Questions being answered:
Testing minimum siRNA for saturation
1.
What's lowest amount of siRNA I can use
2.
Is my midi for FF4 ok? --> Using 451 just in case
3.
Do I get same results in tHESC?

Lingering questions: if we are using a the Alexa Fluor.. how should we change set up?
0. Set Up
Inventory
siRNA at stock concentrations of: 50 uM in -80C, 1 uM in -20C
miRNA-ts choosen: miRNA-451 or FF4 (for 9, we don't have siRNA matching it)
Confirmed by miRAtlas to lack natural prescence in HEK293 cells
Purpose
With varying amounts of siRNA, how effective are miRNA-ts.
Plasmids to Transfect

Layout of Well Plate
siRNA added will probably be: 1, 2, 5, 10, 0 pmol
Need to replace 9 with FF4
Need to find out optimal amount of Lipo2K

2. ⌚Flick tubes gently and wait 5 minutes
3. Take 25 uL of DNA+siRNA and 25 uL of Lipo2k+Optimem and combine in one tube (per well)
4. ⌚Flick tubes gently and wait 20 minutes
5. Aspirate well and add 50 uL of transfection mixture + 450 uL of fresh media
Do this for a couple of wells at a time. Try to move quickly
