What BioLegend does

BioLegend, headquartered in San Diego, California, is a life science reagent manufacturer specializing in antibody-based products, recombinant proteins, immunoassays, and cell separation tools for biomedical research and clinical applications. Its core catalog spans flow cytometry reagents (including Brilliant Violet™ and StarBright™ dyes), MojoSort™ magnetic cell separation kits, LEGENDplex™ multiplex immunoassays, ELISA kits, recombinant cytokines and growth factors, and the TotalSeq™ family of oligonucleotide-conjugated antibodies that bridge protein detection with single-cell RNA/DNA sequencing on 10x Genomics, Illumina, and Mission Bio platforms. The company also operates a GMP-compliant Cell-Vive™ ancillary materials portfolio for cell and gene therapy bioprocessing and a clinical IVD/ASR product line under ISO 13485:2016 quality systems.

The business operates a hybrid go-to-market combining direct e-commerce (biolegend.com and regional storefronts), field sales representatives for bulk and custom work, and an authorized distributor network covering more than 90 countries, with wholly-owned regional entities in the UK, Netherlands, Japan, China, and Germany. Revenue is generated primarily through one-time catalog sales of catalog antibodies, proteins, and kits, supplemented by professional services (custom conjugation, custom immunoassay development) and managed services (GMP contract manufacturing). Pricing is unit-based for standard SKUs and quote-based for custom and bulk orders. BioLegend has been a wholly-owned subsidiary of Revvity — the S&P 500 health science company spun off from PerkinElmer in 2023 with $2.7B+ in 2023 revenue — since the 2021 acquisition, and serves pharmaceutical/biotech firms, academic institutions, government research programs, clinical laboratories, and biopharmaceutical manufacturers across more than 190 end markets.

Direct peers

• Bio-Rad Laboratories: Bio-Rad is BioLegend's most direct competitor in flow cytometry reagents and is also a technology partner (StarBright™ dyes are powered by Bio-Rad). Both companies sell antibody panels, dyes, and instrumentation consumables to immunology, cancer, and cell biology researchers globally.
• BD Biosciences: BD Biosciences is a leading provider of flow cytometry instruments and reagent kits, including fluorescent antibodies, multiplex bead arrays, and clinical IVD flow cytometry products. It directly competes with BioLegend in clinical and research flow cytometry and is a global incumbent in the installed-instrument base.
• Miltenyi Biotec: Miltenyi Biotec is a global competitor in magnetic cell separation (MACS®), flow cytometry reagents, and cell therapy manufacturing reagents — directly competing with BioLegend's MojoSort™ and cell-therapy-adjacent reagent portfolio. It has built an end-to-end cell therapy manufacturing offering that parallels Cell-Vive™.
• Cell Signaling Technology (CST): CST is a leading provider of highly validated antibodies and reagents, with a strong reputation in cell signaling, cancer, and neuroscience research — directly comparable to BioLegend's content library and validation-led positioning. CST competes on antibody specificity, reproducibility, and application support across Western blot, IHC, and flow cytometry.
• Bio-Techne (R&D Systems / Novus Biologicals / Tocris): Bio-Techne is a major competitor in recombinant proteins, cytokines/growth factors, ELISA kits, and research antibodies (via R&D Systems, Novus, and Tocris). It overlaps directly with BioLegend's recombinant protein and immunoassay businesses, including in GMP and cell therapy reagent adjacencies.
• Abcam: Abcam is one of the largest research antibody catalog businesses globally, offering polyclonal, monoclonal, and recombinant antibodies across essentially the same research applications as BioLegend (flow cytometry, IHC, Western blot, IF). It is a direct horizontal competitor in catalog antibody breadth and pricing.
• Cytek Biosciences: Cytek is a leading provider of spectral flow cytometry instruments and reagents; it directly competes with BioLegend in advanced flow cytometry workflows and benefits from instrument–reagent cross-selling similar in concept to BioLegend's Brilliant Violet™ and StarBright™ reagent strategies.

Broad incumbents

• Thermo Fisher Scientific (Invitrogen / eBioscience / Gibco): Thermo Fisher's life sciences brands (Invitrogen, eBioscience, Gibco, Thermo Scientific) offer an overlapping portfolio of research antibodies, recombinant proteins, cell culture reagents, and flow cytometry consumables. As a large incumbent, it competes with BioLegend across most catalog reagent categories and benefits from a much broader instrument and services footprint.

Emerging players

• 10x Genomics: 10x Genomics is BioLegend's single-cell sequencing platform partner (TotalSeq™ is compatible with 10x workflows) and an emerging adjacent player in single-cell multiomics reagents. It is a peer in the broader single-cell ecosystem where strategic choices by 10x can materially affect TotalSeq™'s positioning.
• Standard BioTools (formerly Fluidigm): Standard BioTools markets the CyTOF®/Hyperion® mass cytometry platform and Maxpar® metal-tagged antibody panel reagents — BioLegend sells Maxpar® Ready antibodies into the same workflow, making Standard BioTools a partially overlapping player in high-parameter cellular profiling.
