Detail
Screening of Microcystins in water samples at 0.1 ppb (drinking water)
Attogene’s Microcystin Test Kit (Rapid – Drinking Water) can be used to detect microcystins in water to as low as 0.1ppb; highly sensitive, rapid, robust screening kit for microcystins and nodularins.
The most frequently reported cyanobacterial toxins are the hepatotoxic microcystins (MCs). MCs are peptides with a molecular weight ranging from 900 to 1,100 Da. They consist of seven amino acids of which the two terminal amino acids of the linear peptide are condensed to form a cyclic compound.
A tiered notification system which takes different actions based on thresholds for microcytin-LR concentrations in drinking waters has been developed. This is guidance that allows states to take various actions.
For the rapid screening of microcystins in drinking water samples at or above 0.1 ppb. Samples requiring regulatory action should be confirmed by ELISA, HPLC, or other conventional methods.
To protect consumers from adverse health effects caused by these toxins, the World Health Organization (WHO) has proposed a provisional upper limit for Microcystin-LR of 1.0 ppb (μg/L) in drinking water.
The U.S. Environmental Protection Agency (EPA) has also established guidelines for Microcystins in drinking water:
-For children below school age, 0.3 μg/L (ppb)
-For all other age groups, 1.6 μg/L (ppb)

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
Bind and elute all RNA irrespective of size or GC content, without bias
The purified exosomal RNA is free from any circulating RNA-binding proteins
No phenol extractions, Proteinase K treatment nor carrier RNA required
No time-consuming ultracentrifugation, filtration nor special syringes are required
No precipitation reagents nor overnight incubation required
Concentrate isolated exosomal RNA and 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 urine 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, irrespective of size or GC content, without bias. These kits provide a clear advantage over other available kits since they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the 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.

Storage Conditions and Product Stability All buffers 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 Urine samples stored at -70°C, -20°C or at 4°C will develop some precipitation due to the aggregation of some of the highly abundant proteins in urine. Eliminating these precipitates using centrifugation or filtration may cause the loss of exosomes. Furthermore, these precipitates may affect the quality of the purified nucleic acid. We recommend the use of Norgen’s Urine Preservative when collecting urine samples, which is designed for the preservation of nucleic acids and proteins in fresh urine samples at ambient temperatures. The components of the Urine Preservative allow samples to be stored for over 2 years at room temperature with no detected degradation of urine DNA, RNA or proteins. Norgen’s Urine Preservative is available as a liquid format in Norgen’s Urine Preservative Single Dose Ampules, as well as in a dried format in Norgen’s Urine Collection and Preservation Tubes.

Principle
This product is based on silica Column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while proteinis not adsorbed and is removed with filtration. After washing proteins and other impurities, Nucleic acid was finally eluted with low-salt buffer (10mmTris, pH9.0, 0.5mm EDTA). This product carries 0.1-0.2mm acid glass beads, which can improve the wall-breaking effect of lysozyme resistant bacteria, the success rate and DNA yield through physical bead grinding.
Advantages
Fast – several samples can be extracted in 40 minutes (after digestion)
High purity – purified DNA can be directly used in various downstream applications
Good repeatability – silica technology can obtain ideal results every time
High recovery – DNA can be recovered at the level of PG
Broad spectrum – it can deal with a variety of bacteria, including Gram-positive bacteria that are difficult to disrupt
Sufficient components – this kit has carried lysozyme, protease K, RNase A and glass beads

Storage and Stability
Lysozyme and Proteinase K should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 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.
