For the rapid and efficient purification of DNA from exfoliated cells or bacteria in urine

  • Isolate genomic DNA from either exfoliated cells or bacteria found in urine
  • Isolate and detect genomic DNA from as little as 1 mL of urine and up to 50 mL urine
  • High quality DNA for sensitive applications
  • Rapid processing time

Urine DNA Isolation Kit for Exfoliated Cells or Bacteria

This kit provides rapid spin column purification of either: 1) human genomic DNA from exfoliated cells that have been shed into the urine from the urinary tract; or 2) bacterial genomic DNA from urine samples. It can process volumes between 1 to 50 mL of urine. The kit allows for the isolation of genomic DNA from both Gram-negative and Gram-positive bacteria or exfoliated cells. Multiple samples can be processed in 45 minutes (including a 30 minute incubation). Salts, metabolic wastes and proteins are removed to yield high quality DNA compatible with any application such as PCR, qPCR, methylation studies, sequencing and more.

Healthy humans generally have < 10, 000 CFU of bacteria per mL of urine, and this kit is sufficiently sensitive to isolate and detect DNA from even this minimal amount of bacteria

Storage Conditions and Product Stability

All solutions should be kept tightly sealed and stored at room temperature. These reagents should remain stable for at least 1 year in their unopened containers. This kit contains a ready-to-use Proteinase K solution which is dissolved in a specially prepared storage buffer. The Proteinase K is stable for up to 1 year after delivery when stored at room temperature. To prolong the lifetime of Proteinase K, storage at 2–8°C is recommended.
