Long range PCR amplification of the BCR-ABL1 transcript was performed using the Clontech Advantage PCR kit as previously described.12 (link)
The cDNA amplicons underwent end-repair and adaptor ligation to generate SMRTbell™ libraries for PacBio sequencing. SMRTbell™ libraries were quantified using the Qubit assay and library size was confirmed using the Agilent DNA 12000 Kit. Each SMRTbell™ amplicon library was loaded on to 1 SMRT cell and sequenced on the PacBio RS II instrument using C4 chemistry and a 120-minute movie time. Circular consensus sequence (CCS) reads were generated for each sample. The CCS reads in FASTQ format were used as input for the automated analysis pipeline.

Plasmid cloning vectors with spike-in sequence inserts were transformed into ECOS Competent Escherichia coli JM109 (Nippon Gene, Toiya, Japan) following the manufacturer's instructions. Plasmid DNA was extracted from overnight liquid cultures using the QIAGEN Plasmid Midi Kit. Plasmid DNA was then linearized using the following single-cutting restriction enzymes, according to the manufacturer's instructions: BpmI (New England Biolabs) for spike-ins Ec5001, Ec5002, Ec5005, Ec5502 and Ga5501; BsaI-HF (New England Biolabs) for Ec5003, Ec5004, Ec6001, Bv5501, Ca5501 and Tb5501; and ScaI (TaKaRa Bio) for Ec5501. Linearized plasmid DNA was purified using the Agencourt AMPure XP system (Beckman Coulter) and size and integrity were verified by electrophoresis using the Bioanalyzer 2100 with a DNA 12000 Kit (Agilent). DNA concentrations were determined with a high-sensitivity Quant-iT dsDNA Assay Kit (Invitrogen) using a Qubit Fluorometer 3.0 (Life Technologies). Plasmid DNA was diluted to 10 ng/μl in Tris-EDTA (TE) buffer (pH 8.0) and distributed in single-use aliquots stored at −80°C. Spike-in sequences were verified by Sanger sequencing (see Supplementary Data for details) and experimentally determined sequences were in all cases in agreement with designed sequences. Spike-in standard mixes were prepared based on estimated copy numbers and stored in TE buffer at −20°C until use.

Total RNA was extracted from cells using the RNA Easy mini kit (Qiagen, Cat # 74104), and RNA integrity was evaluated using an Agilent Bioanalyzer 2000. Competitive RT-PCR was performed with a one-step RT-PCR kit (Qiagen, Cat # 210210) using the following primer sets containing an equimolar ratio of MCL-1 (forward, 5′-GGGCAGGATTGTGACTCTCATT- 3′; reverse, 5′-GATGCAGCTTTCTTGGTTTATGG-3′) against β-actin (forward, 5′-TCACCCACACTGTGCCCATCTACGA- 3′; reverse, 5′-CAGCGGAACCGCTCATTGCCAATGG-3′). Reverse transcription was coupled with PCR (25 cycles) on a thermocycler (Eppendorf, Mastercycler® GX2). PCR products were quantified on the Agilent Bioanalyzer 2000 using the DNA 12,000 kit (Cat # 5067-1508). In brief, samples were loaded onto DNA microchips, and the DNA fragments were then separated by capillary electrophoresis. The target DNA sizes and relative quantities were calculated on the basis of DNA ladders and an internal marker, respectively. The associated software then generates agarose gel-like images.

PacBio Sequencing of Amplified DNA

Check if the same lab product or an alternative is used in the 5 most similar protocols
The RCA product of the simple community was purified and concentrated with 1× volume AMPure® PB Beads (100-265-900, PacBio, Menlo Park, CA, USA) giving 7 μg of purified product, determined by Qubit 2.0 fluorometer (Life Technologies, Carlsbad, CA, USA). The purified product was gently sheared (to reduce hyperbranched DNA structures) using Covaris® g-TUBE™ device (Covaris, Woburn, MA, USA) at 6,000 rpm for 1.5 min. To verify the size of fragments after shearing, sheared and unsheared products were run on a 0.5 % (w/v) agarose gel. The sheared RCA product was purified with 0.45× AMPure® Beads and was used to prepare the 10 kb SMRTbell™ template in accordance with the Pacific Biosciences procedure for ‘10 kb Template Preparation and Sequencing’. BluePippin™ (Sage Science, Beverly, MA, USA) was used to select libraries of sizes ranging from 6-10 kb. The distribution of library sizes was first assessed on Agilent 2100 Bioanalyzer (Agilent Technologies, Inc., Santa Clara, CA, USA) with the DNA 12000 kit (5067-1509, Agilent Technologies, Inc.) before they were sequenced on a PacBio sequencer, using P5-C3 chemistry coupled with MagBead Standard Seq v2 collection protocol.

DNA was extracted from 10 g of sediment sample for each experiment replicate, using the MoBio PowerSoil DNA Isolation kit (MO BIO Laboratories, USA) according to the manufacturer’s protocol. DNA concentrations of the extract were measured with a Qubit fluorometer. For each library construction, about 100 ng DNA was fragmented with Covaris S2 (Covaris, USA) and was used to construct metagenomic DNA library with NEXTflex™ DNA Sequencing Kit compatible with the Biomek® FXp (Bio Scientific, USA). Notably, PCR amplification was limited to 12 cycles for each Illumina library. The quality of DNA library was examined by Agilent Bioanalyzer 2100 (Agilent, USA) with DNA 12000 Kit. Paired-end Illumina sequencing (2 × 150 bp) was performed for each metagenomic library on Hiseq Xten instruments (Illumina).

PacBio Sequencing of Schistocerca gregaria

Check if the same lab product or an alternative is used in the 5 most similar protocols
The library preparation for PacBio sequencing was performed with a "SMRTbell Template Prep Kit 1.0" according to the PacBio protocol (version 100-286-000). For each of the two libraries, 10 µg of the
S. gregaria high-molecular-weight DNA was used as input in two parallel 50-µl reactions.
For library size selection, a "0.75% Dye-Free Agarose Gel Cassette” (ref: BLF7510) was used on a Blue Pippin (Sage Science) with the "0.75% DF Marker S1 high-pass 15–20kb" protocol for a lower cut-off of 12 kb. Fragment size distribution was determined with a “DNA 12000 kit” (ref: 5067-1508) for the first library and a “Fragment Analyzer (Agilent) - High Sensitivity Large Fragment 50 kb kit” (ref: DNF-464-0500) for the second library. The resulting libraries had an average length of 16.5 and 22 kb, respectively.
No extension time was used for the sequencing as recommended for size selected libraries in the “Quick Reference Card 101-461-600 version 07”. The first run was performed on a PacBio RSII System (V4.0 chemistry, polymerase P6). Fifteen additional runs were performed on a PacBio Sequel system with 2.0 Chemistry, polymerase and SMRTCells. The same conditions were used to sequence 20 more SMRTCells with the second library on the PacBio Sequel system.

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.
