USA) in combination with TruSeq RNA UD Indexes (Cat # 20022371, Illumina) according to Illumina’s guidelines. The cDNA libraries were evaluated using a Thermo Fisher Scientific Qubit 3.0 fluorometer with the Qubit dsDNA HS Assay Kit (Cat # Q32854, Thermo Fisher Scientific) and an Agilent Fragment Analyzer (Agilent) with an HS NGS Fragment Kit (Cat # DNF-474, Agilent), respectively. Pooled cDNA libraries were sequenced 100 bp single-end on one lane of an Illumina HiSeq 3000 instrument (Illumina). All base call files were demultiplexed and converted into FASTQ files using Illumina bcl2fastq conversion software. The quality control assessments, generation of libraries, and sequencing were conducted by the Next Generation Sequencing Platform, University of Bern.

Total RNA was extracted with the RNeasy mini kit (Qiagen, Hilden, Germany) according to the manufacturer’s instructions. The quantity and quality of the isolated RNA was assessed using a Thermo Fisher Scientific Qubit 4.0 fluorometer with the Qubit RNA BR Assay Kit (Q10211, Thermo Fisher Scientific, Reinach, Switzerland) and an Advanced Analytical Fragment Analyzer System with a Fragment Analyzer RNA Kit (DNF-471, Agilent, Basel, Switzerland). The RNA was also tested by spectrophotometry using a Denovix DS-11 FX (M/F) spectrophotometer/fluorometer to assess the purity of the RNA (DeNovix, Wilmington, DE, USA). The median RIN for the four samples was 9.85 (IQR 0.13). The two highest quality samples (RIN ≥ 9.9), representing one asthmatic and one control horse, were equally pooled based on their RNA concentration.

Total RNA was extracted from 5 × 106 cells using RNeasy Plus Mini Kit (Qiagen, 74204) according to the manufacturer’s protocol, and gDNA was eliminated by treatment with the RNase-Free DNase Set (Qiagen, 79254). Quality of RNA was assessed using the 2100 Bioanalyzer RNA 6000 Nano kit (Agilent) or the Fragment Analyzer RNA kit (Agilent), all samples had RNA integrity number (RIN) > 8. Total RNA (500 ng) from each sample was depleted of rRNA using the NEBNext rRNA Depletion kit (NEB, E7405L). Strand-specific RNA libraries were prepared using the NEBNext Ultra Directional RNA Library Prep kit (NEB, E7765s), assessed on the Bioanalyzer High Sensitivity DNA kit (Agilent) or the Fragment Analyzer HS NGS kit to ensure good quality and sequenced paired-end on a NextSeq500 (76 bp) or NextSeq 2000 (100 bp; Illumina) in 2–6 biological replicates. All samples are detailed in Supplementary Table 1. RNA-seq data processing and analysis are detailed in the Supplementary Methods.

For RNA extraction and library preparation, the tissue between the two inner central screws containing the remaining implant material and newly formed bone tissue was dissected, placed in RNALater® (Sigma-Aldrich), and stored at −20 °C. For total RNA extraction, samples were transferred into microtubes containing 1 ml TRIzol™ Reagent (Invitrogen™) and metal beads for tissue disruption in a benchtop tissue homogenizer (TissueLyser 2, Qiagen, Hilden, DE).
RNA was isolated according to the manufacturer's instructions using the NucleoSpin® RNA Plus Kit (Macherey-Nagel, Oensingen, CH), and genomic DNA was removed by digestion with the provided DNase. The quantity and quality of the purified total RNA was assessed using a Thermo Fisher Scientific Qubit 4.0 fluorometer with the Qubit RNA BR Assay Kit (Q10211, Thermo Fisher Scientific, Waltham, Massachusetts, USA) and an Advanced Analytical Fragment Analyzer System using a Fragment Analyzer RNA Kit (DNF-471, Agilent Technologies, Santa Clara, California, USA), respectively.

PacBio Iso-Seq for Transcriptome Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
The quantity and quality of the extracted RNA was assessed using a Thermo Fisher Scientific fluorometer (Qubit 4.0) with the Qubit RNA BR Assay Kit (Thermo Fisher Scientific, Q10211) and an Advanced Analytical Fragment
Analyzer System using a Fragment Analyzer RNA Kit (Agilent, DNF-471),
respectively. The RNA was also tested by spectrophotometry using a Denovix DS-11 FX Spectrophotometer / Fluorometer to assess the purity of the RNA. Once all quality control tests confirmed high quality RNA, the "Procedure & Checklist -Iso-Seq Express Template Preparation for Sequel and Sequel II Systems" was followed (PN 101-763-800 Version 02 (October 2019)). Two libraries were created from the same total RNA input (300 ng):
one targeting 2KB transcripts and one targeting >3Kb transcripts. Both libraries were SMRT sequenced using a Sequel binding plate 3.0, sequel sequencing plate 3.0 with a 20h movie time on a PacBio Sequel system on their own SMRT cell 1M v3 LR. The 2Kb library was loaded at 3pM and generated 33.90 Gb and 409'187 ≥ Q20 Circular consensus reads (CCS).
While the >3Kb library was loaded at 3pM and produced 27.04 Gb and 248'304 ≥Q20 CCS. All steps post RNA extraction were performed at the Next Generation Sequencing Platform, University of Bern.

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.
