Isolation and Culture of Human and Mouse CD8+ T Cells

Buffy coats from de-identified healthy human blood donors were purchased from the Gulf Coast Regional Blood Center (Houston, TX); their acquisition or this purpose was approved by the MD Anderson Institutional Review Board. Peripheral blood mononuclear cells were isolated from buffy coat samples via centrifugation using the Ficoll-Paque method. Human CD8+ T cells were enriched from peripheral blood mononuclear cells using an EasySep human CD8+ T cell isolation kit (Stemcell Technologies, Vancouver, BC, Canada). These cells were cultured in a mixture comprising 45% RPMI-1640 medium, 45% Click medium (Sigma-Aldrich, St. Louis, MO), and 10% fetal bovine serum, referred to in some experiments as regular medium. Mouse CD8+ T cells were enriched from splenocytes using an EasySep mouse CD8+ T cell isolation kit (Stemcell Technologies). Mouse T cells were cultured in RPMI-1640 medium supplemented with 10% fetal bovine serum and 1% penicillin/streptomycin, and were activated with CD3/CD8 Dynabeads (Thermo Fisher Scientific, Waltham, MA), IL-12 (10 ng/mL), and IL-2 (50 U/mL) recombinant proteins. Supernatants of mouse T cell cultures after 24 h were used as conditioned medium.

T Cell Transduction with Truncated EGFR and murPRAME-TCR

Check if the same lab product or an alternative is used in the 5 most similar protocols
Leukapheresis samples from two healthy donors were purchased from the NIH Blood Bank (Bethesda, MD). Peripheral blood mononuclear cells (PBMC) were isolated using Histopaque (Sigma, Cat. 10771). T cells were stimulated using CD3/CD8 Dynabeads (Invitrogen, Cat. 11131D) in the presence of IL-2 (40IU, PeproTech, Cat. 200–02). After 48 hours of stimulation, T cells were transduced with a lentiviral vector containing truncated EGFR and murPRAME-TCR. Transduction efficiency was determined 4 days after transduction by flow cytometry using a tEGFR antibody (BioLegend, Cat. 352903).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
