Biofilm DNA Isolation Kit
Rapid and convenient method to isolate genomic DNA from different types of biofilm and biofilm forming-bacteria
No phenol or chloroform extractions
Yields high quality DNA that is ready for PCR and other downstream applications
Norgen’s Biofilm DNA Isolation Kit is designed for the rapid preparation of genomic DNA from biofilm. Genomic DNA is efficiently extracted from the biofilm by a combination of heat treatment, detergents and the use of provided Bead Tubes. The kit is able to remove known PCR inhibitors typically found within the biofilm, including humic acid. The purified genomic DNA is fully digestible with all restriction enzymes tested, and is completely compatible with downstream applications such as PCR and Southern Blot analysis. Preparation time for a single sample is less than 45 minutes, and each kit contains sufficient materials for 50 preparations.
Figure 1. High quality and yield of DNA from biofilm formed by two different species, Komagataeibacter xylinus (1-4), Komagataeibacter hansenii (5-8). Total DNA was isolated from 200 mg of biofilm using Norgen's Biofilm DNA Isolation Kit. For evaluation, 10 µL of each 100 µL DNA elution was run on a 1.2 % agarose gel. Note the high yield and quality of the DNA in all lanes. Lane M: Norgen's HighRanger 1 kb DNA Ladder (cat. 11900).
Figure 2. High DNA quality. DNA was isolated from a number of bioflim using Norgen's Biofilm DNA Isolation Kit. All DNA elutions isolated using Norgens Biofilm DNA Isolation Kit showed an excellent DNA quality indicating the consistent and robust performance of the Biofilm DNA Isolation Kit.
Figure 3. Amplification of bacterial cellulose synthesis (bcs), a gene from Komagataeibacter xylinus (circle) and Komagataeibacter hansenii (cross). From 100 µL elution, 5 µL of biofilm DNA was directly mixed to real-time PCR master mix (total reaction volume 20 µL), and the real-time SYBR Green PCR reaction was performed. The bcs gene was successfully amplified from the different samples without any inhibition and at the same Ct, indicating the excellent quality of biofilm DNA for downstream applications.
