Collection:
Collection ID: | CO003281 |
Collection Summary: | The E2a cells (106) were cultured in CMM for no more than 2 passages before intravenous tail vail injection to B6 mice 3 days before CAR-T cell injection. The E2a-bearing mice were irradiated with 500cGy sublethal dosage the day before CAR-T cell injection. The murine CD8 CAR-T cells were generated and expanded with rhIL-2 (60 IU/ml) as described above. The expanded CD8 CAR-T cells were washed with PBS, and 106 CAR+ cells were injected into the E2a-bearing mice via intravenous tail vail injection. The mice were followed for survival with the humane end point of development of hind limb paralysis, or weight loss of more than 20% of the original weight, or signs of major discomfort as determined by the institutional veterinarian. |

Treatment Summary: | Metabolomics differences in this experiment are observed at baseline |
Sample Preparation:
Sampleprep ID: | SP003295 |
Sampleprep Summary: | CAR-T cells were isolated as described above either from in vitro culture or from bone marrow harvested in an in vivo study. The cells were washed in PBS and frozen at -80C until the assay is ready to run. Metabolites from cells were extracted at 2x106 cells/ml at 4°C (30 min) in the presence of 5:3:2 MeOH:MeCN:water (v/v/v). The samples were spun down and the resulting supernatant was transferred to new tubes and dried under a vacuum. The resulting residue was reconstituted in 0.1% formic acid at a 3x concentration, then analyzed on a Thermo Vanquish UHPLC coupled to a Thermo Q Exactive MS as previously described in detail. |
