%0 Journal Article %T Development of a Monoclonal Antibody-Based Sandwich ELISA for Peanut Allergen Ara h 1 in Food %A Juan Peng %A Shanshan Song %A Liguang Xu %A Wei Ma %A Liqiang Liu %A Hua Kuang %A Chuanlai Xu %J International Journal of Environmental Research and Public Health %D 2013 %I MDPI AG %R 10.3390/ijerph10072897 %X We have established a highly sensitive sandwich enzyme-linked immunosorbent assay (ELISA) based on two monoclonal antibodies (mAb) to measure the content of the major peanut allergen Ara h 1 in foods. Two mAbs were selected out of 12 murine hybridoma cells secreting Ara h 1-specific antibody. Using mAb 6 as the capture antibody and HRP-labelled mAb 4 as the detection antibody, the limit of detection (LOD) the assay was 0.34 ng/mL. Cross-reaction analysis showed that this method was strongly specific and had no cross-reactions with Ara h 2, pea protein or soy protein. Sample analysis showed that this ELISA was a useful tool to monitor peanut allergens in food products by measuring Ara h 1 content. %K peanut allergen %K Ara h 1 %K monoclonal antibody %K sandwich ELISA %U http://www.mdpi.com/1660-4601/10/7/2897
