Simplifying Nucleic Acid Preparation with STRATEC Technology
Nucleic acid isolation is one of the most basic techniques performed in every molecular biology lab, yet it is vitally important for the success of all downstream applications. What AS ONE International offers is much more than just another alternative for nucleic acid isolation: the proprietary technologies from Stratec Molecular enable higher quality nucleic acid purification in less time.
At the core of Stratec products is the unique non-chaotropic chemistry. Unlike traditional buffers that contain denaturing (chaotropic) ions such as guanidinium, Stratec uses non-chaotropic ions in most of its DNA purification products. There are three major advantages to this chemistry:
- Faster protocols:non-chaotropic conditions enable binding of nucleic acids in very low salt concentrations, which in turn require fewer washing steps
- Higher DNA yield:non-chaotropic buffers do not degrade lytic enzymes, resulting in better sample lysis
- More intact DNA:a more “gentle” chemical environment is less damaging to DNA and maintains sample integrity
Based on this proprietary chemistry, Stratec has developed additional product features for a variety of applications, as shown below.
MSB – Minimal Salt Binding
The MSB technology allows fast purification of DNA fragments from PCR, cDNA synthesis, or restriction enzyme digestion in just two steps: 1) Binding and 2) Elution. No washing step is required since DNA binding to membrane occurs at extremely low salt concentrations.
- Purify DNA fragments from 80 bp to 30 kbp
- 80-95% recovery
- Elution volume as low as 10 µl
- Less pipeting and plastic waste

RTP – Ready to Prep
The RTP technology streamlines the processing of pathogen-containing samples. All reagents required for DNA/RNA preparation – including lysis buffer, proteinase, and carrier nucleic acid are provided as a lyophilized master mix in a single extraction tube. Simply add the sample to initiate the extraction process.
- Minimal contact with infectious sample
- Faster workflow via reduced pipetting & handling
- Extraction tube stable at room temperature
