Biotiums goat anti-human IgA (alpha chain) is labeled with CF488A dye. CF dyes are Biotiums line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Green fluorescent CF488A dye has excitation/emission at 490/515 nm. It is prepared from antibodies purified by human IgA-affinity chromatography. The antibodies react specifically with IgA heavy chains (alpha chains) and not with immunoglobulin light chains. To minimize cross-reactivity, it has been adsorbed against human IgG prior to conjugation.
