| 应用 |
Avidin egg white was used in an assay using functionalized xenon as a biosensor to detect biotin-avidin binding. Egg white was used at 80 nmol. |
| 产品介绍 |
Avidin is homotetrameric protein (68kDa) that is obtained from egg whites. This egg protein binds strongly to biotin. Thus, avidin-biotin association has been utilized in immunoassays to detect the localization of antigens in tissues. The use of avidin-biotin immunoassay enhances the sensitivity of the technique and facilitates the detection of antigens in low quantities. |

| 生化机理 |
Avidin forms an extremely strong complex with d-biotin (Kd ~ 10-15). This activity has made both avidin and biotin extremely useful labels in immunochemical methods of detection and quantitation. |
