is a proprietary lysis buffer used primarily in QIAGEN DNA extraction kits (such as the DNeasy Blood & Tissue Kit ). In the context of molecular biology, "ATL" stands for A lkaline T issue L ysis.
Buffer ATL typically contains a detergent (often an ionic detergent like SDS) and buffering agents. buffer atl qiagen
It is essential to vortex Buffer ATL thoroughly before use to ensure a homogeneous mixture, especially if it has been sitting for a while. is a proprietary lysis buffer used primarily in
: Acts as a potent lysis buffer to break down cell membranes and release nucleic acids into solution. It is essential to vortex Buffer ATL thoroughly
| Issue | Possible Cause | Solution related to Buffer ATL | | :--- | :--- | :--- | | | Incomplete Lysis | Increase incubation time with Buffer ATL + Proteinase K. Ensure tissue was cut small enough. | | Clogged Column | Too much debris | Centrifuge the lysate after Buffer ATL digestion to pellet debris, then transfer supernatant to the column. | | Degraded DNA | Nuclease activity | Ensure Buffer ATL volume is correct to create the proper osmotic pressure; ensure Proteinase K was added immediately. |
