Prepare Sample Pre-Mix and Samples
All DNA samples need to be added into the sample pre-mix individually, prior to loading the
sample mix solutions into the sample inlets of an IFC.
Prepare the Sample Pre-Mix Solution
1 Working in a DNA-free hood, combine the components listed in the table below. This
protocol prepares enough sample pre-mix for 60 reactions. This is enough reagent to
load one IFC with 12 additional reactions to compensate for dead volume and pipetting
error.
Table 8. Sample pre-mix solution
2 Vortex the sample pre-mix for a minimum of 20 seconds and centrifuge for 30 seconds.
Prepare the Sample Mix Solutions
1 Combine the components listed below in a 96-well plate to prepare 48 individual sample
mix solutions.
