ISOLATE II Genomic DNA Kit

ISOLATE II Genomic DNA Kit provides a simple, efficient column-based method for the isolation of genomic DNA from a wide variety of materials, without the need

ISOLATE II Genomic DNA Kit

Fast – streamlined protocol for consistent recovery of genomic DNA in as little as 20 minutes

High-performance – extraction of high-purity DNA, ideal for use in all downstream applications

High-yield – efficient sample lysis and column-binding for high-yield recovery of genomic DNA from limiting amounts of sample

Flexible – reliable extraction of genomic DNA from a very broad range of human, animal and microbial samples

Excellent results from a variety of samples

Genomic DNA was isolated in duplicate from E. coli, mouse tail, mouse lung, HeLa cells and 3T3 cells, using ISOLATE II Genomic DNA Kit (lanes 1-5 and 6-10 respectively) and used to amplify a fragment of the Rn 18s gene. The results illustrate the consistency between replicates and between completely different species.

Consistency between species

Genomic DNA was isolated from hair samples of eastern lowland gorilla, western gorilla, northern plains gray langur, white-headed langur and red-shanked douc (lanes 1-5 respectively). Genomic DNA was isolated using ISOLATE II Genomic DNA Kit and a fragment amplified to illustrate the consistency in quality, purity and yield of the DNA extracted.

Product Description

By combining Proteinase K lysis with the speed and convenience of silica membrane purification, ISOLATE II Genomic DNA Kit provides a fast method for the purification of high-quality genomic DNA from a variety of starting materials.

By combining Proteinase K lysis with the speed and ease-of-use of silica-membrane purification, the ISOLATE II Genomic DNA Kit provides a fast method for the purification of high-quality genomic DNA from a variety of starting materials, such as mouse or rat tails, bacteria, yeast, dried blood spots, genomic/viral DNA from blood, hair follicles, paraffin-embedded issue (FFPE), insects, dental swabs, buccal swabs, stool viruses (e.g. CMV), Mycobacterium tuberculosis or Legionella pneumophila in sputum or bronchoalveolar lavage, EHEC bacteria in food, bacterial DNA (e.g. Chlamydia trachomatis) from cultures, biological fluids or clinical specimens, bacterial DNA (e.g. Borrelia burgordferi) and viral DNA (e.g. CMV) from urine.

ISOLATE II Genomic 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.

FAQs:

ISOLATE II Genomic DNA Kit

Can I use columns or solutions from one kit in another one?
The columns supplied with the ISOLATE II kits may appear similar, but each type has been optimized to work within the buffer system supplied with the corresponding kit. The swapping of columns (or buffers) between kits may lead to no recovery of nucleic acid whatsoever, or at the very least severely impaired purification.
Is it possible to interrupt the DNA or RNA extraction protocols?
Interruption of the DNA/RNA extraction process is possible after the sample lysis only. It is possible to homogenize and lyse the samples and to store them in the freezer until use for RNA extraction. RNA clean up with a column cannot be interrupted and we recommend to avoid delays during the column purification process. If a delay is unavoidable the columns should be stored on ice.
The sequencing protocol I am using says that I have to have my DNA suspended in pure water. Do I have to use the elution buffer supplied with the kit?
The elution buffer is ideal for applications such as restriction enzyme digestion, sequencing and PCR. It is possible to use DNase-free water for elution, but you should expect a slightly lower yield.
Does the elution buffer of the DNA extraction kits contain EDTA? I am afraid this may impair my downstream applications.
The elution buffer of this kit does not contain EDTA which could interfere with downstream applications like PCR or sequencing.
Which one is the recommended kit or protocol for hard to lyse bacteria (e.g. gram positive bacteria)?
The ISOLATE II Genomic DNA Kit provides a protocol for hard to lyse bacteria (see sec 9.2). Also the ISOLATE II Plant DNA kit could be suitable, because the optimized lysis buffer from this kits may be also be used for processing these difficult to lyse bacteria. In general, it is necessary to optimize the lysis step with the appropriate mechanical, enzymatic or chemical methods recommended for this kind of sample. Please refer to the related literature or ask the Meridian technical support for further suggestion.
What do I need to consider for the clean-up of large fragments or PCR products?
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.
