Genotyping of AF-associated SNVs

Check if the same lab product or an alternative is used in the 5 most similar protocols
For all participants, DNA was extracted from peripheral blood samples using the commercially available innuPREP Blood DNA Mini Kit (Analytik Jena AG, Jena, Germany) [9 (link)].
Eight SNVs previously reported to be associated with AF in genome-wide association studies (GWAS) and with a minor allele frequency (MAF) of >5% in Europeans (gnomAD v.2.0.1) were selected for genotyping (Table 1). The selected SNVs were not in strong linkage disequilibrium.
Genotyping was carried out by real-time PCR and high-resolution melting analysis using Rotor-Gene Q (QIAGEN N.V., Venlo, The Netherlands), as described previously [9 (link)]. Primers are available upon request. To confirm the genotyping results, 8–16 samples with different genotypes were randomly selected for Sanger sequencing using the BigDye Terminator Kit v3.1 (Thermo Fisher Scientific, Waltham, MA, USA).

Rapid Genomic DNA Extraction from Blood

Check if the same lab product or an alternative is used in the 5 most similar protocols
Genomic DNA was extracted from whole blood using the innuPREP Blood DNA Mini Kit from Analytik Jena, Upland, CA, USA) (Catalogue No: AJG#845-KS-1020050). This kit allows the rapid isolation of genomic DNA from EDTA blood samples. The extraction procedure is based on the lysis of the blood sample followed by the binding of the nucleic acids onto the spin filter membrane. After several washing steps, the nucleic acids are eluted from the membrane using elution buffer. The samples were checked for purity and concentration after the extraction procedure. Samples with good purity and concentration were stored under −20 °C until PCR was performed.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Genomic DNA was isolated using innuPREP Blood DNA Mini kit (Analytik Jena, Jena, Germany) according to the manufacturer’s instructions. The methylation profile of the proximal Il36a promoter was performed by bisulphite sequencing as described previously with minor modifications [49 (link)]. In brief, 4 μg of genomic DNA was digested with BglII, purified by phenol-chloroform extraction and 500-1000 ng digested DNA was bisulphite-converted as described. Primers were designed using Methyl Primer Express® Software v1.0 (Applied Biosystems/ThermoFisher Scientific) to amplify specific regions of the genome following bisulphite conversion. The Il36a promoter region from −439 to −112 relative to the transcriptional start site on the (-)-strand was amplified using the primers Il36a_BSP_for (5′-GGAGGGTTTGTTAAGTATTTGT-3′) and Il36a_BSP_rev (5′-AATATCCACTAAAATCAACCTAAAA-3′). For bisulphite sequencing, PCR products were gel-purified and cloned into the pCR2.1-Topo Vector System (ThermoFisher Scientific) and sequenced using the M13rev primer (5′-CAGGAAACAGCTATGAC-3′). Sequencing results were analyzed using QUMA software [50 (link)]. Samples with conversion rate < 90% and sequences identity < 70% were excluded from the analysis. The minimum number of clones for each sequenced condition was ≥10.

Genomic DNA was obtained from 250 μL of EDTA- anticoagulated venous blood using innuPREP Blood DNA Mini Kit (Analytik Jena AG, Germany), according to the manufacturer's recommendations. For SNP genotyping, we used a set of reagents from TaqMan® SNP Genotyping Assay (Applied Biosystems, USA): C__11592758_10 (rs6264), C___2184734_10 (rs5443), C___1202883_20 (rs1801133), C___3084793_20 (rs429358), and C____904973_10 (rs7412). The In/Del ACE gene polymorphism was determined as described previously 7 (link), 8 (link).

DNA-Compound Interaction Spectroscopy

The interaction with DNA of the test compound was studied by using the UV spectrophotometer method reported in literature with small modifications [32 (link)]. In this assay, an innuPREP Blood DNA Mini Kit (Analytik Jena) (AJ Innuscreen GmbH, Berlin, Germany) was used for the extraction of genomic DNA from human blood. The assay was conducted on a PDA spectrophotometer (Agilent 8453) Agilent Technologies, Inc., UK. Methanol and water, in a ratio of 9:1, were used as a blank and solvent to dissolve the compounds. The spectrum of the pure compound was recorded, and, to this, DNA was added in different concentrations, step wise, starting from lowest concentration to higher concentrations, keeping the compound concentration in the reaction mixture constant. The absorbance measurements were recorded by a UV-visible spectrophotometer by keeping the concentrations of compounds constant (100 µM) in the sample cell while varying the concentrations of DNA (0.5 × 10−6 to 1 × 10−6, 0.5 × 10−5 and 1 × 10−5 M) in the sample cell. The spectra were recorded in the form of spectral peaks in each step and the change in the absorbance was noted. To achieve an equilibrium between the compound and the DNA, the solutions were allowed to stay for at least 5 min before each measurement was made.

Melting points were determined in open capillaries on a FALC Instrument SRL360D. TLC (Silica Gel 60 F254) from Merck (Beijing, China) was used to check the compounds’ purities. Elemental analyses were carried out by using Euro EA 3000 (EUROVECTOR, Pavia, Italy) instrument. The infrared spectra of the Schiff bases were recorded on FT-IR (Bruker Optics GmbH & Co. Ettlingen, Germany) with an ATR model (ALPHA 200488) in the frequency range of 4000–550 cm–1. NMR spectra were recorded in DMSO-d6 and CDCl3 solvent on a BRUKER AV-500 MHz NMR (Bruker Beijing Scientific Technology, Beijing, China). A high-resolution multinuclear FT-NMR spectrometer was used in the presence of SiMe4 (internal standard) at δ = 0 ppm at 25 °C.
The sbsorbance of α-amylase and α-glucosidase activities (at 540 and 405 nm, respectively) were measured on a microplate reader (BioTek Elx-800, Agilent Technologies, Santa Clara, CA, USA). An InnuPREP Blood DNA Mini Kit (Analytik Jena) (AJ Innuscreen GmbH, Berlin, Germany) was used for the extraction of genomic DNA from human blood. A PDA spectrophotometer (Agilent 8453) Agilent Technologies, Berkshire, UK, along with a quartz optical cell (with an effective absorption path of 1 cm), was used for DNA interaction studies of the synthesized Schiff bases.

Genomic DNA was isolated from blood samples, taken in ethylenediaminetetraacetic acid, using an innuPREP Blood DNA Mini Kit (Analytik Jena AG, Thuringia, Germany). Determination of the SOD and CAT polymorphisms was achieved by restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR) analysis using the primers and the restriction enzymes shown in Table 1. PCR was carried out in a final volume of 25 µL, using 1 µL 100 ng genomic DNA, 0.2 U Taq DNA polymerase (Analytik Jena AG), 2.5 µL 10X buffer, 0.2 mM dNTP, 0.4 µM of each of the primers, and 1.5 mM MgCl 2 . PCR cycles were carried out in a DNA Thermal Cycler (MultiGene, Labnet) according to the following program: an initial denaturation of DNA at 94°C for 5 min; 35 cycles of 1 min at 94°C; 30 s at 59°C, or 57°C, or 60°C to detect Cu/Zn-SOD +35 A/C, Mn-SOD T47C, or CAT -21 A/T polymorphisms, respectively; and 45 s at 72°C. A final extension was performed at 72°C for 7 min. The resulting PCR products were digested with the corresponding restriction endonucleases: 5 U HhaI (Thermo Scientific), 2.5 U BsawI (New England BioLabs), and 5 U HinfI (Jena Bioscience) according to the manufacturer recommendations. Digestion products were analyzed electrophoretically on 3% agarose gel stained with ethidium bromide.

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.
