What exreprotein does
Exreprotein LLC (doing business as EXREprotein) is a Minneapolis-based, privately held manufacturer of life science research reagents operating from a single GMP-ready, animal-component-free production facility at its headquarters. The company sells a catalog of more than 230 products organized into nine categories: recombinant proteins/growth factors/cytokines, antibodies (loading controls, epitope tags, HRP-conjugated secondary antibodies), ELISA and ELISpot kits, serum-free cell culture media and kits under the EXREnu™ brand for lymphocyte, MSC, and NK cell workflows, Western blot and electrophoresis consumables under the EXREsolve™ brand, restriction endonucleases and other enzymes under the EXact-Cut™ brand, and a range of ready-to-use laboratory buffers. Recombinant proteins are positioned as ≥97% pure by SDS-PAGE and/or HPLC with endotoxin levels below 0.1 EU/µg (general research) or 0.01 EU/µg (sensitive cell-based assays), and the catalog spans sizes from 2 µg to 1 mg.
The underlying technology is in-house recombinant protein expression and purification across bacterial, yeast, insect, and mammalian systems, supported by custom codon optimization, lyophilized formats for stability, and the same GMP-ready facility for both catalog and contract manufacturing. Custom services — protein expression, antibody development, and ELISA kit customization — are delivered by doctorate-level scientists, positioning the company to serve bioprocess and cell-and-gene-therapy programs that require animal-component-free, GMP-grade inputs.
The business model is predominantly direct-to-consumer e-commerce through exreprotein.com with phone and email support, supplemented by an international distributor network and a Chinese-language site for non-U.S. markets. Pricing is pay-as-you-go unit pricing, with proteins ranging from roughly $50 to $5,899, ELISA kits standardized at $399.20, restriction enzymes at $39.20, and Western blot consumables from $23 to $799. Customer segments are horizontal: academic and government research labs, biopharmaceutical companies developing biologics, and cell-and-gene-therapy and immunotherapy researchers. Exreprotein is privately held with no disclosed funding rounds, ownership structure, or revenue.
