Growth curve of H. pylori incubated with soluble CD43 having α1,4-GlcNAc-capped O-glycan (αGlcNAc (+)) and soluble CD43 lacking this O-glycan (αGlcNAc (−)). One milliunit (mU) of αGlcNAc (+) is defined as 1 μg of GlcNAcα-PNP. The protein concentration of αGlcNAc (−) is the same as that of 31.2 mU/ml of αGlcNAc (+).
