Each bead is coated with fluorescently labeled antibodies that bind to a particular microbe 每一顆磁珠表面都接有標上螢光劑的抗體,可以結合特定的微生物。
Labeled antibodies that have not docked to the sample tumble about so rapidly in solution that they give off no magnetic signal 帶磁性顆粒的抗體要是沒有與樣本產生結合,會在溶液中快速旋轉,因而無法產生磁性訊號。
The capture of the labeled antibody ? analyte complex for signal generation can be achieved with the antibody immobilized in a defined area of nitrocellulose membrane as mentioned 對產生信號的標記抗體抗原復合物的捕獲,是用抗體固定在已經提到的硝酸纖維素的特定區域內來達到的。
In determining the optimal concentration of each antibody , we have used a strategy in which the capture antibody is first immobilized at a particular density on the predetermined site of membrane , and the labeled antibody is then varied to retain a maximum signal - to - noise ratio 在測定每個抗體的最佳濃度中,我們用到了這樣一個方案:先將捕獲抗體以特定的濃度固定在膜上預留的部位,然后改變標記抗體濃度得到最大的信號噪音比例。
It was proved that the amount of immobilized antibody and the immunoactivity of bound antibodies could be well improved by colloidal au . hrp labeled antibody reacted with antigen , then hrp biocatalyzed dab ( 3 , 3 ’ - diaminobenzidine ) in the presence of h _ 2o _ 2 , resulting in an insoluble product onto the electrode surface , to achieve an obviously decreased frequency 在h _ 2o _ 2存在下,通過標記在抗人igg抗體上的辣根過氧化物酶( hrp )催化底物3 , 3 ’ -聯苯二胺( dab ) ,反應生成不溶性產物沉積到石英晶振的au電極表面,達到質量放大的目的。
