Sample Preparation:
Sampleprep ID: | SP002702 |
Sampleprep Summary: | 10 µl of plasma or 300 µl of tissue homogenate prepared at 100 mg/ml in 3M perchloric acid containing isotopically labeled internal standards KIC-d3, KIV-5C13, (Cambridge Isotope Laboratories), and KMV-d8 (Toronto Research Chemicals) are precipitated with 150 µl of 3M PCA. 200 µl of 25 M o-phenylenediamine (OPD) in 3M HCl is added to the supernatants and the samples are incubated at 80oC for 20 minutes. Keto acids are extracted with ethyl acetate. The extracts are dried under nitrogen and reconstituted in 200 mM ammonium acetate. |

Chromatography Summary: | The analytical column is used at 30°C. 10 µl of the sample are injected onto the column and eluted at a flow rate of 0.4 ml/min. The gradient begins with 45% eluent A (5 mM ammonium acetate in water) and is then programmed as follows: 0 to 2 min – gradient to 55% eluent B (methanol); 2 to 2.5 min - gradient to 95% eluent B; 2.5 to 3.2 min - hold at 95% eluent B, return to 45% A, and re-equilibrate the column at initial conditions for 1 minute. |

Instrument Name: | Waters Acquity UPLC |
Column Name: | Waters Acquity UPLC BEH C18 (50 x 2.1 mm,1.7 um) |
Column Temperature: | 30C |
Flow Gradient: | 45% A and 55% B for 2 minutes, followed by a linear gradient to 95% B from 2 to 2.5 minutes, held at 95% B for 0.7 minutes, returned to 45% A, and finally the column was re-equilibrated at initial conditions for 1 minute. The total run time was 4.7 minutes. |
Flow Rate: | 0.4 ml/min |
Solvent A: | 100% water; 5 mM ammonium acetate |
Solvent B: | 100% methanol |
