Notes: The authors identified a bacterial strain that can use the toxin 3-nitropropionic acid (3NPA) as its sole carbon and nitrogen sources and cloned the genes that encode the enzymes responsible for the initial steps in the 3NPA degradation pathway. The Pseudomonas library used to clone these genes was created using genomic DNA isolated using the Wizard^® SV Genomic DNA Purification System. Closely related genes were amplified from other bacterial species for phylogenetic analysis. PCRs were performed using the GoTaq^® Hot Start Polymerase. (4164)

Notes: To study how chemotherapy affects hair follicles (HF), the researchers microdissected and cultured human anagen VI scalp follicles and treated the cells with 4-Hydroperoxycyclophosphamide (4-HC) at similar concentrations to those received during therapy. After incubation for 24 hours with 30µmol/L of 4-HC, the HFs were homogenized and genomic DNA was purified using the Wizard^® SV Genomic DNA Purification System. To determine if the treatment induced the mitochondrial common DNA deletion, the isolated DNA was subjected to real-time PCR.

Notes: The authors explored the possibility of a domain-based level of gene expression regulation for chromosomes by integrating the green fluorescent protein (GFP) reporter in 90 different locations in cultured human cells. This integration was accomplished by infecting human embryonic kidney cells (HEK293) with a lentiviral construct carrying the GFP gene under the control of the ubiquitously expressed human phosphoglycerate kinase (PGK), sorting GFP-positive cells by FACS and selecting clones for expansion. Genomic DNA was isolated from the various clones using the Wizard^® SV Genomic DNA Purification System and analyzed by PCR or restriction digested for Southern blotting. (3743)

Notes: A panel of 11 Gram-negative and 11 Gram-positive bacterial species was used to develop a real-time PCR detection method. Initially DNA was purified from 1ml of various dilutions of bacteria resuspended in a saline solution using either the QIAamp DNA blood mini kit or the Wizard^® SV Genomic DNA Purification System. The results suggested that the Wizard^® SV Genomic DNA Purification System extraction protocol was superior in disrupting the bacterial cell wall (especially of Gram-positive bacteria), to allow release of bacterial DNA. Using DNA purified with the Wizard^® SV Genomic DNA Purification System, detection of S. aureus and E. coli at concentrations as low as 10¹ CFU per PCR was achieved. The Wizard^® SV Genomic DNA Purification System purification protocol provided in eNotes online (www.promega.com/enotes/applications/ap0051_tabs.htm) was used with the following modifications: The bacterial pellet was resuspended in 400µl of enzymatic lysis solution (47mM EDTA, 25mg/ml lysozyme, 20µg/ml lysostaphin) and incubated for 2 hours at 37°C. Next, 19.2mg/ml proteinase K was added (final concentration 0.4mg/ml), and the mixture was incubated for 1 hour at 55°C. Finally, the Nuclei Lysis Solution and RNase Solution were added, mixed and incubated for 10 minutes at 80°C. For real-time PCR analysis, 2µl of genomic DNA was used. (3676)
