Sample Preparation:
| Sampleprep ID: | SP002770 |
| Sampleprep Summary: | 500 ul of tissue homogenate preprared at 50 mg/ml in 50% acetonitrile/0.3% formic acid are spiked with C17 Acyl CoA. The acyl CoAs are purified by solid phase extraction using 2-(2-pyridyl) ethyl functionalized Silica gel (Sigma-Aldrich 54127-U). |

| MS Comments: | Ion ratios of endogenous acyl CoAs to the C-17 CoA internal standard are computed from centroided spectra using a software package NeoLynx (Waters, Milford, MA). The ratios are converted to concentrations using calibrators prepared by spiking tissue homogenates with authentic CoAs (Sigma, St. Louis , MO) having saturated acyl chain lengths C0- C18. Corrections for the heavy isotope effects, mainly 13C, to the adjacent m+2 spectral peaks in a particular chain length cluster are made empirically by referring to the observed spectra for the analytical standards. The values are expressed in pmol/mg. Spectra are acquired in the multichannel acquisition mode monitoring the neutral loss of 507 amu (phosphoadenosine diphosphate) and scanning from m/z 750 to1060. |
