Attogene test uses the property of formaldehyde to react with the Formaldehyde Reaction Powder (FRP) to form a purple-red tetrazine. The formaldehyde concentration is measured by visual comparison of the reaction with the color scale derived from the Color Card.
Formaldehyde is an organic compound with the formula CH2O. It is mainly used in the production of industrial resins but has been found to be used as a preservative, disinfectant and biocide. Because of its toxicity and volatility formaldehyde poses a significant risk to human health. Attogene test uses the property of formaldehyde to react with the Formaldehyde Reaction Powder (FRP) to form a purple-red tetrazine. The formaldehyde concentration is measured by visual comparison of the reaction with the color scale derived from the Color Card.

Overview
Isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias.
Versatile sample input ranges
Isolate all sizes of free-circulating RNA, including microRNA
The purified exosomal RNA is free from any circulating RNA-binding proteins
No phenol extractions, Proteinase K treatment, nor carrier RNA
No time-consuming ultracentrifugation, filtration nor special syringes are required
No precipitation reagents, nor overnight incubation required
Concentrate isolated exosomal RNA and are free-circulating RNA into a flexible elution volume ranging from 50 µL to 100 µL
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
These kits provide a fast, reliable and convenient method to sequentially isolate and concentrate exosomal RNA as well as Free-Circulating RNA from different plasma/serum sample volumes. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. These kits are designed to isolate all sizes of RNA, including microRNA as well as all sizes of the free-circulating protein-bound RNA, including microRNA. These kits provide a clear advantage over other available kits in that they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, these kits allow the user to elute into a flexible elution volume ranging from 50 µL to 100 µL. The RNA isolated from the purified exosomes is free from any protein-bound circulating RNA and is of the highest integrity. Moreover, the free-circulating, protein-bound, RNA is free from any exosomal RNA. The purified RNA can be used in a number of downstream applications including real time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.

*Please check page 5 of the product insert for the average yields and the common RNA quantification methods
Storage Conditions and Product Stability All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment. It is recommended to warm Lysis Buffer A for 20 minutes at 60°C if any salt precipitation is observed.
Important Note This kit is suitable for the purification of exosomes from fresh or frozen serum or plasma prepared from blood collected on either EDTA or Citrate. Plasma samples prepared from blood collected on heparin should not be used as heparin can significantly interfere with many downstream applications such as RT-PCR.
MagPure Stool DNA Kit is specially designed for high throughput DNA extraction from stool samples. It can get high purity microbial DNA from stool samples (≤200mg). This kit is based on magnetic beads purification and unique inhibiting factors adsorption technology, no phenol-chloroform extraction or alcohol precipitation. It can adsorb humic acid and other inhibiting factors in the solution efficiently. DNA can be directly used for downstream applications such as PCR, Viral DNA testing, bacterial DNA testing, etc.

Principle
This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and Lysozyme. DNA is released into the lysate. After adding magnetic particles and binding solution, DNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol to remove salts, and finally DNA was eluted by Elution Buffer.
Advantages
Fast – several samples can be extracted in 60 minutes (after digestion)
High purity – unique adsorbent can completely remove inhibitory factors
High recovery – DNA can be recovered at the level of PG

Storage and Stability
MagPure Particles, RNase A and Proteinase K should be stored at 2-8°C upon arrival. However, short-term storage (up to 24 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions.
