PTEN WT Rep1 | SA258359 | FL033158 | PTEN Wild-Type | Genotype |
Collection:
Collection ID: | CO002666 |
Collection Summary: | PTEN WT and KO MEFs were seeded at 80% in 10cm plates 24 hours prior to metabolite extraction/sample prep |
Sample Type: | Fibroblasts |
Treatment:
Treatment ID: | TR002685 |
Treatment Summary: | Cells did not undergo any treatment. They were cultured for 24 hours in 10cm plates with DMEM media containing 10% FBS, 1% Pen/strep, and an additional 1% of glutamine |
Sample Preparation:
Sampleprep ID: | SP002679 |
Sampleprep Summary: | Media was fully removed from the plates. Metabolites were extracted using ice cold 80% methanol and dried using a speed vac. The dried metabolites were sent to the Mass Spec Core ran by John Asara at the Beth Israel Deaconess Medical Center at Harvard University for targeted LC-MS/MS. For detailed sample prep information see the attached protocol. |

MS Comments: | Selective reaction monitoring, SRM, of endogenous water-soluble metabolites was performed for steady state analysis. The positive ion mode ESI voltage was +4900. Dwell time was set to 3ms per SRM transition and 1.55 seconds was the total cycle time. Retention time 15-20 seconds. MultiQuant v2.1 software was used to in integrate peak areas for each metabolite SRM transition |
Ion Mode: | POSITIVE |
