Tips include what to do following denaturation at 99°C, how to avoid evaporation from PCR tubes, and advice when adding reagents to a sample.
Always use a closed thermalcycler with heated Lid (105°C).

Following denaturation at 99°C for 20 minutes, immediately snap chill samples on wet ice or cold blocks. Do not leave in thermalcycler to ramp down to 4°C.

When adding reagents to the sample, ensure efficient mixing either by rapid pipetting or gentle vortexing. Failure to mix the reagents and samples properly could lead to inefficient sample labeling and dye incorporation or uneven hybridization of the labeled target to the arrays.

Ensure all reagents are defrosted and mixed before use. To ensure all reagents are at correct concentrations prior to use they should be thoroughly thawed but not above room temperature, efficiently mixed and then gently spun to collect contents at the bottom of tube.
