Cost-reduction strategies in massive genomics experiments

Many modern biology studies require deep, whole-genome sequencing of hundreds to thousands of samples. Although per-sample costs have dramatically decreased, the total budget for such massive genome sequencing constitutes a significant barrier for poorly funded labs. The costly lab tools required for genomics experiments further hinder such studies. Here, we share two strategies for extensively reducing the costs of massive genomics experiments, including miniaturization of the NEBNext Ultra Ⅱ FS DNA Library Prep Kit for Illumina (reducing the per-sample total costs to ~ 1/6 of that charged by service providers) and in-lab 3D model-designing of genomics tools. These strategies not only dramatically release funding pressure for labs, but also provide students with additional training in hands-on genomics and 3D-model-designing skills, demonstrating the high potential for their application in genomics experiments and science education.
