Abstract
Type I lipoteichoic acid (LTA) is a glycerolphosphate polymer found in the cell envelope of diverse Gram-positive bacteria. The glycerolphosphate backbone is often further decorated with D-alanine and/or sugar residues. Here, we provide details of a 1-butanol extraction and purification method of type I LTA by hydrophobic interaction chromatography. The protocol has been adapted from methods originally described by Fischer et al. (Eur J Biochem 133:523-530, 1983) and further optimized by Morath et al. (J Exp Med 193:393-397, 2001). We also present information on a 2D nuclear magnetic resonance (NMR) analysis method to gain chemical and structural information of the purified LTA material.
