Fig. 6　Gelation test of GalNAc-suc-tail in various organic solvents for screening the tail module (the order of Rf value on silica gel TLC plate roughly indicates to the order of the molecular polarity of glycolipids, [glycolipid] = 25 mM). And the optimized screening of hydrogelator to obtain the stable hydrogel by using GalNAc-suc-glu(O-hexyl)2 as a lead compound.
