    FAM amine, 6-isomer

    		Fluorescent Dye
    FAM amine, 6-isomer is a fluorescein derivative with an amine group and contains an isomer of the fluorophore. Can be used to modify biomolecules through enzymatic transamination. Its fatty amine groups can also react with electrophiles such as activated esters. The amine can also be conjugated to carbonyl compounds (aldehydes and ketones) by reductive amination.

  • HY-172268
    R6G phosphoramidite, 6-isomer

    		Fluorescent Dye Others
    R6G phosphoramidite for oligonucleotide synthesis, pure 6-isomer. R6G (rhodamine 6G) is a xanthene dye of the rhodamine family with high fluorescence quantum yield and high molar extinction coefficient. Relative to those of fluorescein, the absorption (518 nm) and emission (542 nm) maxima of 6-R6G are shifted into the long-wave region.

  • HY-172728
    Difluorocarboxyfluorescein NHS Ester, 6-isomer

    		Fluorescent Dye Others
    Difluorocarboxyfluorescein NHS Ester, 6-isomer is an amine-reactive fluorinated analog of fluorescein that overcomes some of the key limitations of fluorescein, including greater photostability and a lower pKa (pKa ~ 4.7 versus 6.4 for fluorescein), making its fluorescence essentially pH insensitive in the physiological pH range. Although the mixed isomers of Difluorocarboxyfluorescein NHS Ester, is a preferred, routinely used fluorescent dye for labeling proteins, peptides and nucleotides, purification of peptide and nucleotides labeled with 5(6) isomers might be troublesome due to significant signal broadening in HPLC purification. Peptides and nucleotides labeled with a single isomer usually give better resolution in HPLC purification that is often required in the conjugation processes.
