LC-MS (negative ion mode) identification of mycolic acids released from mAGP after LysB treatment. (a) Total ion chromatograms from non-treated and treated (LysB) mAGP samples. (b) The negative ion mass spectra (averaged from 19 to 25 min) of non-treated and treated mAGP samples from m/z 920 to 1232. The mAGP sample treated with LysB showed the presence of several peaks, identified as mycolic acids. α, α-mycolates; α′, α′-mycolates; e, epoxy mycolates. The ion at m/z 980 corresponds to a calibration reference compound.
