In weight loss programs, L-carnitine has long been valued for its ability to enhance energy and promote better fat utilization, especially when combined with increased physical activity
Immunofluorescence and confocal microscopy Cells were labeled at 37 C with 1 M SNAP-Surface 488 in HEPES-bicarbonate buffer (120 mM NaCl, 4.8 mM KCl, 24 mM NaHCO 3 , 0.5 mM Na 2 HPO 4 , 5 mM HEPES, 2.5 mM CaCl 2 , and 1.2 mM MgCl 2 , saturated with 95% O 2 /5% CO 2 , pH 7.4) plus 3 mM glucose and 1% BSA, stimulated with agonists at 11 mM glucose for the indicated times, fixed and processed for immunofluorescence with mouse anti-Rab11 (610657, BD Biosciences, 1/20) or anti-rodent GLP-1R monoclonal antibody (Mab 7F38, DSHB, 2 g l 1 ) plus Alexa Fluor 546 secondary (Life Technologies, 1/200), mounted in Prolong Diamond antifade reagent with 4,6-diamidino-2-phenylindole (Life Technologies) and imaged with a Zeiss LSM-780 inverted confocal laser-scanning microscope in a 63/1.4 numerical aperture oil-immersion objective and analyzed in Image J
