About Since 1976 Vector Laboratories has provided innovative labeling and detection solutions to the scientific community. Shortly after introducing a line of purified lectin reagents, we revolutionized the field of histological staining with development of the versatile and sensitive Biotin-Avidin detection method leading to the VECTASTAIN® ABC family of products. These reagents provide consistent, reliable, sensitive, and low background staining for immunohistochemistry and other applications. Over the ensuing years, we have continued to innovate with the development of key reagents including: our ImmPRESS™ polymer detection systems – peroxidase micropolymers directly conjugated to secondary antibodies, which streamline detection procedures; the Vector® M.O.M.™ reagents, enabling the use of mouse primary antibodies on mouse tissue; proprietary enzyme substrates that yield a palette of colors for multiple labeling needs; our acclaimed anti-fade VECTASHIELD® mounting mediums, and our fluorescent products labeled with classic fluors as well as the new DyLight® dyes that allow superior fluorescence capabilities. Other pioneering products include neuronal tracers, ultrapure immunological products, and novel reagents for labeling, detection and isolation of nucleic acids, fusion proteins and carbohydrates. Vector Laboratories’ substantial presence in the scientific literature is a testament to the widespread use of our products and their quality. Vector Laboratories is an independent, privately-held California corporation with subsidiaries in the U.K. and Canada. The products listed in this catalog are manufactured at our main 65,000 ft2 research and development facilities in Burlingame, California. Our products are also available worldwide through a network of independent distributors. Throughout the years we have remained committed to producing superior products and supporting them with prompt and personal service. We have an accessible and knowledgeable technical staff ready to assist in the successful use of our reagents in a myriad of applications. Additional technical information and tutorials are available on our website. The long-term relationships we have established with members of the scientific community reflect a confidence in our record of producing products of unmatched performance and quality. Ours remains the standard by which others are measured. Vector Laboratories is now part of Maravai LifeSciences.
