structure
ATTO 635
Naphtho[2,3-g]quinolinium, 1-(3-carboxypropyl)-9-(dimethylamino)-2,11-dihydro-2,2,4,11,11-pentamethyl-, perchlorate
862699-22-7
C28H35ClN2O6
531.05g / Mol
Carboxylic acid; also available as NHS-Ester, maleimide and coupled to biotin. High thermal and photostability, only little triplet formation. Dye is moderately hydrophilic. NHS-ester and maleimide show excellent solubility in polar solvents like DMF, DMSO or acetonitrile. Very stable under physiological pH-values and in buffers up to pH 8.5; degrades at higher pH
