Product Description
By combining the stringency of CTAB lysis with the speed and ease-of-use of silica-membrane purification, ISOLATE II Plant DNA Kit provides a fast method for the purification of high-quality genomic DNA from most plant cells, particularly those rich in polysaccharides, including leaves, bark, roots and fruits as well as dung, animal-fecal, soil and compost samples.
Some plant tissues do not lyse well in CTAB and so an SDS-based lysis buffer is also provided as an alternative. Residual amounts of RNA remaining can be removed using RNase treatment during lysis with the RNase A supplied in the kit.
ISOLATE II Plant DNA Kit shows excellent recovery of plant DNA when different homogenization techniques are used. The silica membrane in the columns is optimized to improve DNA binding to give high-yields of high-quality DNA, even from difficult samples such as freeze-dried budding leaves. The extracted DNA is ready to use for subsequent downstream reactions such as PCR.
ISOLATE II Plant DNA Kit has been designed to deliver optimal performance in qPCR in tandem with SensiFAST Real-Time PCR Kits and in end-point PCR with MyTaq DNA Polymerase.
Applications
- qPCR
- End-point PCR
- Southern, dot and slot blotting
- Genotyping
- Restriction digestion
- Next generation sequencing
- Bisulfite conversion/methylation analysis

ISOLATE II Plant DNA KitIsolating DNA from soil samples is a big challenge because samples are full of inhibitors like polymers or low-molecular substances, which inhibit downstream applications. Therefore, it is difficult to find a kit which can deliver stable DNA. The ISOLATE II Plant DNA Kit is able to handle these kinds of samples and worked well for soil samples.

FAQs
Both lysis buffers PA1 and PA2 can possibly become cloudy, if they are stored under 20°C. They contain CTAB (PA1) and SDS (PA2) which can precipitate. After a short incubation at 37°C for several minutes they should become clear again.
For the optimal recovery of large RNA/DNA fragments it is necessary to optimize the elution step. To increase the recovery rate it would be helpful to use a larger volume for elution, incubate the column with the elution buffer prior to centrifugation and use repeated elution steps. To avoid excessive dilution it may be helpful to reapply the eluted fraction again. Furthermore it could be helpful for DNA elution to heat the elution buffer to 70°C.
