6-CR110, SE [6-Carboxyrhodamine 110, succinimidyl ester]*Single isomer* is a Fluorescein for peptide and oligonucleotide labeling. Compared to fluorescein labeling reagents such as FITC and FAM, CR110 reagents give more photostable and pH-independent bioconjugates that have the absorption maximum around the preferred 488 nm excitation wavelength. They are photostable alternative reagents superior to FITC and FAM.
JF526–Pepstatin A TFA, a fluorescent dye, is utilized for lysosomal staining in live cells. It exhibits an excitation maximum at 530 nm and an emission maximum at 549 nm [1].
