DNA Cleanup Maxi Kit (DFM010, DFM025)
GenepHlow™ DNA Cleanup Maxi Kits were designed to recover or concentrate DNA fragments from large volume agarose gel, restriction enzyme digestion or PCR reaction products. Gel/PCR Buffer (yellow color indicating optimal pH≤7.5) is premixed with a pH indicator to ensure optimal pH, facilitate DNA binding and allow for easy observation of undissolved agarose gel. If pH exceeds the optimal level (>7.5), the color of the solution will appear purple instead of yellow. 3M Sodium Acetate (pH5.0) which is included with the kit, can then be added to the solution to adjust pH and return the color to yellow. Chaotropic salt is used to dissolve agarose gel and denature enzymes while DNA fragments are bound by the glass fiber matrix of the spin column. Contaminants are removed with a Wash Buffer (containing ethanol) and the purified DNA fragments are eluted by a low salt Elution Buffer, TE or water. The pH indicator, salts, enzymes and unincorporated nucleotides can be effectively removed from the reaction mixture without phenol extraction or alcohol precipitation and the purified DNA is ready for use in subsequent reactions.

Quality Control

The quality of the GenepHlow™ DNA Cleanup Maxi Kit is tested on a lot-to-lot basis according to Geneaid's ISO-certified quality management system. DNA fragments are purified from either agarose gel, restriction enzyme digestion products, PCR products or other aqueous solutions analyzed by electrophoresis.

GenepHlow™ DNA Cleanup Maxi Kit Functional Test Data 
Figure 1. 200 µg of pbluescript plasmid DNA was digested by Hind III endonuclease at 37ºC for 2 hours. Following digestion, the linear DNA fragment was purified using the GenepHlow™ DNA Cleanup Maxi Kit. The unpurified DNA fragment (lane 1) and 3 replications of 5 µl purified linear DNA fragments (lanes 2-4) were loaded on 0.8% agarose gel. M = Geneaid 1 Kb DNA ladder

Optimal pH  
pH Too High
Figure 2. A pH indicator is premixed with the binding buffer to ensure optimal pH, facilitate DNA binding and allow for easy observation of undissolved agarose gel. If pH exceeds the optimal level (>7.5), the color of the solution will appear purple instead of yellow. 3M Sodium Acetate (pH5.0), which is included with the kit, can then be added to the solution to adjust pH and return the color to yellow.
