Libraries were amplified on an Applied Biosystems Veriti 96 well Thermal Cycler (Thermo Fisher Scientific) in a total reaction volume of 130 μl, containing 100 μl of Platinum®PCR SuperMix High Fidelity, 5 μl of Library Amplification Primer Mix (both provided by the IPFL kit) and 25 μl of unamplified library. The cycling program suggested on the IPFL kit protocol was applied. Amplified libraries were purified with Agencourt® AMPure® XP Kit for DNA purification (Beckman Coulter, Beverly, Massachusetts, USA) on a DynaMag-2 magnet magnetic rack (Thermo Fisher Scientific) following the procedure proposed by the manufacturer. Agilent 2100 Bioanalyzer (Agilent Genomics) was used to determine the molar concentration of each barcoded library. Three equimolar pools of barcoded libraries were prepared: barcoded libraries from SUR-1 to SUR-6 (Pool 1), from SUR-7 to SUR-12 (Pool 2) and from SUR-13 to SUR-16 (Pool 3) were pooled together. The three pools were quantified on Agilent 2100 Bioanalyzer (Agilent Genomics) or Library TaqManTM Quantitation Kit (Thermo Fisher Scientific) following the procedure proposed by the manufacturer, and then diluted as proposed by the Ion PGM Hi-Q Chef Kit (Thermo Fisher Scientific).

For the amplicon sequencing, the Ion AmpliSeq Library Kit 2.0 (catalog # 4475345, ThermoFisher, Waltham, MA) and AmpliSeq Inherited Disease Panel (catalog# 4477686, ThermoFisher, Waltham, MA) were used in accordance with the manufacturer’s protocol. DNA from each genome was amplified in three separate primer pools, then these PCR products were combined for barcoding and library preparation. The concentration of the final library was measured with the Ion Library TaqMan Quantification Kit (catalog #4468802, ThermoFisher, Waltham, MA), then two libraries were adjusted to a concentration of 40 picomol/L and combined before chip loading. 318v2 BC chips (catalog #4488146, ThermoFisher, Waltham, MA) were loaded using the Ion Chef and then sequenced on the Personal Genome Machine using the Ion PGM Hi-Q Chef kit (catalog # A25948, ThermoFisher, Waltham, MA).

Library preparation was carried out using the Oncomine Assay™ (comprising the DNA Oncomine™ Focus Assay) (Thermo Fisher Scientific) following the manufacturer’s instructions, using a total of 10 ng input DNA per sample (minimum 0.83 ng/μL sample DNA concentration). A maximum of seven DNA samples were prepared per run on an Ion 318™ v2 chip (Thermo Fisher Scientific, catalog no. 4488150). The DNA panel can identify hotspot mutations in the following genes: AKT1, ALK, AR, BRAF, CDK4, CTNNB1, DDR2, EGFR, ERBB2, ERBB3, ERBB4, ESR1, FGFR2, FGFR3, GNA11, GNAQ, HRAS, IDH1, IDH2, JAK1, JAK2, JAK3, KIT, KRAS, MAP2K1, MAP2K2, MET, MTOR, NRAS, PDGFRA, PIK3CA, RAF1, RET, ROS1, and SMO; and K-RAS was the focus of this validation. Template preparation was performed on the Ion Chef System (Thermo Fisher Scientific, Waltham, MA, USA) using the Ion PGM Hi-Q Chef Kit and/or the Ion One Touch™ 2 System using the Ion PGM Template OT2 200 Kit. Sequencing was performed using the Ion PGM Hi-Q Sequencing Kit on the Ion Torrent Personal Genome Machine (Ion PGM).

Thirty-five Precision ID Ancestry Panel libraries were sequenced in pools containing 18 libraries (one library was not used in this study), which had been pooled in equimolar concentrations according to Qubit, TapeStation, or ABI7500 (IonLibQuant assay) quantifications. Each pool had a total library concentration of 50 pM. Template preparation consisting of emulsion PCR, enrichment of beads containing template, and chip loading was performed with the Ion Chef instrument and the Ion PGM Hi-Q Chef Kit according to the manual (Thermo Fisher Scientific). The loaded sequencing chips were placed onto the Ion PGM™ instrument (Thermo Fisher Scientific) together with Ion PGM Hi-Q Chef 400 Supplies Kit (Thermo Fisher Scientific) and sequenced for 500 cycles according to the manual. Sequence analysis was done using the Torrent Suite Software v.4.4.2 with the HID_SNP_GenoTyper v. 4.2 plugin. Linear regression and two-sided F test were performed using the “lm” application in R 3.3.0 to test for correlations between concentration estimates and library coverage using data from all 35 libraries and α = 0.05.

Before sequencing, the template preparation for library pools was performed either with Ion OneTouch 2 system (Thermo Fisher Scientific) using the Ion PGM™ Hi-Q™ OT2 Kit (Thermo Fisher Scientific) or Ion Chef system (Thermo Fisher Scientific) using the Ion PGM™ Hi-Q™ Chef Kit following the kit protocols. 2 µl of each 10 pM library was used for library pool, and 15–20 libraries were pooled together. 20 µl of a library pool was mixed with 5 µl of nuclease-free water and added to the amplification solution for template preparation. After the template preparation, the quality of resulting ion spheres was checked with Qubit 3.0 fluorometer (Thermo Fisher Scientific). Following quality check, the ion spheres were loaded on an Ion 318™ Chip (Thermo Fisher Scientific) and sequenced with Ion PGM system using Ion PGM Hi-Q Sequencing kit (Thermo Fisher Scientific) according to the protocol provided with the kit.

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.
