THE MONOTRACE ADVANTAGE（優(yōu)勢）

BioFront Technologies has developed the first comprehensive line of monoclonal antibody-based ELISA assay kits (MonoTrace ELISAs) for the detection of allergen protein contamination in a variety of food samples. MonoTrace ELISAs incorporate the use of a precisely defined set of handpicked monoclonal antibodies selected after a rigorous screening process for their ability to:

1、Target a major allergen resistant to food processing effects

2、Recognize a specific target, thereby eliminating cross-reactivity and reducing the possibility?

? of‘false positive’results

3、Perform well in a wide variety of food products with negligible food matrix interference

BioFront Technologies開發(fā)了第一條完全以單克隆抗體為基礎的檢測試劑盒產(chǎn)品（MonoTrace ELISAs），檢測各種食物基質(zhì)中的致敏蛋白污染。MonoTrace ELISAs綜合使用一系列精準確定的經(jīng)過嚴格篩選過程后仔細挑選的單克隆抗體來實現(xiàn)：

1、分析耐食物加工的主要過敏原

2、特異性識別目標成分，從而消除交叉反應，以及減少“假陽性”結(jié)果的可能性

3、在各種食品（食品基質(zhì)干擾可以忽略不計）的檢測中表現(xiàn)優(yōu)異

CROSS-REACTIVITY 交叉反應

At concentrations as high as 100,000 ppm, no cross-reactivity was observed in a large panel of assayed samples, including: almond, cashew, hazelnut, pecan, peanut, pistachio, pecan, macadamia nut, Brazil nut, and pine nut.

在濃度高達100,000 ppm時，對一份大型分析樣品中沒有觀察到交叉反應，包括：杏仁、腰果、榛子、胡桃、花生、開心果、澳洲堅果、巴西堅果、松子。

RECOVERY 回收

Recovery of spiked walnut samples at various concentrations was efficient (>80%) when the following food matrices were assayed: chocolate, cereals, ice cream, cakes, cookies.

當分析以下食物基質(zhì)時，不同濃度核桃樣品的加標回收率很高（>80%）：巧克力，谷類食品，冰激凌，蛋糕，曲奇。
