Frontal affinity chromatography equipped with mass spectrometry (FAC-MS) has been used to screen ligands binding to immobilized target proteins and measure their dissociation constants [1]. Herein, FAC-MS system has been developed and utilized for monitoring protein-carbohydrate interactions, which play significant roles in biological events such as cell-cell interactions, invasions, metastasis, and so on. Complex glycans expressed on porcine endothelial cell are responsible for immune rejections upon pig-to-human xenotransplantation [2]. Except terminal alpha-linked galactose of porcine glycan structures, called alpha-Gal epitope, mediating hyperacute rejection, other carbohydrate moieties, called non-Gal epitopes, could be potential xeno-antigens because alpha-Gal knock-out method could not prevent immune rejection completely. Recently, we found that human CD154 was bound to porcine glycans immobilized on solid support with/without terminal alpha-Gal epitope in vitro. Therefore, we tried to reveal which glycan structures would be specific for human soluble CD154 using FAC-MS. After FAC-MS experiment, various glycan structures were categorized by their relative affinit ies for human souluble CD154.
