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. Hydroxychloroquine package insert pdf Plaquenil uses arthritis Simpler—no additional reagents required for boosting lentiviral production e.g. chloroquine phosphate, sodium butyrate, caffeine. Faster—time to virus collection is 24 hours less than other reagents, and reverse transfection time is almost 2 days less than other reagents with comparable viral titers. I have different protocols for Lentivirus production using Lipofectamine transfection of HEK293T cells and now am confused about the concentration of Chloroquine and Na-Butyrate. MM chloroquine diphosphate Dissolve 0.129 g of chloroquine diphosphate salt in 10 mL of sterile water. Filter sterilize through a 0.22 μm filter. Aliquot 50-100 μL and store at -20 ℃. Aliquots can be thawed and stored at 4 ℃ prior to use. Thawed aliquots should be discarded after 1-2 months. 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.

Transfection of 293T cells - Lentiviral Gene Ontology Vectors. Addgene Lentivirus Production Protocol. What is the best applicable inhibitor of autophagy?. 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 The provided production medium does not contain chemicals used to add lentivirus production such as sodium butyrate, caffeine, or chloroquine. So, lentivirus in this medium can be directly used for most of applications. 3. Reagents for purification and long-term storage are included. 4. Chloroquine is an inhibitor of the lysosomal degradation of the DNA which is taken up by the cells, so as leelee said, transfection should have been successful, albeit at a slightly lower level than if you would have added the chloroquine. In my normal transfections, I never add chloroquine and get high efficiencies nevertheless.
