Pool the samples amplified using the same indexed primer together. If the variation in amplification success is large, estimate concentrations and pool the samples in equimolar ratios. This can be done using some gel documentation systems or Fragment Analyzer/Tapestation/Bioanalyzer. Alternatively, concentrations can be measured using Qubit/Picogreen but the samples have to be purified using AMPure beads before quantification (in order to remove primer-dimers).

After pooling, perform AMPure cleanup in order to remove primer-dimers, with the beads:sample ratio 0.7:1 according to the manufacturer's instructions. Resuspend in 15 μl of 10 mM Tris or water.

Prepare the hybridization mix. Probes and blocking oligos are used in excess. So far, we used 500-1000 ng of the Illumina library and the same amount of the probes.

Incubate at 95°C for 10 minutes, then at 65°C for 48 hours. Mix from time to time. The best is to use rotor in the hybridization oven, but it is also possible to use a standard PCR machine.
