Collection:
Collection ID: | CO003279 |
Collection Summary: | Human CD8 cells were isolated with positive selection as described. The CD8 cells were activated with anti-CD3/anti-CD28 beads (Dynabeads™ Human T-Expander CD3/CD28, Gibco), as previously described107. After 48h activation, the CD8 cells were spun (1000xg for 2h at 32C) with lentiviral supernatant containing CD19-BBz/shMCJ-1 CAR, CD19-BBz/shMCJ-2 CAR or CD19-BBz/shMCJ-2 CAR construct-packing virus with rhIL-2 (40 IU/ml) and protamine sulfate. After transduction, the anti-CD3/anti-CD28 beads were removed and CD8 cells were expanded with rhIL-2 (100 IU/ml) for the specified number of days. |

Treatment:
Treatment ID: | TR003295 |
Treatment Summary: | The human CD19-BBz shRNA CAR lentiviral constructs were based on a previously described CD19-BBz CAR containing the human CD19-binding scFV FMC63, CD8 hinge domain, 4-1BB costimulatory domain and CD3 chain105. Using CD19-BBz CAR plasmid as a cloning vector, we generated multiple vectors where we incorporated the RNA polymerase III U6 promotor (on the 3' of the CD3 chain domain) followed by an shRNA: 1) a CD19-BBz/shMCJ-1 CAR construct containing the shMCJ-1 5’-GAAGATTTCAACTCCTAGC-3’ sequence106, 2) a CD19-BBz/shMCJ-2 CAR construct containing the shMCJ-2; 5’-AACCTCTAGAACAAGTTATC-3’, and 3) a CD19-BBz/c-shRNA CAR vectors expressing the shRNA encoding scramble sequences. Lentiviral supernatant was produced in the LentiX-293T packaging cell line (Clonetech) as previously described. Lentiviral supernatants were collected after 48 hours post-transfection. |
Sample Preparation:
Sampleprep ID: | SP003293 |
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. |
