5 (6) -CR110, SE [5- (and 6) -Carboxyrhodamine 110, succinimidyl ester] *Mixed isomers*

5 (6) -CR110, SE is a mixed-isomer succinimidyl ester dye for labeling peptides and oligonucleotides. It offers superior photostability and pH-independent fluorescence compared to FITC/FAM, with an absorption peak near 488 nm. This makes it a robust choice for fluorescence imaging and detection in both in vitro assays and in vivo research applications.
