Avidin from egg white, CAS No.1405-69-2

CAS: 1405-69-2 Cat. No.: A103033 Número EC: 215-783-6

GRADE & PURITY ≥98%, lyophilized powder,10-15 units/mg protein (E1%/280)

Descripción general

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.
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.
