What LongSeq does

LongSeq (legal entity LONGSEQ APPLICATIONS, S.L.) is a privately held genetic analysis service provider founded in 2020 and headquartered in Churra, Murcia, Spain. The company is an official service provider of Oxford Nanopore Technologies and operates a 10-product portfolio of long-read nanopore sequencing services spanning whole-genome sequencing (human, plant, animal, bacterial), targeted region sequencing via PCR and enrichment, full-transcript RNA sequencing, 16S metagenomics, de novo assembly, tandem repeat characterisation, plasmid sequencing (Plasmi-seq), a hereditary cancer panel covering 200+ genes (Hereditary-Cancer-Seq), and retrotransposon analysis (RetroSeq). The technical differentiator is the ability to resolve complex genetic cases — structural variants, tandem repeat expansions, retrotransposon insertions, haplotype phasing, and methylation — on unmanipulated native DNA/RNA using MinION, GridION, and PromethION devices, with average read lengths around 10 Kb for whole genomes and approximately 780 bp in RNA sequencing. End-to-end delivery includes project advisory, library preparation, sequencing, and proprietary bioinformatics pipelines bundled into the service, with a 2-4 week sample-to-data turnaround.

The company is structured around an interdisciplinary team drawn from the University of Murcia, IMIB (Instituto Murciano de Investigación Biomédica), and Hospital Morales Meseguer, combining molecular biology, medicine, pharmacology, and computer engineering. Customers include biomedical researchers, the agri-food sector, veterinary researchers, and R&D companies; a documented case study is with the Haematology and Oncology Group at Morales Meseguer Hospital for antithrombin deficiency. Commercial go-to-market is sales-led, quote-based, accessed via the website contact form and a client portal. The company has also developed educational channels (nanopore sequencing courses and workshops) that serve as a top-of-funnel engagement layer. In 2024 it received non-dilutive EU FEDER project funding via INFO Murcia under the RIS4 2021-2027 strategy, and in 2026 it announced a tertiary-analysis integration with SeqOne and collaborations with VarSome, reflecting an ecosystem-buildout strategy around the core Oxford Nanopore platform.

Products and services

• Genomic (Whole Genome Sequencing) Whole genome sequencing service (human, plant, animal, bacterial) using MinION, GridION, or PromethION devices, producing ultra-long reads from unmanipulated material for structural variant characterization, complex variant identification, epigenetic modification detection, and haplotype determination. Targeted at biomedical researchers, clinical researchers, and agricultural/veterinary scientists with cases that short-read sequencing cannot resolve.
• Targeted Region (PCR) Sequencing of PCR products without fragmentation, enabling high-depth analysis with multiplexed samples to reduce cost. Applications include biallelic mutation studies, low-frequency SNP analysis, haplotype studies, and CRISPR-Cas9 cleavage evaluation. Targeted at researchers performing targeted genetic studies at high depth.
• Targeted Region (Enrichment) Real-time sequencing directed to genomic regions of interest up to 3 Mb without DNA manipulation, achieving greater depth of coverage in the desired region. Supports biallelic mutations, low-frequency SNP analysis, haplotype studies, and population studies. Aimed at researchers needing targeted depth without amplification steps.
• RNA Sequencing Direct sequencing of whole transcript reads using ultra-long reads of native RNA or cDNA without fragmentation or amplification. Enables characterization of complete transcripts, splicing variants, fusion genes, new isoforms, epitranscriptomic modifications, antisense transcripts, and lncRNA isoforms. Targeted at researchers requiring full-length transcript analysis.
• Metagenomics 16S Complete 16S rRNA gene sequencing enabling accurate identification of closely related species, full transcriptomic analysis of microbial RNA, real-time species identification, microbial resistance, and virulence factor determination.
