一般說明
Sterigmatocystin is classified under the mycotoxin family of compounds. It is usually produced by the fungi of several species of Aspergillus.
應用
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Sterigmatocystin may be used as an analytical reference standard for the determination of the analyte in:
- Grain samples by high-performance liquid chromatography-electrospray positive ionization-tandem mass spectrometry (HPLC-ESI+-MS/MS).
- Beer samples by HPLC in conjunction with UV detection.

Sterigmatocystin (ST), a common environmental contaminant found across the world, is generally recognized as a potential carcinogen, mutagen and teratogen. Our previous epidemiological studies suggested that ST exposure might be a risk factor for esophageal cancer. However, the direct effects

Sterigmatocystin (ST), a mycotoxin commonly found in foodstuff and feedstuff, has been shown to be a carcinogenic mycotoxin in animal models. Many studies showed that the high level of ST contamination in grains might be related to the high incidence
