Ochratoxin B

Description:

Ochratoxin B is a mycotoxin produced by certain species of fungi, particularly Aspergillus and Penicillium. It is a secondary metabolite that is structurally related to ochratoxin A, differing primarily by the absence of a phenylalanine moiety. This compound is characterized by its stability under various environmental conditions, making it a concern in food safety and public health. Ochratoxin B exhibits nephrotoxic, hepatotoxic, and immunosuppressive properties, posing risks to both human and animal health upon exposure. It is commonly found in a variety of agricultural products, including cereals, coffee, and dried fruits, often as a result of fungal contamination during storage. The compound is soluble in organic solvents but has limited solubility in water. Regulatory agencies monitor ochratoxin levels in food products due to its potential carcinogenic effects and its ability to accumulate in the kidneys. Proper storage and handling of susceptible food items are essential to minimize the risk of ochratoxin B contamination.

Ochratoxin B

CAS: 4825-86-9

Ochratoxin B is a mycotoxin that belongs to the group of toxic substances produced by fungi. It is found in animal feed and can contaminate food and water. Ochratoxin B has been shown to be genotoxic, inducing DNA damage in human serum, ochratoxin, tubule cells, and liver cells. It also inhibits the activity of complex enzymes such as DNA gyrase and topoisomerase II. The LC-MS/MS method for detecting ochratoxin B was developed based on its ability to react with an optical sensor that changes color when it binds to the substrate molecule. The hybridoma cell line was used to detect monoclonal antibodies against Ochratoxin B using a sample preparation technique with a detection sensitivity of 0.01 ng/mL.
