Profile

• Separating DNA by gel electrophoresis then visualizing the bands under a UV-transilluminator.
• Excising the desired sample band with a razor and/or tweezers.
• Transferring the sample band to a test tube for subsequent purification steps.

The x-tracta from LabGadget has evolved beyond historical and first generation gel extraction tools to provide disposability with one-handed operation. The proprietary cutting blade and ergonomic design means that extractions can be performed in a rapid two-step process with great accuracy and precision.
