Overview

Phage DNA Isolation Kit

Isolate high quality DNA from a broad variety of phage strains
High yields of total DNA
Fast and easy processing using a rapid spin-column format
No phenol or chloroform extractions or cesium chloride banding required
High yields of DNA recovered 3-15 µg DNA from 10⁶-10¹⁰pfu/ mL of enriched phages

This kit provides a rapid spin column method for the purification of total DNA from a broad spectrum of bacteriophages propagated in bacteria grown in liquid cultures. The DNA is isolated without the use of phenol, chloroform or cesium chloride banding procedures. The spin-column based procedure is rapid and can be completed in less than 45 minutes. The kit is highly efficient for processing small volumes of phage supernatant (500 µL – 1 mL) and with the optional DNase and Proteinase K treatments phage DNA yields are maximized while host DNA contamination is minimized. Purified total phage DNA is of the highest integrity, and can be used in a number of downstream applications including PCR, qPCR, Restriction Fragment Length Polymorphism (RFLP), sequencing, cloning, Southern Blot and more.

Supporting Data

Figure 1. Effective Host Genomic DNA Removal without Reducing Phage DNA Yield. Total DNA was isolated from four enriched phage cultures using Norgen's Phage DNA Isolation Kit. A DNase I pre-treatment was performed prior to adding the provided LysisBuffer. Briefly, 20 units of DNase I was added to 1 mL of enriched phage culture and the mixture was incubated at room temperature for 20 minutes. After the DNAase I treatment the procedure was followed. As a control, DNA was isolated from aliquots of the same 4 cultures using Norgens Phage DNA Isolation Kit without performing the DNase I treatment. For DNA analysis 10 µL of each 50 µL elution was loaded onto a 1X TAE agarose gel. As it can be seen, the phage DNA was safely protected from the DNase I treatment by its coat protein, while the host genomic DNA was efficiently degraded by the DNase I. Thus the DNase I pre-treatment resulted in less host gDNA contamination in the final phage elution without influencing the total phage DNA yield.

Figure 2. Optional Proteinase K Treatment Improves DNA Yield for Certain Phage Strains. Total DNA was isolated with and without the optional Proteinase K treatment using Norgen's Phage DNA Isolation Kit. Briefly, 4 µL of Proteinase K (20 mg/mL) was added to 1 mL of enriched phage culture and incubated at 55°C for 15 minutes withthe phage Lysis Buffer. After the Proteinase K treatment the procedure was followed. As a control, DNA was isolated from aliquots of the same 8 cultures using Norgen's Phage DNA Isolation Kit without performing the Proteinase K treatment. For DNA analysis 10 µL of each 50 µL elution was loaded onto a 1X TAE agarose gel and the yield of DNA was compared from the eight different phage types (lane 1 to 8). As it can be seen, the optional treatment of Proteinase K improved the phage DNA yield in Lanes 2, 5 and 6 dramatically. Lane M is Norgen's Highranger 1 kb DNA Ladder (Cat. 11900)
