SABC (StreptAvidin-Biotin Complex) is specially designed for displaying the distribution of antigens in tissues and cells in immunochemistry and other immunodetection analyses. This kit has high sensitivity because each complex it generates has a large number of Cy3 and streptavidin molecules. Compared to the traditional immunodetection using free Cy3 dyes, the SABC-Cy3 system greatly enhances the sensitivity and suppresses the background. Cy3 is activated at 554nm, fluorescing at 568~574nm with bright red.
