Description

Attogene’s Microcystin Test Kit (Rapid – Recreational Water) can be used to detect microcystins in liquid samples; highly sensitive, rapid, robust screening kit for algae toxins 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 different numeric thresholds for microcytin-LR concentrations in recreational waters has been developed. This is guidance that allows states to take various actions—such as posting information about harmful algal blooms (HABs), issuing a recreational public health advisory, or temporarily closing recreational waters through a no contact advisory—depending on the severity of the bloom event.

Microcystin-LR

Informational sign postings about HABs at recreational waters: < 6 μg/L
Recreational public health advisory: 6 μg/L
Elevated recreational public health advisory (e.g. no contact): 20 μg/L

Description

Attogene’s Lead Rapid Lab Lateral Flow Kit can be used for the screening of Lead in water and food samples at greater than or equal to 10 ppb in a laboratory setting.  Unlike the field-based kit, the lab kit is intended for a more technical end user who will be evaluating samples in a laboratory setting.

Lead contamination is a serious worldwide environmental problem. As it is difficult to detoxify by chemical or biological methods, gradual Lead ion accumulation in the nervous and cardiovascular systems of the human body can subsequently cause serious diseases.   Long-term health consequences of drinking Lead-contaminated food and water include brain, heart, kidney, lungs  and immune system problems for adults, and the physical and mental development delays in infants and children.  Attogene’s Lead Lateral Flow test gives results conforming of 10ppb or greater in 5-15 minutes.

This is a revolutionary product designed to make Lead testing in easy and affordable.  This fast screening test kit contains 10 tests with everything needed for accurate results of unsafe lead levels. With reliable results in only 10 minutes, this test kit clearly gives results confirming Lead in water and conforming to the EPA guideline of 15 ppb (µg/L).

Sample Collection:

1. Take a first-draw sample

Immediately after opening a faucet or valve, collect a 250 mL sample. This sample should be from each tap used for consumption.

2. Take a flush sample

If first-draw sample results show elevated lead levels of 5 ppb or higher, collect a flush sample. To do this, ensure water has not been used for between 8 to 18 hours, then collect the sample at 30 seconds.

3. Take sequential samples

If you want to test a lead service line, collect 8 to 10 sequential samples, depending on how far the line is from the tap.

Standards and Regulations and recommendations for Lead

• EPA: Drinking Water: 15ppb
• FDA: Juice: 50ppb
• EPA: Residential Soil: 400 ppm (play areas), 1200 ppm (non-play areas)
• CPSC: Paint: 90ppm
• FDA: Bottled drinking water: 5ppb

High Blood lead levels (i.e., greater than 700ppb) can cause serious health effects, including seizure, coma, and death.  Blood levels as low as 100ppb have been associated with adverse effects on cognitive development, growth, and behavior among children aged 1-5 years.

Introduction

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.
