This product is prepared by labeling highly cross-adsorbed goat anti-mouse IgG (H+L) with CF®543 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. Orange fluorescent CF®543 dye has excitation/emission at 541/560 nm. To minimize crossreactivity, the antibody has been adsorbed against bovine, chicken, goat, guinea pig, hamster, horse, human, rabbit, rat and sheep serum.
