General description

赭曲霉毒素 A是一种霉菌毒素，天然存在的次级代谢产物，由 曲霉菌 和 青霉菌等丝状真菌产生。它已被国际癌症研究机构归类为2B类物质，可能对人类具有致癌性

Application

CRM还可被用于以下实验：
  • 使用悬浮固化分散液液微萃取技术（DLLME-SFO）样品处理和超高效液相色谱-正电电喷雾电离-串联质谱法（UHPLC-(+-ESI)-MS/MS)鉴定和测定不同类型商业咖啡样品中的赭曲霉毒素A
  • 基于盐析辅助液-液萃取(SALLE)和超高效液相色谱-串联质 (UHPLC-MS/MS)的选择性方法测定啤酒样品中的赭曲霉毒素 A
  • 使用在线固相萃取(SPE)结合高效液相色谱-荧光检测(HPLC-FD)法同时测定托卡伊酒样品中赭曲霉毒素A和赭曲霉毒素B
  • 开发一种在线SPE-HPLC方法测定葡萄酒样品中的赭曲霉毒素 A
  • 使用基于功能化石墨烯（f-石墨烯）掺杂壳聚糖的适配体通过差分脉冲伏安法对葡萄汁样品中的赭曲霉毒素 A进行电化学测定

The paper reported a reliable analytical method for simultaneous determination of ochratoxin A (OTA) and ochratoxin B (OTB) in traditional Chinese medicines (TCMs) by ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). The development of the method and investigations on the matrix

The ochratoxin A (OTA) polyketide synthase otapks gene has been cloned from Penicillium verrucosum. A P. verrucosum mutant in which the otapksPV gene has been interrupted cannot synthesize ochratoxin A. The protein is most similar to the citrinin polyketide synthase

By taking advantage of the intrinsic fluorescence of ochratoxin A (OTA), we present a fluorescence anisotropy approach for rapid analysis of the interactions between OTA and aptamers. The specific binding of OTA with a 36-mer aptamer can induce increased fluorescence
