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.

The D-Glucose Assay Kit (Megaplex Red) provides a simple robust method for the measurement of D-glucose. This kit utilises a highly sensitive Megaplex Red probe which when coupled to horseradish peroxidase (HRP) and glucose oxidase (GOX) enzymatic reactions, allows for the measurement of D-glucose in a sample. Upon oxidation of the probe by HRP, a coloured product (resorufin) is formed that can be measured in fluorescence mode using excitation between 530-560 nm and emission at ~ 590 nm* or colourimetrically at 570 nm.
*The excitation and emission maxima of Megaplex Red are 570 nm and 585 nm respectively.
Fluorometric/UV method for the determination of D-glucose content in a variety of samples.
Advantages
Simple format
Very competitive price (cost per test)
Ability to run in fluorescence or absorbance mode
User friendly – Detailed protocol provided for the creation of calibration curve and the calculation of concentration in fluorescence mode. Single point standard for quicker and simpler analysis in absorbance mode.
Mega-Calc™ software tool is available from our website for hassle-free raw data processing
Suitable for manual, microplate and auto-analyser formats
All reagents stable for > 2 years

Kit contents
Champion™ Competent Cells
pUC19 Control Plasmid (5 μl, 10-4 μg/μl)
Champion™ Transformation Protocol Card
Shipping condition
Throughout the shipping process, the temperature is maintained under -70°C.
Storage and expiration
Champion™ Competent Cells must be stored between -70°C to -80°C. Subsequent freeze-thaw cycles will reduce transformation efficiency. If high efficiency is required for the experiment, do not use aliquots that have gone through several freeze-thaw cycles. The efficiency of Champion™ Competent Cells lasts for 1 year with proper storage.
