±×¸² 1. ThruPLEX¢ç¸¦ ÀÌ¿ëÇÑ single-tube workflow
Create indexed libraries starting with cell-free DNA in three simple steps: end repair, adapter ligation, and high-fidelity library amplification. No purification or sample transfer steps are required. The streamlined workflow is performed in two hours in a single tube or well, preventing sample loss and enhancing positive sample identification.
