How do you transfect Jurkat cells?
Transfection of Jurkat Cells Plate 1 x 105 cells per well in 0.5 ml of complete growth medium. Cell density should be ~80% confluent on the day of transfection. For each well of cells to be transfected, dilute 0.5 μg of DNA into 100 μl of Opti-MEM® I Reduced Serum Medium without serum.
What does PEI do in transfection?
DNA can be introduced into a host cell by transfection with polyethylenimine (PEI), a stable cationic polymer (Boussif et al., 1995). PEI condenses DNA into positively charged particles that bind to anionic cell surfaces.
How do you use transfection on PEI?
Gently add the diluted PEI to the diluted DNA. Add the diluted PEI dropwise while gently flicking the diluted DNA tube. Incubate the mixture 15-20 min at room temperature. Carefully transfer the transfection mix to the Lenti-X 293T packaging cells.
How does PEI work?
PEI condenses DNA into positively charged particles, which bind to anionic cell surface residues and are brought into the cell via endocytosis. Once inside the cell, protonation of the amines results in an influx of counter-ions and a lowering of the osmotic potential.
What is PEI pro?
PEIpro® is a ready to use 1 mg/ml optimised linear polyethylenimine (PEI) reagent for the production of virus & recombinant proteins by Transient Gene Expression (TGE) in suspension-adapted mammalian cell lines cultivated in shaker flasks, platform shakers or stirred tank bioreactors.
What is PEI coating?
PEI (Polyetherimide), also known as Ultem, is a reusable “relatively maintenance free” build surface for both ABS (with a Heated Bed) and PLA (hot or cold) requiring no additional adhesives such as glue or tape. PEI is appealing due to its “no-surface-prep” conditions, which make it convenient to work with.
What is PEI for?
The synthetic polycation polyethylenimine is used to condense plasmid DNA into positively charged 100 nm complexes. These PEI–DNA complexes are then bound to adenovirus particles through charge interactions with negative domains on the viral hexon.
Which is the best way to transfect Jurkat cells?
Best media – RPMI, best method for gene transfer – lentivirus. For transfection – electroporation is best. for siRNA transfection of JURKAT cells my colleagues use Viromer BLUE (from Lipocalyx). By using Viromers they get up to 70% transfection efficiency. Viromers are synthetic polymers which are zero in charge.
How much PEI is needed for transfection of cells?
For transfection, add the expression vector plasmid DNA to the cells at a final concentration of 3 µg/ml and PEI. to a final concentration of 9 µg/ml of transfection volume. (DNA concentration may be varied from 1-6 µg/ml to. optimize expression, while PEI is maintained at 9 µg/ml).
How can I grow Jurkat cells in RPMI?
Jurkat cells maintained in RPMI with L-glutamine (Cat. No. 11875-085) supplemented with 10% fetal bovine serum (Cat. No. 26140-079), and 0.1 mM MEM Non-Essential Amino Acids Solution (cat. No. 11140-050). Grow cells at 37°C with 5% CO 2. Lipofectamine® LTX Reagent (store at +4°C until use), and PLUS™ Reagent (if desired; store at 4°C)
