n
wherein n is an integer from 2 to 10; m is zero or 1; and Av is the residue of an avidin-type molecule selected from the group comprising native egg-white avidin, recombinant avidin, deglycosylated avidins, bacterial streptavidin, recombinant streptavidin, truncated streptavidin and other derivatives of said avidin-type molecules. These HABAylated avidins are red colored in the quinone configuration and can be used in many applications in the avidin-biotin technology.
