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.
