| Application: | 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. |
| Application: | Egg white avidin has been used as a cross-linker for biotin-conjugated antibodies. The product has also been used as a blocking agent in ELISA applications. |

| General description: | Avidin protein is a 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. |
| Other Notes: | One unit will bind 1.0 μg of d-biotin. |
