5(6)-ROX, SE

5-(and-6)-Carboxy-X-rhodamine, succinimidyl ester; Mixed isomers

5(6)-ROX, SE is the succinimidyl esters of 5(6)-ROX. It is the mixed isomers of ROX dye. The ratio of 6-isomer/5-isomer is in the range 3/1 to 6/1. This product is the primary labeling reagents for preparing various ROX-based bioconjugates. Compared to other rhodamines, ROX is very unstable. Cautions must be exercised to prevent the deterioration during storage.
