What JS Link does

JS Link is a South Korea–headquartered, KOSDAQ-listed (ticker 127120) company operating two structurally distinct business divisions under a single corporate entity. The Biotech Division, marketed under the DNALINK sub-brand, delivers comprehensive genomic and proteomic analysis services — including next-generation sequencing (whole genome, exome/targeted, transcriptome, epigenome, single-cell), microarray analysis (GWAS, RNA, aCGH, CNV), genotyping (Fluidigm BioMark, TaqMan, SNaPshot), digital ELISA via SIMOA, proteomics on Olink and SomaLogic platforms, and spatial transcriptomics via NanoString GeoMX — alongside the ICS navigator kinship-identification program developed with Seoul National University College of Medicine through the Korea National Information Society Agency's 2024 Data Flagship Project. The Permanent Magnet Division manufactures neodymium-iron-boron (NdFeB) rare-earth permanent magnets for electric vehicle, wind energy, and electronics applications, operating a production facility in Yesan-gun, Chungcheongnam-do.

The company makes money through two revenue streams: professional services fees from the Biotech Division (sold to research institutions, hospitals, pharmaceutical clients, and government agencies, with 628 publications on record leveraging DNALINK services) and hardware sales from the Permanent Magnet Division (sold into automotive, wind energy, and electronics supply chains, with planned expansion to 3,000 tonnes/year capacity at a Lynas-partnered factory in Kuantan, Malaysia). Go-to-market is direct enterprise sales supplemented by strategic channel partnerships — most notably with Lynas Rare Earths (which invested approximately A$50 million in JS Link shares and is co-developing the Malaysia facility) and a non-binding LOI with REalloys Inc. for a fully integrated North American rare-earth magnet platform targeting U.S. defense, aerospace, automotive, robotics, and AI infrastructure customers. Pricing is not publicly disclosed for either division, indicating negotiated enterprise contracts. Operating geographies span South Korea and, with the Malaysia factory coming online, Southeast Asia; the North American platform remains at the LOI stage.

Core offering

JS Link operates two main business divisions: a Biotech Division (DNALINK) that provides comprehensive genomic analysis services including next-generation sequencing, microarray analysis, genotyping, digital ELISA, proteomics, and spatial analysis for research institutions and healthcare providers; and a Permanent Magnet Division that manufactures neodymium-iron-boron (NdFeB) rare earth permanent magnets for electric vehicles, wind energy, and electronics supply chains, with a planned 3,000 tonnes per year production facility in Kuantan, Malaysia through partnership with Lynas Rare Earths.

Product overview

JS Link operates as a dual-division company comprising a Biotech Division (바이오사업부) and a Permanent Magnet Division (영구자석사업부). The Biotech Division, branded as DNALINK, provides comprehensive genomic services including Next-Generation Sequencing (Whole Genome, De Novo, Exome, Transcriptome, Epigenome, Single Cell), Microarray Analysis (GWAS, RNA, aCGH, CNV), Genotyping (Fluidigm BioMark, TaqMan, SNaPshot), Digital ELISA (SIMOA), Proteomics (Olink, SomaLogic), and Spatial Analysis (GeoMX). The Permanent Magnet Division manufactures rare earth permanent magnets (NdFeB) for EV, wind power, and electronics supply chains, with current Korean operations and a planned 3,000-tonne-per-year facility in Malaysia through the Lynas partnership.
