Genome Sequencing of Pigment Mutants

Check if the same lab product or an alternative is used in the 5 most similar protocols
Genomic DNA was extracted from bacterial strains of interest using a Gentra PureGene DNA extraction kit (QIAGEN) with isolated DNA re-suspended in sterile water. Paired end sequencing was conducted by Eurofins Genomics using Illumina MiSeq V3 with 2 × 300 bp reads. Reads were mapped to the P. aeruginosa UCBPP-PA14 NC_008463.1 reference genome and delivered as BAM and BAI files. Further sequence analysis for SNP identification was conducted using the Integrative Genome Viewer software platform using the reference strain UCBPP-PA14 and the more recent PA14 Or genome sequence (NZ_LT608330.1). This Whole Genome Shotgun project has been deposited at DDBJ/ENA/GenBank under the accession SZXO00000000 (red pigmented mutant), SZXP00000000 (brown pigmented mutant), and SZXQ00000000 (yellow pigmented mutant).

To confirm the uninfected Wolbachia status of the Nasonia strains used, DNA was extracted using the Gentra PureGene DNA extraction kit (QIAGEN®), as well as a control infected strain (N. vitripennis 12.1). Verification of infection status was performed using PCR with the primers ftsZuniF and fts2uniR as previously described [25 (link)]. Individual adult Nasonia, n = 4 UT, n = 3 R3, and n = 3 13.2, n = 3 Wolbachia positive Nasonia - strain 12.1, were tested and no Wolbachia was detected in the UT, R3, or 13.2 strains.

A BALF supernatant aliquot from the two middle washes of the right middle lobe was centrifuged at 13,000 rpm for 10 min. Supernatants were profiled for 12 different bile acids as we previously described [14 (link)]. Microbial DNA was then extracted from the bacterial pellets using the Gentra PureGene DNA Extraction kit (QIAGEN) as per the manufacturer’s recommendations. To have an unbiased representation of the microbial DNA signatures in BALF, a minor modification was included, consisting of an overnight digestion with proteinase K.

DNA Methylation Profiling from Peripheral Blood

Check if the same lab product or an alternative is used in the 5 most similar protocols
Peripheral blood samples were collected at the eighth examination samples (2005 to 2008). Genomic DNA was extracted from buffy coat using the Gentra Puregene DNA extraction kit (Qiagen) and bisulfite converted using EZ DNA Methylation kit (Zymo Research Corporation). DNA methylation quantification was conducted in two laboratory batches. Methylation beta values were generated using the Bioconductor minfi package with background correction. Sample exclusion criteria included poor SNP matching of control positions, missing rate >1%, outliers from multi-dimensional scaling (MDS), and sex mismatch. Probes were excluded if missing rate >20%. In total, 2,635 samples and 443,304 CpG probes remained for analysis.

Transcriptomic Analysis of Canine Testicular Tissue

Adult Golden Retriever testes were obtained from routine castration procedures. Tissue samples were flash-frozen in liquid nitrogen and stored at −80°C. Genomic DNA was extracted using a Gentra Puregene DNA extraction kit (Qiagen), and RNA was extracted using an RNeasy fibrous tissue mini kit (Qiagen). Library preparation and NovaSeq S4 Illumina paired-end sequencing were performed at the UC Davis Genome Center. Reads were aligned to the CanFam3.1 reference assembly using minimap2 (Li 2018 (link)). PCR duplicate reads were removed, and the aligned files were sorted and indexed using SAMtools (Danecek et al. 2021 (link)). Evidence for chimeric transcripts in the RNA-seq data set was found through visual analysis of the retroCNV insertion sites and nearby genes in IGV. Because of the small sample size and heterogeneity of retroCNVs between individuals, evidence of expression was determined visually through examination of the insert site, the 5′ UTR of the parent gene, and insertion site genes for chimeric transcripts. For retroCNVs that contained any retroCNV-specific variants, the parent gene loci were examined for evidence of the retroCNV-specific variant, which would indicate expression of the retroCNV. A minimum of two discordant reads was used to consider a retroCNV expressed.

Whole genome DNA was extracted from clinical samples in CLS at KCCR or INH using the Gentra Puregene DNA extraction kit (Qiagen) with minor modifications of the manufacturer’s instructions as described in S1 Protocol [6 (link)]. DNA extracts were stored at 4–8°C (up to one week) or -18°C (long-term storage).
For routine on-site laboratory confirmation DNA extracts were subjected to IS2404 DRB PCR at KCCR and INH as previously described [6 (link), 10 (link), 35 (link)]. For comparative testing in the context of external quality assurance programs with conventional, gel-based IS2404 PCR (cPCR) [4 (link)–5 (link), 33 (link), 35 (link), 36 (link)] and a recently described modified IS2404 qPCR based on the assay published by Fyfe et al. [7 (link), 29 (link)] aliquots of DNA extracts were shipped to the Department of Infectious Diseases and Tropical Medicine (DITM), Munich, Germany by courier service at ambient temperature [10 (link)].

Genetic Variants in PTK7 and VANGL2

Check if the same lab product or an alternative is used in the 5 most similar protocols
DNA was extracted from newborn screening blood spots using the Gentra Puregene DNA Extraction Kit (Qiagen, Valencia, CA). The genomic structure of human PTK7 was determined using the NCBI GenBank (NT_007592.15, NM_001270398/ENST00000481273.5 and NP_001257327). The 20 exons of PTK7 were amplified by polymerase chain reactions (PCR) using primers flanking exon‐intron junctions. Primer sequences are available upon request. The PCR products were sequenced using the Prism Bigdye Terminator Kit (v3) on an ABI 3730XL DNA analyzer (Life Technologies, Carlsbad, CA). Both case and control samples were sequenced with either a specific forward or reverse primer. The detected variants were confirmed by repeating the PCR and re‐sequencing from both directions. VANGL2 was re‐sequenced in the 192 NTD cases following our previous publication (Lei et al., 2010). Sequencing results were analyzed using the Mutation Surveyor software V4.0.5 (Softgenetics, Stage College, PA).

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.
