Biotium’s goat anti-human IgG, Fc gamma specific antibody is labeled with CF®647 dye. CF® dyes are Biotium’s line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Far-red fluorescent CF®647 dye has excitation/emission at 650/665 nm. The antibody reacts specifically with the human IgG heavy chains and not with light chains or F(ab’)2 fragment of human immunoglobulins. To minimize cross-reactivity, it has been adsorbed against bovine, horse, mouse and rabbit serum IgG prior to conjugation.
