Vector Laboratories

Founded in 1976, Vector Laboratories develops reagents, detection systems and enabling technologies that support protein analysis, tissue-based research, glycobiology and bioconjugation workflows. The company’s scientific expertise spans immunohistochemistry (IHC), immunofluorescence, flow cytometry and glycan analysis, providing researchers with tools for sensitive biomolecule detection, visualization and characterization. Its technologies help scientists investigate cellular and tissue biology, evaluate protein expression, study immune responses and profile complex glycans across a wide range of research applications, including immuno-oncology and infectious disease research. In addition to research reagents, the company offers custom manufacturing and bioconjugation capabilities for biomolecule labeling, functionalization and assay development.

The Vector Laboratories portfolio includes the VECTASTAIN® ABC detection systems, ImmPRESS® polymer-based detection reagents, VECTASHIELD® antifade mounting media, antigen retrieval reagents, blocking solutions, enzyme substrates, lectins, labeling reagents and affinity purification products. The company also provides conjugation chemistries, linkers, fluorescent dyes and PEG-based modification technologies used in biomolecule conjugation and therapeutic development workflows. These products support applications ranging from tissue staining and fluorescence imaging to glycan profiling, protein enrichment and biomolecule labeling.
