Autoradiograms of the TLC plates with authentic 14 C-labeled C16:0, C18:0, C18:1 and C20:4 FAMEs are shown. The AgNO 3 -TLC and reversed-phase TLC show that 14 C-oleic acid is incorporated into THPM TAG which is utilized to accumulate [ 14 C]oleate-labeled TAG inside Mtb . C , FAMEs prepared from THPM and Mtb TAG analyzed using a Varian CP-TAP CB capillary column attached to a Varian <t>CP-3900</t> gas chromatograph under a temperature control program.
