About Us

Vector Laboratories, part of Maravai LifeSciences, pioneered and is a market leader in labeling and detection reagents for immunohistochemistry, immunofluorescence, glycobiology and bioconjugation. As the first company to commercialize avidin-biotin enzyme complex kits for immunohistochemistry and antifade mounting media for immunofluorescence, Vector has since introduced over 600 reliable reagents and kits. Its product catalog includes VECTASTAIN® ABC kits, VECTASHIELD® Mounting Media, ImmPRESS® Polymer Detection Kits, TrueVIEW® Autofluorescence Quenching Kit, ImmPACT® Substrates and SoluLINK® bioconjugation technology, which allows rapid, reproducible and quantifiable conjugation of all classes of biomolecules.

These time-tested tools and methods are used by disease and therapeutics researchers around the world--from academia to industrial and clinical settings--to accelerate their lab processes and improve productivity. In fact, Vector’s labeling and detection reagents and processes are included in Standard Operating Procedures in labs around the world.

Vector’s facilities are ISO 9001:2015 certified and its research contributions have been cited in more than 350,000 scientific publications. Located in the San Francisco Bay Area, Vector was founded in 1976 by Dr. Jim Whitehead, who dedicated the company to creating the highest performing products for researchers around the world. That same commitment is present today with the high level of both product and service that Vector Laboratories is known for.
