What Arraystar does

Arraystar Inc. is a Rockville, Maryland-based biotechnology company founded in 2009 that operates a specialized contract research and reagent business focused on non-coding RNA (ncRNA) profiling and RNA modification (epitranscriptomic) analysis. The company sells fee-for-service microarray and next-generation sequencing workflows — including lncRNA, circRNA, small RNA, tRNA, tRF/tiRNA, glycoRNA, rG4 (RNA G-quadruplex), and R-loop profiling, as well as modification-specific assays for m6A, m5C, m1A, m7G, m3C, ac4C, Ψ, and o8G — to academic and pharmaceutical researchers. Its proprietary content libraries draw from FANTOM5 CAT, GENCODE, RefSeq, NONCODE, and internal discovery pipelines, with species-specific arrays for human, mouse, and rat, and it uses differentiated wet-lab methods such as MazF-based m6A mapping at single-nucleotide resolution and a "two-tailed qPCR" approach that elongates miRNAs at both ends to discriminate mature isoforms from precursors and isomiRs.

Commercially, Arraystar runs a sales-led B2B model with a global footprint: services are sold via direct quote requests, phone, and email, while reagent products (nrStar PCR arrays, rtStar cDNA synthesis kits, primer sets, master mixes, CUT&Tag library prep kits) are listed in an online storefront. Pricing is largely quote-based for services with frequent 15–30% promotional discounts, and products carry unit prices (e.g., miRNA PCR arrays at $1.00–$368 per plate). The customer base is horizontal and academic-heavy, with disclosed testimonials and use cases from Yale University, University of Pittsburgh, Henry Ford Hospital, and the University of Maryland School of Medicine. The company is privately held with no disclosed institutional funding, M&A activity, partnerships, or leadership changes in the source material.

The company's recent strategic emphasis is product-line expansion rather than scale: 2025 saw the launch of five new service offerings (mim-tRNA-Seq, rG4 microarray, m7G TRAC-Seq, m3C HAC-Seq, and GlycoRNA Array), extending coverage into emerging RNA biology areas (glycoRNAs, RNA G-quadruplexes, tRNA charging) and reinforcing its positioning as a one-stop ncRNA/epitranscriptomics specialist. With no public funding history and a headcount band of 11–50, Arraystar appears to operate as a bootstrapped or cash-generative niche CRO, monetizing both consumable reagent sales and full-service profiling projects.
