8-Aminopyrene-1,3,6-trisulfonic acid (APTS) is an anionic fluorescent dye with excitation/emission spectra of 425/503 nm, respectively. It forms a ground state complex with viologen-type quenchers, inducing a red-shift in the absorbance spectrum from 425 to 464 nm. APTS is pH insensitive, with the emission maximum remaining constant over the pH range of 4-10. It can be used in solution or immobilized through attachment of an aldehyde functionalized monomer by reductive amination without significantly changing fluorescence intensity. APTS has been used as a reporter for glucose sensing and for the detection of other saccharides.

Profiling of N-linked glycans from 100 cells by capillary electrophoresis with large-volume dual preconcentration by isotachophoresis and stacking
J Chromatogr A 2018 Aug 31;1565:138-144.PMID:29945790DOI:10.1016/j.chroma.2018.06.034
Glycan structure is changed in response with pathogenesis like cancer. Profiling of glycans from limited number of pathogenetic cells in an early-stage tissue is essential for discovering effective drugs. For analyzing tiny biological samples, we developed sensitive, high-resolution, and salt-tolerant method for analyzing trace level of N-linked glycans by coupling capillary electrophoresis (CE), laser-induced fluorescence (LIF) detection, and a new online sample preconcentration (OSP) method named "large-volume dual preconcentration by isotachophoresis and stacking (LDIS)", which is composed of two OSP methods, large-volume sample stacking (LVSS) and transient isotachophoresis (tITP). A typical LDIS-CE-LIF protocol was simple: a short-plug of leading electrolyte (LE) and large-volume sample solution were introduced to a capillary, followed by application of constant voltage. In the analysis of glucose ladder labeled with 8-Aminopyrene-1,3,6-trisulfonic Acid with 10 mM sodium chloride as LE, up to 2300-fold sensitivity increase was achieved with higher resolution than those in normal CE. By applying pressure assist during preconcentration, both viscous gel electrolyte and salty matrix of up to 10 mM NaCl were acceptable. Finally, N-glycans from approximately 100 cells (HeLa, MCF7, and HepG2) were analyzed as the model of localized tumor cells. From 30 to 40 glycans were successfully detected with almost same profile of large-scale sample. N-glycan structure could be predicted by searching glucose-unit value via Glycobase database, indicating that HepG2 expressed more sialylated glycans and MCF-7 expressed less glycans respectively, comparing with HeLa cells. It suggests the potential of LDIS-CE-LIF for discovery of disease-specific N-linked glycans in microscale environment.
