Treatment:
Treatment ID: | TR002527 |
Treatment Summary: | Mice were anesthetized (using a combination of xylazine (80mg/kg) and ketamine (10mg/kg)) to allow removal of soleus and extensor digitorum longus (EDL) muscles. Upon removal, muscles were incubated at 22 oC in Ringer/MEM solution gas equilibrated with 95/5% O2/CO2 with appropriate 13C labeled substrates in a perfusion chamber routinely used for isolated muscle mechanics for 30 minutes. These included the following: 5.5 mM [U-13C6] glucose; 5.5 mM [U-13C3] pyruvate, or 16.5 mM [13C2] labeled Na-acetate. Following incubation, muscles were quickly removed, blotted, and then rapidly frozen in liquid nitrogen for subsequent NMR analysis. N=4 muscles were pooled into a single biological replicate of 30-50 mg tissue to afford detectable levels of substrates in the NMR analysis. |
