ABSTRACT
We report the successful application of selective excitation sculptured TOCSY NMR (SXS-TOCSY) to identify individual solution components from a heterogeneous system using selectively acquired (1)H NMR spin system patterns. SXS-TOCSY application is illustrated by detection of the simultaneous presence of poly-beta-(1,6)-N-acetylglucosamine (PNAG) and poly(glycerol phosphate) teichoic acid (TA) carbohydrate polymer components in crude biofilm extracts from Staphylococcus epidermidis without the need for further sample purification and component separation. Biofilms are implicated in the barriers for resistance of microbes toward antibiotics and immune responses, therefore efficient rapid detection and quantification of key components are important to assist in the design of a clinical infection response.
