CEL-Seq protocol validation

  • Protocol modified to use common sequence primer with Illumina 5' Adapter and T7 promoter (CS-5primeAD-T7).
  • 100 ng/ul total RNA will be used as input (from Rui).
  • I will work with 16 tubes at a time.
  • For one set of 16 tubes, I want 2 x 1 ng rxns (+ control), 12 x 100 pg rxns (experimental), and 2 x no RNA (no template controls, NTC).
  • For the second set of 16, I want 2 x 100 pg rxns (+ control), 12 x 10 pg rxns (experimental, approx. single cell amount), and 2 x no RNA (NTCs).
  • Keep all RNA on ice at all times.
  • Work in the hood. EtOH, RNase away, and UV treat all surfaces and tools. UV treat water for dilutions.
  • Use low-bind tubes.

Prep

  • Sample layout is as follows:
Sample # RNA input Sample # RNA input Sample # RNA input Sample # RNA input
1 1 ng 9 100 pg 17 100 pg 25 10 pg
2 1 ng 10 100 pg 18 100 pg 26 10 pg
3 100 pg 11 100 pg 19 10 pg 27 10 pg
4 100 pg 12 100 pg 20 10 pg 28 10 pg
5 100 pg 13 100 pg 21 10 pg 29 10 pg

7 100 pg 15 NTC 23 10 pg 31 NTC
8 100 pg 16 NTC 24 10 pg 32 NTC
  • Barcoded RT primers are in 48 wells of a 92 well plate at 200 uM each, in the following layout:
Barcode number 1 2 3 4 5 6 7 8 9 10 11 12

  • Serial dilutions will be necessary to dilute the RT primers to the correct concentration.

Dilute RT primers to appropriate concentrations

  1. Dilute primers to 32 pmol/ul, 3.2 pmol/ul, and 0.32 pmol/ul, depending on input (Note that each primer must be diluted separately for each sample):
    1. Add 16 ul of 100 pmol/ul primer to 84 ul H2O --> 100 ul 32 pmol/ul primer. Use 0.5 ul of this per 1 ng total RNA.
    2. Add 10 ul of 32 pmol/ul primer to 90 ul H2O --> 100 ul 3.2 pmol/ul primer. Use 0.5 ul of this per 100 pg total RNA.
    3. Add 10 ul of 3.2 pmol/ul primer to 90 ul H2O --> 100 ul 0.32 pmol/ul primer. Use 0.5 ul of this per 10 pg total RNA.
  2. Dilute total RNA to 2 ng/ul, on ice:
    1. Add 1 ul 100 ng/ul RNA to 9 ul H2O --> 10 ul 10 ng/ul RNA.
    2. Add 2 ul 10 ng/ul RNA to 8 ul of H2O --> 10 ul 2 ng/ul RNA.
