Aflatoxin is toxic and carcinogenic substance, having four principle types of aflatoxin in grain and nuts: B1, B2, G1 and G2. The aflatoxin can be easy found on the commodities, such as, grain, corn, peanuts, cottonseed, milo, and the majority of tree nuts, when cows consume the grain or feeds that containing aflatoxin, they create a metabolite that is found in their milk, mainly is alfatoxin M1, sometime will create aflatoxin M2. http://www.ballyabio.com BALLYA's Aflatoxin M1 Testis special designed for detecting the aflatoxin M1 residues in raw commingled cow milk. Because the molecular structure of those types of aflatoxin is extremelly high similar, they will make a cross-interaction each other, so, our Aflatoxin M1 Test also can detect those types if residues in milk. The detecting levels from 50ppt to 500ppt, correspond with EUROPEAN MRL requirement. It's very significant to detect the aflatoxin residues in milk to avoid any carcinogenic substance. http://www.ballyabio.com Beta-Lactam Testhttp://www.ballyabio.comBT Sensor TestBeta-Lactam+Tetracyclines Combo TestTetracycline TestAflatoxin TestSulfonamide TestFluoroquinolones TestAlkaline Phosphatase TestNeomycin TestGentamicin Test
