一般描述

Certan 样品瓶
赭曲霉素是一种霉菌毒素，由曲霉 和 青霉菌菌属产生。成产赭曲霉素的菌属广泛分布于谷物等食品中。赭曲霉素是异香豆素的衍生物。通过使用适体（体外选择与分子靶标结合的单链寡核苷酸）检测曲霉毒素A的方法已有报道。

应用

有关合适的仪器技术的更多信息，请参阅产品的分析证书。想要获得更多支持，请联系技术服务部。
通过免疫亲和柱净化和高效液相色谱法将曲霉毒素A（OTA）用于对餐酒中OTA的定量测定中。它已在样品纯化方法中被作为分析标准品，通过免疫超滤对谷物中的OTA进行分析。它已被用作分析标准品，研究OTA对在高密度“微团培养”中培养的大鼠胚胎神经细胞的影响。

This work describes the identification of an aptamer that binds with high affinity and specificity to ochratoxin A (OTA), a mycotoxin that occurs in wheat and other foodstuffs, and a quantitative detection method for OTA based on the use of
Iwona Wilk-Zasadna et al.
International journal of molecular sciences, 10(1), 37-49 (2009-04-01)
Embryonic midbrain micromass cultures were exposed for five days to ochratoxin A (OTA) at seven concentrations (ranging from 0.16 to 10 microg/mL). Cell viability was assessed in neutral red uptake test (NRU), and differentiation - by immunoenzymatic determination of structural

Analytical and bioanalytical chemistry, 400(8), 2615-2622 (2011-04-05)
The paper presents a new sample clean-up method based on immuno-ultrafiltration for the analysis of ochratoxin A in cereals. In contrast to immunoaffinity chromatography, in immuno-ultrafiltration, the antibodies are used in non-immobilised form. Ochratoxin A was extracted with ACN/water (60/40

Journal of chromatography. A, 864(1), 89-101 (2000-01-12)
A new and accurate method to quantify ochratoxin A (OA) in table wine has been developed. The method uses commercial immunoaffinity columns for clean-up and high-performance liquid chromatography (HPLC) with fluorescence detection for quantification of the toxin. Wine was diluted
Xia Geng et al.
Analytical and bioanalytical chemistry, 405(8), 2443-2449 (2013-01-31)
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
