- Simple: Fastest workflow (= 20 minutes).
Description
The Quick-DNA Fungal/Bacterial Midiprep Kit is designed for the simple and rapid isolation of DNA from tough-to-lyse fungi, including A. fumigatus, C. albicans, N. crassa, S. cerevisiae, S. pombe, as well as Gram (+/-) bacteria, algae, and protozoa. The procedure is easy and can be completed in minutes: fungal and/or bacterial samples are rapidly and efficiently lysed with our state of the art, ultra-high density BashingBeads. Zymo-Spin column technology is then used to isolate the DNA that is ideal for downstream molecular-based applications including PCR, array, etc.

Product FAQ
Q1: Are there any tips in optimizing bead beating conditions?
We have validated our kits with both high-speed homgenizers and low-speed disruptors. We highly recommend users to optimize their bead beating conditions for their own instruments. We recommend using a 50 ml-tube adapter to ensure that the bead beating is efficent (do not use adapters made of foam). For high-speed homogenizers, we recommend a total of 5 mins bead beating (1 min interval at 6.5 m/s with 5 mins rest, repeat 5 times). For low-speed cell disruptors, we recommend 30 mins at max speed.
Q2: My lysate seems viscous. What is causing this to happen? How can I fix this?
A viscous sample can indicate incomplete sample lysis. Try using less of your sample and optimize bead beating conditions (duration, speed, time) to ensure samples are thoroughly lysed. After bead beating, pellet the cell debris before moving on. Adding more Genomic Lysis buffer to the lysate can help dilute and deproteinate the sample, making the sample less viscous and more suitable for DNA recovery.
Q3: Is it necessary to add beta-mercaptoethanol? Can this step be substituted or omitted?
Addition of beta-mercaptoethanol is recommended to enhance sample lysis, but can be substituted with dithiothreitol (DTT, final concentration of 10 mM). However, if bead beating is optimized and lysis is efficient, the addition of BME is not necessary and can be omitted.
Q4: When can an RNase A treatment be implemented in the protocol?
No additional RNase A treatment is required when processing samples within kit capacity. The selective chemistry allows for binding of double stranded DNA to the column and for RNA to flow through.
