6-TAMRA CPG (glycerol) is controlled pore glass (CPG) with the fluorescent dye 6-carboxytetramethylrhodamine (6-TAMRA) covalently attached via a glycerol linker. This support is designed for automated solid-phase oligonucleotide synthesis using the phosphoramidite method, allowing the introduction of a fluorescent label at the 3′-end without additional post-synthetic labeling steps.

The 1000 Å pore size is optimal for synthesizing long sequences — up to 100 nucleotides. 6-TAMRA is a orange-red fluorescent dye with absorption and emission maxima at 541 nm and 567 nm, respectively, and is widely used in molecular diagnostics. TAMRA-labeled oligonucleotides obtained with this reagent are employed in methods such as real-time PCR, fluorescence in situ hybridization (FISH), FRET, and surface-enhanced Raman spectroscopy (SERS).
