Transfections allow for transient expression of a gene of interest in a target cell line and can be useful for short term studies of protein function. We specifically use this protocol with Lenti-X 293T cells, a cell line optimized for production of lentiviral vectors. Chloroquine contraindications Can i buy chloroquine over the counter Teva chloroquine Plaquenil ear pain For each lentiviral transduction, 0.25×10 6 NK cells per well were seeded in a 24-well plate BD Biosciences and mixed with an appropriate amount of virus supernatant in the presence of 8 μg/ml of protamine sulfate Sigma-Aldrich or polybrene Sigma-Aldrich in a final volume of no more than 1 ml. Abstract. Dendritic cells DCs are potent antigen-presenting cells APCs that play a pivotal role in stimulating antigen-specific T cells in vivo 1, 2cardinal properties of DCs are 1 the ability to take up, process, and present antigens; 2 the ability to migrate through different tissues into lymphoid organs; and 3 the ability to interact with and stimulate T cells. If kept for extended periods of time, chloroquine is toxic. The solution in the plates looks fuzzy, due to a very fine, dust-like precipitation of the transfection mixture. Note It is important to do all media changes with extreme gentleness, as the cells have been sensitized by the chloroquine, and can easily detach from the plate. Last Upload: June 10, 2016 Day 0: Seed Lenti-X 293T cells (this cell line is optimized for production of lentiviral vectors) Day 1 (pm): Transfect Cells Day 2 (am): 18h post transfection - Remove media, replace with fresh media Day 3 or more (am): Observe fluorescence, harvest cells, or perform your experiment *Pro-Tips* Different brands and lots of FBS can promote or inhibit transfection. This approach can be adapted for different cell lines and different transfection reagents.

The tax gene from HTLV-2 was fused with enhanced green fluorescence protein GFP, and the tax2-gfp fusion fragment was cloned into the lentivirus vector pLCEF8, in which the human elongation factor 1 α promoter drives expression of Tax2-GFP. HTLV-2 Tax Immortalizes Human CD4+ Memory T Lymphocytes by.. Production of Replication-Defective Retrovirus by.. Lentiviral Gene Ontology Vectors. For over a half-century the anti-malarial drug chloroquine CQ has been used as a therapeutic agent, alone or in combination, to treat autoimmune diseases. Lentivirus transduction into. Production, concentration and titration of pseudotyped HIV-1-based lentiviral vectors Robert H Kutner1, Xian-Yang Zhang1 & Jakob Reiser1,2 1Gene Therapy Program, Department of Medicine, Louisiana State University Health Sciences Center, 533 Bolivar Street, New Orleans, Louisiana 70112, USA. 2US Food Add 22 l of 25mM chloroquine to each 15cm dish for 10cm plate 7.8 l of chloroquinei.e. final concentration = 25 M. The cells should be transfected within 5-10’ of adding the chloroquine. 7. For 15cm plates, add 1.69ml of the transfection buffer to the DNA-CaCl2 solution by “bubbling”.
