This kit is a dedicated kit for the QKGEN® Transposase Rapid DNA Library Prep Kit (for MGI-SI), which provides 96 index primers that can be used to construct second-generation sequenced libraries with 96 different index labels. When using this kit to construct a library for BGI platform sequencing, BGI's official high-throughput sequencing primer kit (TM), item number: 1000013816, needs to be installed separately, and cannot be mixed with BGI common library sequencing. All reagents provided in the kit have undergone strict quality control and functional verification to ensure the stability and repeatability of the library construction to the greatest extent.
