In retroviral transduction experiments, B cells were depleted from the cell suspensions using the Dynabeads B220 depletion kit (Thermo Fisher, #11441D). The remaining T cells were cultured in the presence of 0.5 μg/ml anti-CD3 (500A2, Invitrogen, #16-0033-86) and anti-CD28 (37.51, Invitrogen, #16-0281-86) stimulating antibodies in complete DMEM (Sigma-Aldrich, #D5671) (supplemented with 2 mM L-Glutamine (Sigma-Aldrich, #G7513), 100 μg/ml Penicillin/Streptomycin (Sigma-Aldrich, #4333), 36 mg/l Asparagine (Sigma-Aldrich, #A4284), 1 mM Sodium-Pyruvate (Sigma-Aldrich, #8636), 10 ml/l Non-essential amino acids (Sigma-Aldrich, #M7145), 4 μl/l β-Mercaptoethanol (Merck KGaA, #805740) and 10% fetal calf serum (Sigma-Aldrich, #S0615)).
Anti cd28 37
The Anti-CD28 (37.51) is a laboratory reagent used for research purposes. It is an antibody that binds to the CD28 protein, which is expressed on the surface of T cells. The core function of this product is to facilitate the study of T cell activation and signaling pathways.

Murine T Cell Isolation and Transduction
For retroviral T cell transduction experiments, B cells from lymph nodes and spleens were first depleted from the cell suspensions using the Dynabeads B220 depletion kit (Thermo Fisher). The remaining T cells were then cultured in the presence of 0.5 μg/mL anti-CD3 (500A2, Invitrogen) and anti-CD28 (37.51, Invitrogen)-stimulating antibodies in complete DMEM (Sigma-Aldrich) [supplemented with 2 mM L-Glutamine (Sigma-Aldrich), 100 μg/mL Penicillin/Streptomycin (Sigma-Aldrich), 36 mg/l Asparagine (Sigma-Aldrich), 1 mM Sodium-Pyruvate (Sigma-Aldrich), 10 mL/l Nonessential amino acids (Sigma-Aldrich), 4 μL/l β-Mercaptoethanol (Merck KGaA), and 10% fetal calf serum (Sigma-Aldrich)] at a concentration of 2 × 106 cells/ml in a 12-well tissue culture plate (2 mL/well) for 2 d.
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.
