Structures of POSs detected in wild-type and Engase^−/− MEFs

^aGlycan ID was based on Fig. 3A.

^bElution positions of dephosphorylated, PA-labeled POSs were expressed as glucose units (GU) in dual-gradient reversed-phase HPLC (25).

^cGlycan structures were deduced by dual-gradient reversed-phase HPLC using authentic glycan standards (25).
