With the ReadyProbes Avidin/Biotin Blocking Solution (1X), why is there a step to add biotin to the sample?
The first step is to bind all endogenous biotinylated entities with an unlabeled avidin. The free D-biotin is then added to bind to all biotin binding sites on this added avidin. The free biotin will be washed away before any other labels are added and all biotin binding sites will be occupied on the unlabeled avidin.
