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.
No cold shipping required. Our unique, oasig Lyophilised qPCR Master Mix in a 150 reaction pack. Perfect to accompany any genesig kit for a DNA target.
Primerdesign real-time PCR reagents are manufactured to the highest standards within our ISO9001:2008 and ISO13485:2012 certified quality management laboratory environment.
Usages: For differentiating enteric bacteria based on urease activity by adding 40% sterile urea solution.
Principle: Peptone provides the carbon and nitrogen; maintain a balanced osmotic sodium chloride; potassium dihydrogen phosphate is buffers; decomposing bacteria urease urea medium, produce large amounts of ammonia, agar as medium coagulant.
Formulation (per liter): Peptone 1g Sodium chloride 5g Glucose 1g Ppotassium dihydrogen phosphate 2g Phenol red 0.012g Agar 12g Final pH7.2 ± 0.2
How to use: 1.Suspend 21g in 1L of distilled or deionized water. Heat with frequent agitation and boil to completely dissolve the powder. Distribute into flasks. Autoclave at 121 for 15 minutes. cooling to 50-55 and adding 40% urea solution. 2.Diluted and treated samples.
Storage: Store in a dark, cool and dry place, tighten the cap immediately after use. Storage period of three years.
Free-circulating nucleic acids, such as tumor-specific extracellular nucleic acid fragments and mRNAs in the blood or fetal nucleic acids in maternal blood, are present in serum or plasma usually as short fragments, <1000bp(Nucleic Acid). The HiPure Circulating Nucleic acid Micro Kit enables efficient purification of these circulating nucleic acids from human plasma, serum, or urine. Samples can be either fresh or frozen (provided that they have not been frozen and thawed more than once). Free-circulating cell-free DNA, RNA or viral nucleic acids are eluted in Nuclease Free Water, ready for use in amplification reactions or storage at -30 to -15°C. Purified nucleic acids are free of proteins, nucleases, and other impurities.

Principle
This product is based onsilica column purification. The sample is lysed and digested with lysate andprotease, DNA is released into the lysate. Transfer to an adsorption plate andfilter column. Nucleic acid is adsorbed on the membrane, while protein is notadsorbed and is removed with filtration. After washing proteins and otherimpurities, Nucleic acid was finally eluted with low-salt buffer.
Advantages
High yield – most optimal process, free DNA (>50bp) can be obtained to the maximum extent
High concentration – low elution volume, ensuring high nucleic acid concentration
High purity – low alcohol binding method, completely removing inhibitor and protein pollution
High recovery – DNA can be recoveredat the level of PG by silica gel column purification

Storage and Stability
Proteinase K, Carrier RNAshould be stored at 2-8°C upon arrival. However, short-term storage (up to 12weeks) at room temperature (15-25°C) does not affect their performance. Theremaining kit components can be stored dry at room temperature (15-25°C) andare stable for at least 18 months under these conditions. The entire kit can bestored at 2-8°C, but in this case buffers should be redissolved before use.Make sure that all buffers are at room temperature when used.
