UDP-GlcNAc concentration in mouse tissues (pmol/mg tissue)
| Tissue | Mean | SD | Sample input, μg initial tissue mass | Recovery of 0.5 pmol exogenous UDP-GlcNAc, % |
|---|---|---|---|---|
| Liver | 241 | 57 | 3.4 | 109 |
| Kidney | 145 | 37 | 4.6 | 104 |
| Heart | 41.6 | 9.3 | 9.5 | 117 |
| Skeletal muscle (quadriceps) | 13.7 | 0.8 | 63.5 | 102 |
| Brain (cerebrum) | 62.6 | 7.4 | 9.9 | 135 |
Brain, n = 3 mice; all other tissues, n = 4 mice. Exogenous UDP-GlcNAc was spiked into replicate final extracts.
