High-performance anion exchange chromatography with pulsed amperometric detection (HPAEC-PAD) and thin-layer chromatography (TLC) chromatograms of CCK-oligosaccharide (produced by L. lactis CCK940) acid hydrolysate. (a) HPAEC-PAD chromatogram of 0.005% (w/v) dextrose and 0.01% acid hydrolysate. (b) TLC chromatograms obtained before and after purification of CCK-oligosaccharides and acid-hydrolyzed CCK-oligosaccharides (M: glucose polymers G1–G7; B: before purification; A: after purification by Bio-gel P2; 1: 1% of acid hydrolysate; 2: 0.5% of acid hydrolysate; 3: 0.2% of acid hydrolysate).
