NGS Adapters

Release Time:28 February, 2023

Building a gene library is a crucial step in the entire next generation sequencing (NGS) process, and the quality of the gene library directly impacts subsequent sequencing work. Typically, library construction protocols require end repair of fragmented DNA, followed by the ligation of adapters—specific sequences—at both ends to meet the read requirements of high-throughput sequencing platforms. High-quality adapters facilitate efficient connection with the fragmented DNA source, thereby enhancing library construction efficiency.

With years of DNA synthesis experience, Bioligo has optimized synthesis processes, rigorous quality control, and contamination prevention measures, ensuring the maximum efficiency of adapter connections.


As a crucial step in NGS, the generation of the sequencing library directly influences subsequent sequencing and data analysis. Typically, the library is constructed by performing end repair on fragmented DNA, attaching adapters with specific sequences to both ends, and then amplifying the DNA. This process creates a library that meets the requirements of NGS. High-quality adapters enhance the connection with fragmented DNA, thereby improving the efficiency of library creation.
