I-Blue Midi Plasmid Kit

Model Number IB47180

$42.68

Advanced Plasmid Kits for Mid-Scale DNA Purification:

The I-Blue Midi Plasmid Kit uses pre-packed anion-exchange resin columns to purify plasmid DNA from 50 – 150 ml of cultured bacterial cells. Included with the kit is the I-Blue Lysis Buffer, an optional color indicator to prevent common handling errors, ensuring efficient cell lysis and neutralization. Utilizing a modified alkaline lysis method and RNase treatment, this kit provides clear cell lysate with minimal genomic DNA/RNA contaminants. Upgrade your lab's capabilities with one of the most reliable plasmid kits available.

Additional Item Description:

I-Blue lysis buffer is added during the cell re-suspension step, then PM2 buffer is added. After the addition of the PM2 buffer the sample will begin to turn blue during mixing, when the sample is completely blue complete lysis has been achieved. Colorless areas or brown clumps indicate incomplete lysis and mixing should continue until the sample is entirely blue. During the neutralization step, PM3 buffer is added and shaking the tube vigorously will begin to turn the sample back to a neutral color. Once the sample is completely colorless, neutralization is complete. Due to the high efficiency of the Midi Column, the entire procedure can be completed in 80 minutes without ultracentrifuges, HPLC, or other toxic reagents. The purified plasmid DNA is suitable for transfection, sequencing reactions, ligation, PCR, in-vitro transcription, microinjection, restriction enzyme digestion, and gene gun.

The quality of the I-Blue Midi Plasmid Kit is tested on a lot-to-lot basis, by isolating plasmid DNA from a 50 ml overnightE. coli(DH5α) culture, containing pBluescript (A600>2U/ ml). Following the purification process, a yield of more than 250 µg is obtained and the A260/A280 ratio is between 1.8-2.0. The purified plasmid (1 µg) is used in EcoRI digestion and analyzed by electrophoresis.
