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)過嚴(yán)格篩選過程后仔細(xì)挑選的單克隆抗體來實(shí)現(xiàn)：

1、分析耐食物加工的主要過敏原

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

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: wheat, rice, corn, buckwheat, Quinoa, white beans, kidney beans, pinto beans, lima beans, green peas, chick peas, lentils, soy bean flour, soy milk, peanuts, tree nuts, sesame seeds, sunflower seeds, poppy seeds, pumpkin seeds, mustard seed, celery flour, chicken meat, turkey meat.

在濃度高達(dá)100,000 ppm時(shí)，對(duì)一份大型分析樣品和基質(zhì)中沒有觀察到交叉反應(yīng)，包括：小麥，水稻，玉米，蕎麥，藜麥，白豆，蕓豆，斑豆，利馬豆，荷蘭豆，嘴豆，扁豆，大豆粉，豆奶，花生，樹堅(jiān)果，芝麻籽，葵花籽，罌粟籽，南瓜籽，芥菜籽，芹菜粉，雞肉，火雞肉。

RECOVERY 回收

Recovery of spiked whole egg powder samples at various concentrations was efficient (>90%) when the following food matrices were assayed:? flours (wheat, rice, corn), salad dressing, wine, ice cream

當(dāng)分析以下食物基質(zhì)時(shí)，不同濃度全蛋粉樣品的加標(biāo)回收率很高（>90%）：面粉（小麥，水稻，玉米），沙拉醬，葡萄酒，冰激凌
