Notes: Mineral accumulation was studied in Arabidopsis thaliana comparing loci involved with growing in soil versus hydroponics. An F2 population derived from a cross between Landsberg erecta (Ler; maternal parent) and Eringsboda-1 (Eri-1; paternal parent) was propagated by single seed descent for nine successive generations in soil.
The flower buds of three plants per line were collected, and the DNA extracted using the Wizard® Magnetic 96 DNA Plant System and used for genotyping with 90 amplified fragment length polymorphism PCR (AFLP) and 39 single sequence length polymorphisms (SSLP) markers to build a genetic map of quantitative trait loci (QTL). (4136)

After 72 hours, the neurons were harvested and used in various translation assays including ribosomal transit time. (4070)

Notes: To gain a better understanding of how Xylella fastidiosa causes diseases in grapes, the authors mutated conserved regulatory genes, including gacA, that affect expression of virulence-related factors in other species. The relative expression levels of gacA in wildtype and mutated strains were examined using RT-PCR. The authors also identified and quantified a number of genes that were regulated by GacA by microarray analysis. Microarray results were confirmed using RT-PCR. RT-PCR was performed using the AccessQuick™ RT-PCR System. (4052)

Notes: This study examined the genotype-phenotype correlation of the two major UGT isoforms, UGT1A1 and UGT1A6, involved in resveratrol metabolism. Genomic DNA was isolated from 30mg human liver tissue samples (normal and metastatic) using the Wizard^® SV Genomic DNA Purification System. The purified DNA was eluted with 65°C water and 200–400ng of eluted DNA was used in a PCR-RFLP UGT1A6 genotyping assay. Amplification was carried out using PCR Master Mix in a final volume of 50µl, and the amplimers digested with appropriate restriction enzymes. (4018)

Notes: The authors describe a new form of PCR, co-amplification at lower denaturation temperature PCR (COLD-PCR), to detect low-level somatic mutations. This technique is based on the facts that a) each DNA sequence has a critical denaturation temperature (T_c), which is lower than the melting temperature (T_m) and below which PCR efficiency decreases dramatically and b) Tc depends on DNA sequence. The authors used GoTaq^® Flexi DNA Polymerase and mutation-specific TaqMan^® probes for tumor protein 53 (TP53) and epidermal growth factor receptor (EGFR) to detect low-level somatic mutations in a mixture of wildtype and mutant DNAs. Conventional TaqMan^_® technology can detect mutant alleles at an abundance of 10–20% of that of the wildtype allele; using COLD-PCR the authors were able to increase selectivity 15- to 30-fold, detecting as little as 0.8% mutuant alleles. (4038)

Notes: This paper explored the effect of methyl-CpGmodified single-stranded oligonucleotides (ssODN) on gene repair. The Wizard^® Genomic DNA Purification Kit was used to isolate gDNA from methylCpG-ssODN-treated myoblasts derived from limb muscle of neonatal C57 mice that stably expressed the mismatch repair site. One microgram of purified gDNA was digested overnight with 5U of restriction enzyme, purified, resuspended in 20µl of water and 5µl used in real-time PCR to determine if the target had been repaired. (4062)

Notes: Glutathione levels were assessed in human coronary artery endothelial cells (HCAECs) as a measure of oxidative stress. HCAECs were treated with either 100ng/ml eotaxin, a newly discovered chemokine, or pretreated with 2µmol/l MnTBAP for 30 minutes followed by eotaxin treatment for 45 minutes. Positive controls were treatment with 10µg/ml antimycin A and 2ng/ml TNF-α. Cellular glutathione was measured using the GSH-Glo™ Glutathione Assay. (4011)

Notes: The authors examined the role of two promoters in the regulation of fabA, an enzyme involved in unsaturated fatty acid synthesis. fabA transcript levels were quantified using real-time quantitative RT-PCR using ImProm-II™ Reverse Transcriptase, followed by a SYBR^® Green method. (4053)

Notes: In this study, the authors wanted to examine the ability to trace the origin of tomato goods from fresh to processed. They tested several DNA extraction procedures for fresh tomato, tomato sauce, tomato puree, tomato pulp, whole peeled S. Marzano PDO (Protected Designation of Origin) tomato, whole peeled tomato, tomato concentrate and ‘‘Arrabbiata sauce”. Homogenized material (200mg) was extracted in three replicates using seven different methods including the Wizard^® DNA Clean-Up System. The DNA extracted was then analyzed by agarose gel electrophoresis, quantified and tested in PCR using SSR loci. The authors concluded that the Wizard^® DNA Clean-Up System was the most effective of the DNA extraction methods tested and yielded the greatest number of successful amplification reactions with lowest investment of personnel time and money. (4003)

Notes: This study examined the effects of folic acid supplementation on the offspring of pregnant rats fed a protein-restricted diet. Genomic DNA was extracted from rat adipose tissue using the Wizard^® SV Genomic DNA Purification System.

Notes: The authors use the Flexi^® Cloning System to convert their cDNA clones to expression-ready clones. They wanted clones that could be used for comprehensive analysis with the HaloTag^® Technology. They also describe a method of transferring ORFs between Flexi^® Vectors in a 96-well plate format. They also used Wizard^® SV 96 Plasmid DNA Purification, Wizard^® SV PCR Clean-Up, and Wizard^® SV Gel and PCR Clean-Up Systems. (4056)

Notes: The authors examined whether HMGB1 and HMGB2 proteins could affect promoter activity of the topoisomerase IIα gene. Portions of the topoisomerase IIα gene promoter were cloned into the pGL3 Basic Vector, and Saos-2 cells were cotransfected with the resulting constructs, an HMGB1- or HMGB2-expressing plasmid and the pRL-tk Vector as a control for normalization. Firefly and Renilla luciferase activities were determined using the Dual-Luciferase Reporter Assay. To determine whether HMGB1 and HMGB2 promoted binding of the transcription factor nuclear factor-Y (NF-Y) to the topoisomerase IIα promoter, the authors used a chromatin immunoprecipitation (ChIP) assay. Two populations of Saos-2 cells, one of which expressed HMGB1 or HMGB2 and one that had expression inhibited, were fixed with formaldehyde, then treated to shear chromatin. Immunoprecipitation was performed using an anti-NF-Y antibody, and the amount of DNA bound to the NF-Y was quantified by semi-quantitative PCR using GoTaq^® Hot Start DNA Polymerase and Green GoTaq^® Flexi Reaction Buffer. (4037)

Notes: These authors used short heteronuclear RNAs (shRNA) in multiple cancer cell lines to silence hypoxia-inducing factor-2α (HIF-2α), a gene that many cancers exploit to increase angiogenesis and activate fundamental receptor tyrosine kinase signaling pathways to gain growth signal autonomy. Western blotting and RT-PCR were used to monitor the level of HIF-2α silencing. RT-PCR was performed using the AccessQuick™ RT-PCR System. The authors also examined the level of tyrosine kinase activation in shRNA-treated cells by Western blot analysis. To examine levels of ERK1/2 phopshorylation, the authors used the Anti-ERK 1/2 pAb to compare levels of activated and unactivated ERK1 and 2. (4050)

Notes: The authors explored the role of a DNA replication factor, flap endonuclease I (FEN1), in regulating telomerase activity in mammalian cells. PCR was used to add a myc tag to the N terminus of FEN1 cDNA. The amplimer was gel purified, digested with NheI and SmaI, and cloned into the same sites in the pCI-neo Mammalian Expression Vector. The insert was confirmed by sequencing. (4030)

Notes: The researchers examined if a CD20 mutation would affect resistance to rituximab, an adjunct cancer therapy drug used for CD20-positive B-cell lymphoma. CD20 PCR products amplified from genomic DNA were cloned into the pTARGET™ Mammalian Expression Vector. These CD20 mutant constructs were stably introduced into K562 chronic myelogenous leukemia cells by electroporation and selected using G-418. One microgram of CD20 mutant construct DNA was transcribed and translated using an in vitro translation kit from Promega. (4032)

Notes: The authors used a HaloTag^® vector and the HaloCHIP™ System to identify a KLF15 binding site in the HSD17B5 promoter. (4059)

Notes: Because intestinal-type sinonasal adenocarcinoma (ITAC) and squamous cell carcinoma of the nasal cavity (SCCNC) are histopathologically similar to microsatellite-unstable colorectal adenocarcinoma or laryngeal squamous cell carcinoma, respectively, the microsatellite instability (MSI) state of the nasal tumors were of interest to researchers. Two nanograms of purified DNA from 41 ITACs and 24 SCCNCs were amplified for shifts in five mononucleotide microsatellite loci using the MSI Analysis System, Version 1.2. The multiplex PCR products were analyzed by capillary electrophoresis and noted as MSI positive if there was a size shift of at least one marker. (4117)

DNA was purified from ex vivo organs of female BALB/c mice infected with a murid herpesvirus-4 (MuHV-4) TK knockout using the Wizard^® Genomic DNA Purification Kit. Real-time PCR was used with 50–80ng of purified DNA to determine viral load of the animals. (4015)

Notes: The authors of this study used the HRE-CRE-luciferase reporter cell line (Glo-Response™ Cells) to test HSV constructs for activity.
