Solvent resistant heat sealing foil which is peelable. This seal is suitable for low and room temperature compound storage.
The Norgen UltraRanger 1 kb DNA Ladder is prepared to ensure quality and batch-to-batch consistency. Our UltraRanger contains fifteen discrete fragments ranging from 300 bp to 24000 bp with higher intensity reference bands at 5000 bp and 10000 bp. This ladder is ideal for sizing digested DNA of high molecular weight.

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.
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
