    Schematic overview of the experimental workflow for partial metabolic labeling. Mice with full-thickness burn injury and sham-treated controls were maintained on diets containing (isopropyl- 2 H 7 ) or natural L-Leu for 7 days. Liver tissue from the 2 groups of animals (n=3) were harvested and homogenized on Day 7. The homogenates were sonicated and subjected to 3 freeze-thaw cycles. Hydrophobic components were removed by chloroform extraction. A: corrected relative quantification for partially labeled SILAM. The intensity of unlabeled parent ion from burned animals (obtained by enrichment C1) was subtracted from the MS ion intensity of the corresponding light peptide after mixing the tissue samples. Unambiguous characterizations of partially metabolically labeled liver Akt1/PKBα were achieved with the isotope dilution method and MS/MS sequence information (A2, B2 and C2). B: relative quantification of liver Akt1/PKBα after burn injury. A mixture of the exact amounts (2 g each, isotope dilution) of liver from burned (heavy isotope labeled) and sham-treated (light isotope labeled) mice was homogenized and immunoprecipitated. The free cysteine residues were acetylated with iodoacetyl-LC-biotin at room temperature for 15 min followed by quenching with 2-mercaptoethanol. The beads were then heated at 95°C for 5 min and kept at room temperature for 30 min prior to <t>SDS-PAGE.</t> Biotinylated peptides, including the kinase loop peptide 290 ITDFGLCK 297 , were captured with immobilized monomeric avidin beads. The control peptide, 252 FYGAEIVSALDYLHSEK 268 located just outside of the kinase loop (for assessment of kinase protein level after injury) was obtained from supernatant (B1). Unambiguous confirmations of the peptides and the expected labelings were obtained from singly charged y ions (B2). C: Akt1/PKBα enrichment determination. Akt1/PKBα was immunoprecipitated and free cysteine was biotinylated as described above. Doubly and triply charged tryptic peptides were analyzed with nano-LC interfaced with Q-TOF micro tandem mass spectrometry (C1). Partially labeled parent ions with MS difference of 3.5 Da (doubly charged under ESI) were confirmed via their singly charged heavy y ions with MS difference of 7.0 Da (C2). The monoisotopic parent ion ratio of non-labeled (M+2H + ) and labeled (M+7+2H + ) peptides represents the metabolic labeling efficiency of one instance of (isopropyl- 2 H 7 )-L-Leu incorporation after burn injury. This is an updated proteomic version of classical isotope internal standard characterization.
