B ZERO AFLA B1 48 det. format 96 det. format MA221 MA220 48 det. format 96 det. format ELISA tools for the quantitative detection of aflatoxin B1 in cereals, feed, nuts, spices www.tecnalab.com MA222 MA224

PERFORMANCES  Quickness  High sensitivity, in compliance with worldwide requirements for food and feedstuffs  High accuracy  High reproducibility  Cost-effectivness without forgoing robustness, accuracy and precision  Development of an ELISA test kit format suitable for those implementing a few samples per session with no necessity of installing a lateral flow working station (no dedicated reader) Ease of use  ECONOMY www.tecnalab.com

B ZERO AFLA B1 • 15 minutes assays for the quantitative detection of aflatoxin B1 in cereals, high moisture maize, silage, mash, feed, nuts, dried fruits, DDGS, cottonseeds • Detection limit: 1 ppb aflatoxin B1 • Specificity of the assays: •Aflatoxin B1 100% •Aflatoxin B2 5% •Aflatoxin G1 19% •Aflatoxin G2 < 1% • www.tecnalab.com Sample preparation: grinding, extraction in methanol-water, filtration (EasyPur purification for cottonseeds) For silage and mash pH adjustment of the methanol extracts is advisable.
