Proper drying of magnetic beads is a critical step to ensure optimal DNA recovery and purity. Beads should be dried just enough to eliminate any visible free-flowing liquid, while still retaining a shiny, dark brown appearance. This indicates they are ready for elution.
Avoid over-drying, as it can negatively impact DNA recovery. Over-dried beads typically appear matte and light brown and may be more difficult to resuspend.
