Nanosep® Centrifugal Ultrafiltration Devices: Uses for Cloning and PCR

Download Application Note

Cloning involves insertion of genetic sequences in plasmids using techniques as restriction digest and PCR. However, traditional cloning techniques bring with it problems such as:


  • Carry-over of salts and residual ethanol or other organic solvents that can inhibit downstream enzymatic reactions
  • Multiple purification steps, each associated with significant product losses


Use of Nanosep centrifugal ultrafiltration devices in various steps of the cloning process offers the following benefits:


  • Avoids retention of components such as ethanol or other organic solvents that may inhibit enzymatic activity
  • High-yield rapid recovery of dilute DNA samples through reduced manipulations


We present a method for cloning PCR products or other DNA fragments that utilizes a single Nanosep centrifugal device and provides significant reductions in time, labor, and materials over classical methods.
