This product is prepared by labeling highly cross-adsorbed goat anti-mouse IgG (H+L) with CF®505 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. CF®505 dye has excitation/emission at 505/519 nm. To minimize crossreactivity, the antibody has been adsorbed against bovine, chicken, goat, guinea pig, hamster, horse, human, rabbit, rat and sheep serum. Single label antibodies have an average of one dye molecule per antibody molecule, which is reported to be optimal for super-resolution imaging by STORM.
