Notes: Sterigmatocystin-13C18 is intended for use as an internal standard for the quantification of sterigmatocystin (Item No. 11441) by GC- or LC-MS. Sterigmatocystin is a mycotoxin that has been found in Aspergillus.{31928,31929} It is lethal to rats (LD50 = 60 mg/kg) and chick embryos (LD50s = 5-7 µg/embryo).{31929} Sterigmatocystin (100 and 1,000 ppb in drinking water) induces gastritis, as well as intestinal polyp formation and metaplasia in aged Mongolian gerbils.{31928} It induces formation of lung and liver adenomas and malignant lymphomas in newborn mice.{60099}
