The oasig freeze drying process stabilises all of the active components allowing these reagents to be shipped and stored at room temperature. This hugely simplifies the logistics of purchasing, shipping and using the technology. Whether you are in a sophisticated laboratory in Texas or a mobile field hospital in Timbuktu we can supply complete qPCR kit and reagent packages to your door quickly and cheaply via standard shipping methods without the need for dry ice or a cold chain of any sort.
The performance of the reagents is second to none. We are confident that you will find excellent data quality and even see an improvement in data quality versus many traditional frozen master mixes.
Primerdesign real-time PCR reagents are manufactured to the highest standards within our ISO9001:2008 and ISO13485:2012 certified quality management laboratory environment.

Product Info
Permagen’s 16 x 1.5 mL Microfuge Tube Magnetic rack is designed for magnetic bead separations from up to 16 tubes
Contains the strongest magnets out of all of our Microfuge racks
Tubes are pushed 14mm between centers allowing the use of an 8-channel, adjustable head pipette. 8 tubes per side also make for easy transition to and from microplates
Accommodates many common 1.5 mL Microcentrifuge and some 2.0 mL tubes
Tubes are angled and beads will be pulled to back wall allowing easy aspiration and tip tracking down the front wall of the tubes without disturbing bead pellet
HiPure Gel Pure DNA Kit uses proprietary chemistry and HiPure technology to recover DNA fragments between 60bp-10kbp with yields exceeding 80%. DNA is suitable for ligations, PCR, sequencing, restriction digestion, or various labeling reactions. In addition, this kit can be also used to recover DNA directly from enzymatic reactions such as PCR and enzyme digestion reactions.

Principle
The HiPure system uses a simple bind-wash-elute procedure. Gel slices are dissolved in a buffer containing a pH indicator, allowing easy determination of the optimal pH for DNA binding, and the mixture is applied to the column. Nucleic acids adsorb to the silica-gel membrane in the high-salt conditions provided by the buffer. Impurities are washed away and pure DNA is eluted with a small volume of low-salt buffer provided or water, ready to use in subsequent applications.
Advantages
High recovery efficiency – ≥80% DNA recovery
General – recover DNA from gel or enzyme-driven reaction solutions such as PCR
Fast – isolation can be completed in 10-15 minutes by column gel method
Great cost-effectiveness performance

Principle and Interpretation
Tryptone, proteose peptone, meat extract, yeast paste powder provide nitrogen sources, vitamins, amino acids, and growth factors; sodium chloride can maintain a balanced osmotic pressure; sodium dihydrogen phosphate and potassium dihydrogen phosphate as buffering agents; aesculin are fermentable sugars; lithium chloride and other antibiotics can inhibit Gram negative bacteria and most Gram positive bacteria.
