Title: Innovations by Sung-Min Chun in DNA Library Preparation

Introduction

Sung-Min Chun is a notable inventor based in Seoul, South Korea. He has made significant contributions to the field of molecular biology, particularly in the preparation of DNA libraries from formalin-fixed, paraffin-embedded (FFPE) tissues. His work addresses critical challenges faced in genomic analysis, especially with older FFPE samples.

Latest Patents

Sung-Min Chun holds a patent for a method titled "Method for preparing DNA library derived from FFPE tissue using endonuclease." This invention provides a solution for preparing DNA libraries from FFPE tissues, which are commonly used in clinical samples. The method utilizes S1 nucleases, which specifically cleave single-stranded DNA, to facilitate the extraction of genomic DNA (gDNA) from FFPE tissues. By treating and eluting S1 nucleases under appropriate conditions, the process allows for the acquisition of DNA fragments suitable for library preparation, thereby omitting the Covaris fragmentation process. This innovation not only reduces costs but also saves time in the preparation of DNA libraries.
