What Vector Laboratories does
Vector Laboratories, Inc. is a private life science reagents company headquartered in Newark, California, founded in 1976 (per firmographic data; company history cites 1980) and operating under the ownership of Thompson Street Capital Partners (TSCP). The company supplies proteomics, glycomics, and bioconjugation tools to academic research institutions, biopharmaceutical developers, diagnostic companies, and contract manufacturing organizations, with its products cited in more than 350,000 scientific publications. Its catalog spans protein detection and visualization reagents (ImmPRESS polymer kits, VECTASTAIN avidin-biotin kits, VECTASHIELD mounting media, secondary antibodies, blocking reagents, and enzyme substrates), bioconjugation chemistry (the proprietary dPEG monodisperse PEG linker platform, SideWinder and BodyArmor ADC linker architectures, click chemistry reagents, fluorescent dyes, and payload delivery modifiers), and glycobiology products (lectins and the Glysite Explorer kit co-developed with Navinci).
The business operates a hybrid go-to-market model. Catalog products are sold directly through a self-serve e-commerce storefront on vectorlabs.com and through an international distributor network that expanded into the UK and Europe following the 2024 merger with Absolute Biotech. Higher-value enterprise services — including the BioDesign collaborative linker development process, custom bioconjugation, and the Absolute Antibody recombinant antibody sequencing and engineering platform (also serving LSBio's IHC-validated primary antibody catalog) — are delivered through direct account management under Statement-of-Work agreements. Catalog products carry publicly listed unit pricing typically between $162 and $706+, while custom volumes are handled via quote requests. Manufacturing is conducted at an ISO 9001:2015 certified facility.
Since 2023, the company has executed an aggressive platform expansion strategy under TSCP sponsorship, acquiring Click Chemistry Tools and Fluoroprobes (March 2023), Quanta BioDesign (July 2023), and merging with Absolute Biotech (May 2024) to broaden its bioconjugation IP base, expand manufacturing capacity, and extend its geographic footprint. The company employs between 251 and 500 people and is led by CEO Lisa Sellers.

Vector Laboratories competitors and assessment
Company assessmentBroad incumbents
- Leica Biosystems (Danaher): Leica Biosystems is a broad incumbent in IHC and pathology workflows, offering automated staining instruments (Leica Bond) and reagents that compete with Vector's ImmPRESS and VECTASTAIN detection kits. Vector's reagents are validated as compatible with Leica Bond, illustrating the tight customer overlap despite Leica being a much larger integrated supplier.
- Merck KGaA (Millipore Sigma): Merck's Millipore Sigma life science business competes with Vector across antibodies, detection reagents, and bioconjugation tools. As one of the largest life science suppliers globally, Merck offers overlapping products in protein chemistry, IHC, and western blot workflows with greater commercial reach than Vector.
- Thermo Fisher Scientific: Thermo Fisher Scientific is a broad incumbent offering competing antibody and detection reagent products through its Invitrogen and Thermo Scientific brands. Thermo Fisher's massive catalog, global direct salesforce, and bundled instrument-reagent offerings create significant competitive pressure on Vector across nearly every product category.
- Revvity (formerly PerkinElmer Life Sciences): Revvity is a broad incumbent in life science and diagnostics, offering reagents, detection kits, and automated platforms that overlap with Vector's IHC and protein detection products. Revvity's integrated instrument-reagent approach creates competitive pressure particularly in clinical and translational research applications.
Direct peers
- Abcam (Danaher): Abcam is a leading direct competitor in primary and secondary antibodies with a similarly large catalog of research-grade reagents used by academic and biopharma customers. Both companies compete in IHC, IF, and western blot applications, and Abcam's 2023 acquisition by Danaher intensifies competition for Vector's customer base.
- Santa Cruz Biotechnology: Santa Cruz Biotechnology is a direct competitor in research antibodies with broad catalog coverage spanning primary and secondary antibodies for IHC, IF, and western blotting. Both companies serve the academic research community with similar product categories and pricing structures.
- Bio-Rad Laboratories: Bio-Rad is a major direct competitor to Vector Laboratories in life science research reagents, particularly in protein detection, western blotting, and immunohistochemistry consumables. Both companies serve academic and biopharma customers with broad catalogs of antibodies, detection kits, and protein chemistry reagents.
- Cell Signaling Technology: Cell Signaling Technology is a direct peer in high-quality antibodies and reagent kits for signal transduction and protein detection research. Both companies focus on reproducibility and validation rigor, and compete for the same academic and biopharma researchers seeking validated IHC and western blot reagents.
- Rockland Immunochemicals: Rockland Immunochemicals is a direct peer in antibody production and customization, offering primary and secondary antibodies, ELISA kits, and custom antibody services to research and diagnostic customers. Both companies have private ownership structures and compete on customization capabilities and scientific support.
Emerging players
- GenScript: GenScript is an emerging player in custom antibody services and recombinant protein production, directly competing with Vector's Absolute Antibody subsidiary. Both companies offer antibody sequencing, engineering, and expression services to biopharma customers, with GenScript bringing significant scale advantages in Asia-Pacific markets.
