Check if the same lab product or an alternative is used in the 5 most similar protocols
Fourteen barcoded specimens of Cornus-feeding Phyllocnistis spp. were screened for infection by Wolbachia spp. (Rickettsiaceae). The two genes, wsp and fbpA, were amplified with the three sets of primers: (1) wspecF (5’-CATACCTAT TCGAAGGGATAG-3’), wspecR (5’-AGCTTCGAGTGAAACCAATTC-3’) and (2) wsp81F (5’-TGGTCCAATAAGTGATGAAGAAAC-3’), wsp691R (5’-AAAATTAAACGCTACTCCA-3’), for the gene wsp (respectively 438 bp and ~600bp) and (3) fbpa-F1 (5’-GCTGCTCCRCTTGGYWTGAT-3’), fbpa-R1(5’-CCRCCAGARAAAAYYACTATTC-3’), for the gene fbpA (429 bp) to test for the presence of other Rickettsiaceae following the standard protocols (Baldo et al. 2006 (link), Kodandaramaiah et al. 2013 (link)).
PCR was run on a DNA-cycling machine 9800 Fast Thermal Cycler (Applied Biosystems – Foster City, CA). Gel electrophoresis was applied to visualise the amplified products in 1.5 % agarose gel using the gel electrophoresis apparatus (RunOne, EmbiTec, San Diego, CA). The gel was stained with ethidium bromide (EtBr) at a concentration of 0.5 μg/mL for 30 minutes (Lee et al. 2012 ), visualised in ultraviolet light source (wavelength 254 nm) and subsequently photographed using the image system IP-010.SD (Vilber Lourmat, France). The presence of the amplified transgene element on a gel was interpreted as evidence that the insect was infected with Wolbachia or related species parasite.

Genotyping Protocols for Genetic Comparison

Case-control comparisons for Oulu, Kuopio and Tampere cohorts were performed by High Resolution Melt (HRM) analysis (CFX96, Bio-Rad, Hercules, CA, USA) using Type-It HRM reagents (Qiagen, Hilden, Germany). A positive control was included in all analyses, and samples with differing melting curves were further confirmed by Sanger sequencing (ABI3130xl, Applied Biosystem, Foster City, CA, USA). The Helsinki cohorts were genotyped using Custom TaqMan SNP Genotyping Assays and TaqMan Genotyping MasterMix (ThermoFisher Scientific, Waltham, MA, USA). PCR was performed on 7500 Fast Real-Time PCR System or 9800 Fast Thermal Cycler and genotypes were analyzed on 7500 Fast System SDS software v1.3.1 or 7500 software v2.0.6 (Applied Biosystems, Waltham, MA, USA). Heterozygous carriers were included as positive controls in all analyses.

Multiplex PCR and CE-SSCA for BRAF and NRAS Mutation Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
BRAF and NRAS mutation analysis was performed on extracted DNA by multiplex PCR and capillary electrophoresis-single strand conformation analysis (CE-SSCA) using an in-house procedure. PCR was done using the 2720 Thermal Cycler (Applied Biosystems®, Foster City, USA) and the BRAF/NRAS mutational analysis was done using the ABI 3130XL Genetic Analyzer (Applied Biosystems®, Foster City, USA). For BRAF, a V600E mutation will result in a characteristic pattern in the CE-SSCA at all different temperatures and therefore requires no further confirmation by sequencing. For any unclear results, Direct DNA Sanger sequencing was performed for confirmation. For NRAS, any mobility shift identified by CE-SSCA in codon 61 or codon 12/13 was confirmed by Direct DNA Sanger sequencing. This was done using the 9800 fast thermal cycler (Applied Biosystems®, Foster City, USA) and the ABI 3500 Genetic analyzer (Applied Biosystems®, Foster City, USA). Sequencing data was analysed using Mutation Surveyor software.

Genomic DNA was independently extracted from each specimen of assembly 1. Specimens were grinded and processed with the QIAamp DNA Mini Kit (QIAgen, Germany) in accordance with the manufacturer’s instructions. DNA was eluted in 50 μL of PCR-grade water and stored at −20 °C.
The mitochondrial DNA target encompassing the cytb-nd1 region was amplified according to Latrofa et al. (2012 (link)) with minor modifications. Two microliters of DNA was used in a 25-μL final volume PCR reaction, including standard reaction buffer 2 mM MgCl2, 0.2 mM each dNTP, and 0.7 U of Thermus sp. DNA polymerase (Biotools, B&M Labs, Spain), and 15 pmol of each primer PhleF (5′-AAT AAA TTA GGA GGA GTA ATT GC-3′) and PhleR (5′-GCC TCG AWT TCG WTT ATG ATA AAT T-3′) (Sigma-Genosys).
Amplification was performed on a 9800 Fast Thermal Cycler (Applied Biosystems), standard ramp enabled, with the following conditions: initial denaturation of 5 min at 94 °C, 40 cycles at 94 °C for 1 min, 52 °C for 1 min, and 72 °C for 1 min, and final extension at 72 °C for 10 min. All the amplified products were resolved on 2 % agarose gels stained with Pronasafe Nucleic Acid Staining (Laboratorios CONDA, Spain) and visualized under UV light.

Total RNA was extracted using the Pure Link RNA Extraction Mini Kit (Ambion, Life Technologies), quantified in terms of concentration and purity with a nanodrop (Applied Biosystems), and reverse transcribed to cDNA using the High Capacity cDNA Reverse Transcription Kit (Applied Biosystems). Target genes (Table S1) were amplified in 20 μL reactions using 20 ng of cDNA, Fast SYBR Green Master Mix (Fisher Scientific), 500 nM primer concentrations, and an Applied Biosystems 9800 Fast Thermal Cycler. Relative gene expression was calculated using the delta‐delta Ct method (2−ΔΔCt) and normalized to ADMSCs on day 0 after encapsulation and the housekeeping gene GAPDH.
