DNA & RNA Purification
PhasePrep™ BAC DNA Kit | ||
| Description: PhasePrep™ BAC DNA Kit offers a highly scalable, rapid, cost-effective method for isolating high molecular weight plasmids such as Bacterial Artificial Chromosomes (BACs) from recombinant E. coli cultures. Procedure: The kit utilizes a phase separation procedure that can be scaled to micro, mini, midi, or maxi prep sizes. Sufficient reagents are provided for 300 micro, 180 mini, 30 midi, or 15 maxi preps. Application: The purified BAC DNA contains very low levels of endotoxins and is ready for immediate use in Automated Sequencing (Figure 1), PCR, Restriction Enzyme Digestion (Figure 2), Cloning and other common applications. |

Sample Data
| High-quality BAC DNA for Automated Sequencing Figure 1. BAC DNA was purified with the PhasePrep BAC DNA Kit and sequenced with a custom primer using BigDye™ Terminator Chemistry. Sequencing reactions were resolved on an ABI 3700 sequencing instrument. Data provided by the Genome Sequencing Center at Washington University, St. Louis |

| Purified BAC DNA is suitable for restriction digestion Figure 2. Restriction digestion of BAC DNA isolated with the PhasePrep BAC DNA Kit and two other suppliers (C and Q). BAC DNA samples were purified from overnight cultures of E. coli HB101b transformed with a pbelloBAC11 clone. Approximately 1 µg of DNA from each sample was digested with 20 units of Eco R V at 37°C for 4 hours. One half of each digestion (approximately 0.5 micrograms) was separated by overnight electrophoresis in a 1% agarose gel. Lanes 1 to 8 were BAC DNA purified with Sigma kit, lane 9 was BAC DNA purified with Supplier C's kit, and lane 10 was BAC DNA purified with Supplier Q's kit. The molecular marker used at the first and last lanes was a 1kb DNA Ladder (M) (Product No. D0428). |
