Fumonisin ELISA Kit

Full Name: Fumonisin ELISA Kit
Sample Type: Cereal, Beer/Gyle
Sensitivity: 0.015 ppm

BACKGROUND

Fumonisin belong to a group of mycotoxins which are derived from Fusarium, Liseola section (a common grain mold). There are usually more specifically referred to as Fumonisin-B1, B2 or B3. These toxins are extreme stability to high temperatures (reaching up to 100°C) and they can also remain active within contaminated food for many years. One of the more destructive aspects is that these toxins make the food easier to digest. The World Health Organization has included fumonisin in its list of food toxins which are known to cause cancer. Symptoms include diarrhea, fever and neurological symptoms like headaches and seizures. The worst case is when these symptoms occur in children which can lead to death due to acute kidney failure.

Fumonisin can be found in many different types of grains including oats and maize. In human patients there is evidence to indicate the appearance of esophagus cancer which has been linked to exposition to fumonisin-B1 and when ingested by animals, this can result in hepatotoxicity, lung edema and neurotoxicity (mainly identified in pigs and horses).

INTENDED USE

Fumonisin ELISA kit is intended for detecting rapid quantitative amounts of fumonisin present in beer/gyle or cereals. This assay has a minimum analytical sensitivity limit of 0.015 ppm.

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.

  • Microtiter Plate: Coated with antibody-binding protein.
  • Fumonisin B1 Standards 1-6: Concentration 0-5 ppm.
  • Conjugate (Fumonisin-Peroxidase).
  • Substrate Solution (TMB).
  • Stop Solution.
  • Sample Diluent.
  • Washing Solution (PBS + Tween 20)(10x Concentrate).
  • Instruction Manual.

SENSITIVITY

The minimum detection sensitivity level of fumonisin using current fumonisin ELISA kit was 0.015 ppm. The standard range for this assay is 0.05 – 5.0 ppm.

ASSAY CHARACTERISTICS

– Sensitivity: Limit of detection, LOD (0.015ppm), Limit of quantification, LOQ (0.05ppm)
– Recovery: Corn flour (105%), Beer (105%), Rice flour (94%), Wheat flour (92%), Oats flour (89%).
– Linearity: 86 – 100%
– Intra-Assay Precision: 3 – 4%
– Inter-Assay Precision: 6 – 8%
– Cross Reactivity: Relative to fumonisin B1 (= 100 %): Fumonisin B2 (62%).

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
