Large DNA Fragments Kit (DFL100, DFL300)

Large DNA Fragments Gel Extraction Kit | Large DNA Fragments PCR Cleanup Kit
Large DNA Fragments Kit (DFL100, DFL300)

The Presto™ Max Gel/PCR Kit is a large DNA fragments Gel Extraction Kit and a large DNA fragments PCR Cleanup Kit in 1 convenient system optimized to recover or concentrate a broad range of DNA fragments (100 bp-50 kb) from agarose gel, PCR, or other enzymatic reactions. The Presto™ Max Gel/PCR Kit uses a concentrated sodium buffer to dissolve agarose gel and denature enzymes. Large DNA fragments are then bound by silica beads. Contaminants are removed with a Wash Buffer (containing ethanol) and the purified large DNA fragments are eluted by a low salt Elution Buffer, TE or water. Salts, enzymes and unincorporated nucleotides can be effectively removed from the reaction mixture without phenol extraction or alcohol precipitation. Typically, recoveries are up to 80% for Gel Extraction and up to 95% for PCR Cleanup. The entire procedure can be completed in 20 minutes and DNA can be eluted in (10-20 μl) of Elution Buffer to obtain a high concentration of DNA products. The purified DNA is ready for use in PCR, Fluorescent or Radioactive Sequencing, Restriction Enzyme Digestion, DNA Labeling and Ligation.  

Advantages (Cat. # DFL100, DFL300)

Presto™ Max Gel/PCR Kit Functional Test Data

Figure 1. Genomic DNA was extracted from 1x106 Hela cells using a traditional phenol-chloroform method combined with ethanol precipitation. 2 µg of extracted genomic DNA (30 kb) was then purified using the Presto™ Max Gel/PCR kit. The quality and concentration of genomic DNA was significantly increased following the purification process. M = Geneaid 1 Kb DNA Ladder
