TitleDonor 2 1g 0 hr
Source nameT-cells, peripheral blood
DescriptionPeripheral blood leukocytes of three human donors were isolated from blood bank buffy-coat preparations by Ficoll-Hypaque density gradient centrifugation, and T-cells were purified with high affinity negative selection human CD3+ T-cell enrichment columns. The cells were resuspended in RPMI-1640 with 10% FCS with approximately 3-8 million cells/mL at room temperature overnight. T-cells were then either unactivated (1g 0 hr), activated (1g 4 hr) with a final concentration of 5 µg/mL Con A + 4 µg/mL anti-CD28 antibody and incubated for 4 hours at 37°C, or loaded onto a RPM rotating at 60°/s. T-cells loaded on the RPM were cultured for 2 hours prior to collection or activation to allow equilibration of cells to the new environment. After incubation, 1 mL of 4 M guanidinium isothiocyanate in 750 mM sodium citrate buffer, pH 7, with N-lauroylsarcosine and ß-mercaptoethanol was added to lyse cells and stabilize RNA. Lysates were frozen at –80°C. Lot batch = 2001663
