APTS Labeled

APTS labeled glycans (9-Aminopyrene-1,4,6-trisulfonic acid) are commonly used as standards for the analysis of glycoproteins by cappilary electrophoresis (CE). The fluorescent APTS molecule confers a strong negative charge to the APTS labeled glycans resulting in rapid separation via capillary electrophoresis.

APTS Label Mass: 523.38981
Fluorescence: excitation = 428 nm, emission = 500 nm.

Molecular formula: C(16)H(8)NNa(3)O(9)S(3)
CAS name/number: 1,3,6-Pyrenetrisulfonic acid, 8-amino-, trisodium salt 196504-57-1
