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 uses 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.

Beneficial Features

5, 40, 250 or 500 ml overnight culture for micro, mini, midi or maxipreps, respectively
Yield Typical DNA yields of 2 - 100 µg from 5 - 500 mL of overnight cultures
Speed Less than 1 hour; no tedious gravity-flow columns
Safe No phenol/chloroform extraction required
Versatile Allows possible micro to maxi preps with the same kit

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 our 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 1 kb DNA Ladder (M) (Product No. D0428).
