Description

Attogene’ s Cylindrospermopsin Lateral Flow Kit can be used to detect Cylindrospermopsin in source water samples.

Format: Rapid-Water – Run Time: 30 Minutes, enough to run two samples at 10 and 100 fold dilutions and two negative controls.

Cylindrospermopsin (CYN) is a potent cyanotoxin synthesized by select species of cyanobacteria, prominently including Cylindrospermopsin raciborskii. It belongs to the tricyclic alkaloid class, exhibiting a molecular weight of approximately 415 Da. Structurally, cylindrospermopsin features an uracil ring fused with a hydantoin moiety, alongside a guanidino group, attributes that render it highly soluble and polar in aqueous environments.

Cylindrospermopsin is notorious for its profound toxicity towards aquatic organisms and its potential threat to human health through exposure via contaminated water and food sources. Consequently, rigorous monitoring protocols are essential in regions prone to cyanobacterial blooms, where cylindrospermopsin can accumulate in freshwater reservoirs and other aquatic habitats. In recognition of these risks, regulatory bodies such as the United States Environmental Protection Agency (EPA) have implemented an action level guideline. As of 2019, EPA 10-day drinking water health advisory for cylindrospermopsin recommended a threshold of 0.7 parts per billion (ppb), or 700 parts per trillion (ppt) for children under the age of six, and 3 parts per billion, 3000 parts per trillion for anyone older, to effectively manage cylindrospermopsin levels. This precautionary measure aims to uphold both environmental sustainability and public health integrity by minimizing exposure risks.  The EPA has also drafted a human health recreational water quality criterion to protect human health at 8,000ppt.

EPA 10-Day drinking water Health Advisories for Cylindrospermopsin: 

Do not Drink – 0.7 μg/L for bottle fed infants and preschool children, pregnant and nursing woman, elderly immunocompromised and liver conditions

Do not Drink – 3.0 μg/L for school age children to adults

Do Not Use – 20 μg/L

EPA Draft Human Health Recreational Ambient Water Quality Criteria to protect human health: 8 μg/L

Overview

• Ready-to-use
• Quantitative
• Highly Stable
• Precise
• Eight discrete fragments from 50 bp to 2000 bp
• Higher intensity reference band at 500 bp

The FastRunner DNA Ladder is prepared to ensure quality and batch-to-batch consistency. This Ladder contains eight discrete fragments ranging from 50 bp to 2000 bp with a higher intensity reference band at 500 bp. This Ladder is ideal for quick sizing of PCR products and restriction digests.

Contents
1mL of premixed DNA ladder (0.5µg/10µL) in loading buffer (10mM EDTA, 10% glycerol, 0.015% bromophenol blue, and 0.17% SDS).

FastRunner DNA Ladder (Cat# 12800) – 100 loads

Ladder Properties:
• Eight discrete bands, ranging from 50 bp to 2000 bp
• Higher intensity band at 500 bp for easy reference

Fragment	Size (bp)	Mass (ng)
1	2000	104
2	1500	88
3	1000	68
4	750	59
5	500	93
6	300	28
7	150	35
8	50	25

Recommended Use:
Mix thoroughly. For best results, load 10µL of DNA ladder per well. For precise mass determination with a densitometer, stain gel after electrophoresis using 0.5µg/mL ethidium bromide for 30-40 minutes. The table above shows the size and mass for each band based on 10µL ladder per well.

Storage: 
Stable at room temperature. For longer term storage, -20°C is recommended.

This ladder was standardized using 10µL of DNA per lane on a 0.8 cm thick, 13 x 15 cm, 1.0% agarose gel run in TAE buffer.

Overview

• Robust Lysis Solution processes even the most challenging plant species such as pine needle and grape 
• No phenol extractions
• DNA and all sizes of RNA are recovered, including microRNA
• High quality DNA and RNA are purified simultaneously using the same spin column
• No need to split the lysate​
• Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix

This kit provides for rapid spin column isolation and purification of total RNA and genomic DNA simultaneously from a single plant sample without splitting the lysate. Norgen’s plant lysis solution is highly robust and effective over a wide range of plants including challenging samples.  The total RNA and genomic DNA are both column purified in under 30 minutes.   Since RNA and DNA are isolated without splitting the lysate, variability and inconsistent results are reduced.​​ All sizes of RNA including microRNA are recovered without the need for phenol.  Optional on-column DNase and RNase treatments provide flexibility to isolate DNA-free RNA or RNA-free DNA respectively.  Isolated nucleic acids are of a high quality and yield, and are ready for downstream use including PCR, qPCR, RT-PCR, qRT-PCR, sequencing and more. 

Background

It is often necessary to isolate total RNA and genomic DNA from a single plant sample, such as for studies of gene expression, mutant or transgenic plant characterization, and host plant-pathogen characterization. This is of great benefit when isolating RNA and DNA from precious, difficult to obtain or very small samples. Furthermore, gene expression analysis will be more reliable since the RNA and DNA are derived from the same sample, therefore eliminating inconsistent results.
