The E.Z.N.A.® Water DNA Kit is formulated to isolate high-purity cellular DNA from water samples typically containing humic acid and inhibitors of PCR. This kit uses a novel and proprietary method to isolate genomic DNA from variety of environmental samples. This kit has been successfully used to isolate DNA from tough-to-lyse bacteria, fungi, and algae that inhabit a range of samples including tap water, lake water, river water, and sewage samples. Isolated DNA can be used for most downstream applications including PCR, Southern blot, and SNP analysis.

  • Reliable – Reproducible DNA purification from variety of sample sources
  • High quality – Inhibitor Removal Technology provides efficient PCR inhibitor removal
  • High yield – Efficient purification of DNA from even specialized samples

Genomic DNA purified using the E.Z.N.A.® Water DNA Kit. Purified genomic DNA from 7 different water sources was isolated with the E.Z.N.A.® Water DNA Kit. DNA was extracted in duplicate from water samples as follows: sample 1 from 20 L tap water, sample 2 from 5 L air conditioner water, sample 3 from 3 L spring water, sample 4 from 2 L sanitary waste water, sample 5 from 5 L lake water, sample 6 from 6 L pool water, and sample 7 from 3 L industrial sewage water. Genomic DNA (30% of total purified DNA) was analyzed on a 1% agarose gel to demonstrate yield and quality of the DNA. M: Lambda Hind III DNA Marker.
