Fluorescent Dyes  >  Reactive Fluorescent Dyes  >>  5(6)-TAMRA-X, SE

Product Name 5(6) - TAMRA - X, SE
6 - (Tetramethylrhodamine - 5 - (and - 6) - carboxamido) hexanoic acid, succinimidyl ester; 5(6) - TAMRA - X, NHS ester
Size 5 mg
Catalog # AS-81127

TAMRA-X contains a seven-atom aminohexanoyl spacer (known as X) between TAMRA fluorophore and the succinimidyl ester. The X spacer separates the fluorophore from the biomolecule to which it is conjugated, potentially reducing the quenching that typically occurs upon conjugation. We recommend this TAMRA-X derivative as the preferred dye for preparing TAMRA-labeled proteins when the fluorescence quenching of the labeling dye by protein is a serious problem.
