Ochratoxin A (OTA) is a toxic metabolite produced by Aspergillus flavus and Penicillium genera. Ochratoxin A has a strong liver and kidney toxicity, and has teratogenic, mutagenic, and carcinogenic.

OTA is the second important and harmful mycotoxin in the family following with Aflatoxin flavus. As the OTA producing fungi exist widely in nature, especially higher yield in cereals and cereals products, coffee, cocoa contaminated with OTA, it has been potential threat for human health and development of animal husbandry.

Immunoaffinity Column for Aflatoxin B1,B2,G1,G2

The immunoaffinity column can selectively adsorb aflatoxins (B1, B2, G1, G2) from the sample solution, thereby purifying the sample. The purified sample solution can then be directly used for HPLC or LC-MS/MS analysis.Affinity columns can be used in combination with HPLC or LC-MS/MS to achieve rapid testing, and to increase signal-noise ratio  and improve the accuracy of the detection method.

Order No.: QC0068,QC0069,QC0131,QC0071Column Capacity:100 ngVolumn: 3mLPackage: 25/50T 

Immunoaffinity Column for 2-in-1 Aflatoxins (B1,B2,G1,G2) and Ochratoxin A

The immunoaffinity column can selectively adsorb aflatoxin (B1, B2, G1, G2) and Ochratoxin A from the sample solution, thereby having a highly targeted purification effect on the sample. The sample  solution that has been purified by passing through the affinity column can be directly used for HPLC analysis or for LC-MS/MS analysis after concentrating with nitrogen gas and resuspended.Order No.: HCM3725B/HCM3750BProduct Properties: AFT B1/B2/G1/G2 300ng, OTA 100ngSpecifications: 3mL,25T/50T
