Abstract
nanoparticle transfection
Materials
Sodium acetate 25mM pH5
Polymer stock (100 ug/ul)
Desired media
Nanoparticle Synthesis
Defining Terms
  • DNA refers to nucleic acid cargo encoding genes of interest, generally stored at a concentration of 1 ug/ul.
  • Polymer refers to the Poly(beta-amino ester) (PBAE) that makes up the backbone of the nanoparticle.
  • Nanoparticle refers to the final complexed polymer + DNA that is ready for transfection.
DNA Dilution
For 3 technical replicate wells of one condition in 6-well plate format, mix the following in microcentrifuge tube.
  • 60 ul DNA at 1ug/ul
  • 440 ul sodium acetate
  • Total volume = 500 ul for 3 technical replicate wells per one condition
Polymer Dilution (7.2 mg.ml polymer concentration in NaAc)
For 3 technical replicate wells of one condition in 6-well plate format, mix the following in microcentrifuge tube.
  • 40 ul polymer (e.g. 4-5-6)
  • 460 ul sodium acetate
  • Total volume = 500 ul for 3 technical replicate wells per one condition
Nanoparticle (DNA+polymer) Synthesis
Combine diluted DNA with diluted polymer
  • Add 500 ul of diluted DNA to 500 ul diluted polymer (can freeze here at -80 at your own risk)
  • Add 5000 ul of serum containing media to 1000 ul NP's for final volume master mix of 6000 ul per condition
  • Incubate for 10 minutes
Transfection
  • Change media from each well of 6 well plate with 2000 ul nanoparticle master mix (media + nanoparticles)
  • Incubate for 24 hours or desired time
  • Change media after desired transfection time.
