Application: | Avidin-Peroxidase has been used for detecting anti-5-bromodeoxyuridine (anti-BrdU) binding and OVA-IgG1. |
Application: | To detect Ga1-deficient IgA1 antibodies in mouse serum, ELISA assays were performed using sera which was incubated with biotinylated HAA, which binds IgA1, in 96-well plates. HRP-conjugated avidin was then incubated with the sera for 40 minutes at 37 degrees. |

General description: | 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. |
Physical form: | Lyophilized powder containing citrate buffer. |
Preparation Note: | Labeled with Type VI peroxidase. Coupled by a modification of the method of Sullivan, M.J., et al., FEBS Lett., 95, 311 (1978). |
