THE MONOTRACE ADVANTAGE（優(yōu)勢(shì)）

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(kāi)發(fā)了第一條完全以單克隆抗體為基礎(chǔ)的檢測(cè)試劑盒產(chǎn)品（MonoTrace ELISAs），檢測(cè)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(zhǔn)確定的經(jīng)過(guò)嚴(yán)格篩選過(guò)程后仔細(xì)挑選的單克隆抗體來(lái)實(shí)現(xiàn)：

1、分析耐食物加工的主要過(guò)敏原

2、特異性識(shí)別目標(biāo)成分，從而消除交叉反應(yīng)，以及減少“假陽(yáng)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(jì)）的檢測(cè)中表現(xiàn)優(yōu)異

*=參數(shù)的計(jì)算根據(jù)10次代表性的數(shù)據(jù)得出，然而，使用者應(yīng)當(dāng)查閱附隨的分析證書(shū)中的具體批次數(shù)值。

CROSS-REACTIVITY 交叉反應(yīng)

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

在濃度高達(dá)100,000 ppm時(shí)，對(duì)一份大型分析樣品中沒(méi)有觀察到交叉反應(yīng)，包括：核桃、榛子、胡桃、花生、開(kāi)心果、腰果、澳洲堅(jiān)果、巴西堅(jiān)果、松子、芝麻。

RECOVERY 回收

Recovery of spiked soy samples at various concentrations was efficient (>79%) when the following food matrices were assayed: chocolate, cereals, breads, cake

當(dāng)分析以下食物基質(zhì)時(shí)，不同濃度大豆樣品的加標(biāo)回收率很高（>79%）：巧克力，谷類(lèi)食品，面包，蛋糕。
