7 protocols using genomic dna analysis screentape

1

Bonamia Specificity Assessment via LAMP

Check if the same lab product or an alternative is used in the 5 most similar protocols
Specificity of the LAMP assays was evaluated by testing samples infected with B. ostreae or B. exitiosa originating from different geographic sites for assessing test inclusivity (to make sure the assay would not miss some targeted parasites) and with closely related parasites for assessing exclusivity (to make sure the assay would not amplify parasites other than parasites of the genus Bonamia). Additionally, a selection of LAMP products was examined with TapeStation Analysis Software A.02.02 using the Genomic DNA screen tape analysis (Agilent Technologies) to visualize the appearance of primer dimmers or other artefacts.

Exome Sequencing of Family Members

Blood samples were initially collected from the participants and DNA was prepared as previously described (Svensson et al. 2011 (link)). We re-measured available DNA concentration of available genomic DNA from family members using Qubit BR dsDNA assay (Life Technologies, USA). Individuals III:2, IV:1, IV:5, IV:6, IV:7, IV:9, IV:11, V:6, V7 and V:8 were selected for exome sequencing (Fig. 1a). All DNA samples used for exome sequencing were tested for DNA degradation using Genomic DNA ScreenTape analysis (Agilent Technologies, USA). Subsequently, 100 ng non-degraded genomic DNA per sample was used in AmpliSeq library preparations followed by Ion Proton (Life Technologies, USA) sequencing at the Science for Life Laboratory, Uppsala, Sweden, according to standard protocols. AmpliSeq target regions are available upon request. The Ion Proton sequencing was performed on P1 chips producing 200-bp sequence reads.

Library preparation and sequencing were performed by Admera Health (South Plainfield, NJ, USA). Isolated genomic DNA was quantified with Qubit 2.0 DNA HS Assay (ThermoFisher, Waltham, MA, USA) and DNA quality was evaluated by Genomic DNA ScreenTape analysis (Agilent Technologies, Santa Clara, CA, USA). Library preparation was performed using Nextera XT library kit (Illumina, San Diego, CA, USA) following the manufacturer’s recommendations while barcoding was performed using Illumina 8-nt dual-indices. The final library was evaluated by Qubit 2.0 DNA HS Assay and the quality of the library generated was examined by TapeStation HSD1000 ScreenTape (Agilent Technologies). Final library quantity was measured by KAPA SYBR FAST qPCR with QuantStudio 5 System (Applied Biosystems, Waltham, MA, USA). Equimolar pooling of libraries was performed based on qPCR QC values before sequencing on an Illumina HiSeq with a read length configuration of 2 × 150 paired end reads, obtaining 1 M PE reads per sample.

Tumor sample preparation and nucleic acid extraction

Snap frozen samples were sectioned and embedded in OCT. Frozen section slides were cut on a cryostat with a section depth of 5um, stained with hematoxylin and eosin. Diagnosis was confirmed and all samples were reevaluated for cellular content and quality by a pathologist (F.K.H. or S.J.C). After visual inspection, samples with > 70% tumor were macrodissected from the OCT block at a depth of up to 5mm for library preparation. Samples were disrupted with a mortar and pestle under liquid nitrogen and homogenized with a QIAshredder (QIAgen, 79654). DNA and RNA were extracted using the AllPrep kit (QIAgen, 80204). Germline DNA (peripheral blood) was extracted using DNeasy Blood and Tissue kit (Qiagen, 69504) according to manufacturer’s instructions. DNA was quantified using the Nanodrop 2000c (Thermo Fisher) and the QuBit High Sensitivity dsDNA assay (Thermo Fisher, Q32851). DNA integrity was quantified using the Genomic DNA Analysis ScreenTape (Agilent, 5067–5365) on the TapeStation 4200 (Agilent). RNA was quantified using Nanodrop 200c (Thermo Fisher) and QuBit High Sensitivity RNA assay (Thermo Fisher, Q32852). RNA was quantified using High Sensitivity RNA ScreenTape (Agilent, 5067–5579) on a TapeStation 4200 (Agilent).

Total genomic DNA was extracted from colon digesta of n = 6 piglets/group using the QIAamp Fast DNA Stool Mini Kit (Qiagen, Hilden, Germany). After DNA quality control using the Genomic DNA Analysis ScreenTape on a 2200 TapeStation Instrument (Agilent Technologies) and concentration measurement using the Qubit dsDNA BR Assay Kit (Thermo Fisher Scientific), shotgun metagenomic libraries were generated using the Nextera DNA Library Preparation Kit (Illumina) according to the manufacturer’s instructions. Libraries were quality-controlled using the D5000 DNA Analysis ScreenTape on a 2200 TapeStation Instrument (Agilent Technologies), and sequenced on an Illumina NextSeq500 with 2 × 150 bp. Finally, sequencing reads were demultiplexed based on the used Nextera indices (dual indexing principle).

Illumina Sequencing of Sheared Genomic DNA

Check if the same lab product or an alternative is used in the 5 most similar protocols
Genomic DNA (10 ng) was sheared in an M220 Focused-ultrasonicator™ (Covaris Inc., Woburn, MA) using settings for an average fragment of 300, 500, or 700 base pairs. Genomic libraries were constructed for Illumina sequencing using Ovation® Ultralow Library Systems V2 (NuGEN Technologies Inc., San Carlos, CA) [22 (link)]. Libraries were barcoded to facilitate pooling during subsequent sequencing runs. Size distribution and concentration of genomic DNA libraries were analyzed by electrophoresis using Genomic DNA Analysis ScreenTape and D1000 ScreenTape on a 2200 TapeStation (Agilent). Barcoded genomic DNA libraries were pair-end sequenced using Illumina MiSeq Reagent v3 (600 cycles, 2 × 300 bp) kits (Illumina Inc., San Diego, CA).

Target capture was performed according to the manufacturer’s protocol using the SureSelect XT automation reagent kit (Agilent, Santa Clara, CA), and a paired-end sequencing library was prepared using a barcode. The size and quality of the genomic DNA were validated using the Genomic DNA Analysis ScreenTape and Genomic DNA Reagent together with the Agilent 4200 Tape station (Agilent). Libraries were sequenced using the TG NextSeq 500/550 High Output Kit v2 (Illumina, Inc., San Diego, CA) and TG NextSeq 500/550 Mid Output Kit v2 (Illumina, Inc.).

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.
