avidin, a glycoprotein in raw egg white that interacts with biotin to make it unavailable to the body. Cooking destroys avidin. A 68-kD tetrameric glycoprotein found in egg white which has a high affinity for biotin, an association used in immunology for the avidin-biotinylated immunoperoxidase method.When eggs are eaten in excess, avidin-biotin avidity may cause biotin deficiency. glycoprotein, obtained from egg whites, that possesses a high affinity for biotin. Labeled avidin is allowed to bind to biotin-tagged antibodies to amplify antigen-antibody reactions that may be difficult to visualize.
Thereâs just one aspect of the show that may be a little off-putting to Marylanders. Though itâs supposedly set in Maryland and all about living on the shores of the Chesapeake Bay, it was filmed thousands of miles away â on Vancouver Island, British Columbia, Canada.
