T-2 Toxin ELISA Kit

INTENDED USE

T-2 toxin ELISA kit is intended for measuring rapid quantitative concentrations of T2 toxin (T-2 toxin and T-2 mycotoxins) in food (such as beer, meat, milk and cereal). This assay has a minimum analytical sensitivity limit of 13.0 ppb.

BACKGROUND

T-2 toxin is a trichothecene mycotoxin, a naturally occurring mould formed as a by-product of fusarium (a fungus that is toxic to both animals and humans). The most important species include: F. acuminatum, F. sporotrichioides, F. poae and F. langsethiae. These fungi are present in grains such as oats, wheat and barley.

Both animals and humans can be exposed to T-2 mycotoxins through food and unlike most biological toxins it can absorbed via intact skin. It is also possible to deliver this compound through water, food, aerosols and droplets. Acute toxic dosages have been found to lead to gastroenteritis, necrosis of skin, damage of respiratory passages and bone marrow. T-2 toxins display high level of stability against temperature, this allows detection to be made in bakery products.

T-2 TOXIN ELISA KIT CONTENT

All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

SENSITIVITY

The minimum detection sensitivity level of T2 toxin (such as T-2 mycotoxins) using current T-2 toxin ELISA kit was 13.0 ppb. The standard range for this assay is 17.5 – 1,750.0 ppb.
