Fig. 2. HPLC separation and identification of various fluorophore-labelled CGds. (A) HPLC chromatogram of various labelled CGds, including cholesterol, CG, CAGs, CPGs and lyso-CPGs. Compounds were detected by fluorescence (λex = 428, λem = 528 nm). (B) Molecular structure and MS analysis of CPG(14 : 0/19c : 0). The parent ion was identified by ESI-MS and the fragmented ions by ESI-MS/MS. The corresponding structures and molecular weights are indicated by dashed arrows and numbers.
