Technical Info/Product Notes: | For in vitro stimulation we recommend the following procedure: 1. Bone marrow-derived mouse dendritic cells (BM mDC) are cultured 8x104/100μl in RPMI containing 10% FCS over night at 5% CO2 and 37°C. 2. The medium is removed and replaced by 100μl OPTI MEM (Invitrogen) and subsequently the transfection mixture is added: 25μl OPTI MEM containing 0.025 to 0.25 Poly(dA:dT) + 25μl OPTI MEM containing 0.5μl Lipofectamine 2000 (Invitrogen) or alternative transfection agents. 3. Over night stimulation at 5% CO2 and 37°C. 4. Measurement of IFN-α/β in culture supernatants. |
