Aflatoxin G2

(7241-98-7)
Aflatoxin G2 is the minor analogue of the green fluorescent family of bisfuranocoumarin mycotoxins produced by Aspergillus flavus and related species. Aflatoxins are one of the most potent mycotoxins known but are in fact "pre-toxins", requiring metabolic activation to the toxic principle. Aflatoxins are found widely in nature in trace amounts, particularly in grains and nuts. The toxicity of these metabolites was first recognised in the 1950s and their structures elucidated in 1963. Aflatoxins

In the analysis work, it is often necessary to use a compound of good quality and accurate content, which is used as a comparison for detection control, or used to calibrate the instrument. This compound is called a standard. Or standard. The standard product refers to the standard substance used to determine the potency of biological products. The production department must provide the standard product expressed in units (μ) of its potency when it is approved as a quality standard for biological products. According to the application, the standard products for inspection can be divided into biological standard products for biological verification of biological products, endocrine drugs, antibiotics and so on.
