Arabidopsis thaliana Polar Glycerolipid Profiling by Thin Layer Chromatography (TLC) Coupled with Gas-Liquid Chromatography (GLC)

Composition of polar lipid extracts and the fatty acid composition of individual glycerolipids are determined in a simple and robust lipid profiling experiment. For this purpose, glycerolipids are isolated by thin layer chromatography and subjected to transmethylation of their acyl groups. Fatty acyl methylesters are quantified by gas-liquid chromatography.

Here, we describe the isolation of enteric-glial cells from the intestinal-submucosa using sequential EDTA incubations to chelate divalent cations and then incubation in non-enzymatic cell recovery solution. Plating the resultant cell suspension on poly-D-lysine and laminin results in a highly enriched culture of submucosal glial cells for functional analysis.
