Vector Laboratories

Developing innovative labeling and detection systems for biological and medical science

Vector Laboratories, part of Maravai LifeSciences, pioneered and has become 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 (VECTASTAIN® ABC kits) for immunohistochemistry and antifade mounting media for immunofluorescence (VECTASHIELD® Mounting Media), Vector has since introduced over 600 reagents and kits used by disease and therapeutics researchers from 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 Laboratories was founded in 1976 by Dr. Jim Whitehead, who dedicated the company to creating the highest performing products for researchers around the world. Vector Laboratories is online at

Since 1976 Vector Laboratories has provided innovative labeling and detection solutions to the scientific community. Shortly after introducing a line of purified lectin reagents, Vector Laboratories revolutionized the field of histological staining with development of the versatile and sensitive Biotin-Avidin detection method leading to the VECTASTAIN® ABC Kits/products. These reagents provide consistent, reliable, sensitive, and low background staining for immunohistochemistry and other applications.

Over the ensuing years, Vector Laboratories has continued to innovate with the development of key reagents including:
- the 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
- the acclaimed anti-fade VECTASHIELD® mounting mediums
- fluorescent products labeled with classic fluors as well as the new DyLight® dyes that allow superior fluorescence capabilities.

Recently, Maravai Life Sciences acquired TriLink Biotechnologies and decided to offer the SoluLINK Bioconjugation Product Range as part of Vector Laboratories. SoluLINK bioconjugation technology meets stringent requirements. It mildly, efficiently, and reproducibly conjugates and immobilizes all categories of biomolecules, including proteins, peptides, oligonucleotides, carbohydrates, drugs and surfaces. This chemistry is based on the reaction of an aromatic hydrazine with an aromatic aldehyde, which forms a stable bis-arylhydrazone conjugate bond. When functionalizing amines, S-HyNic is used to incorporate 6-hydrazinonicotinamide (HyNic) groups. This linker possesses a succinimidyl ester (NHS ester) that readily reacts with amino groups on proteins, other amine-containing biomolecules and surfaces using standard NHS ester reaction conditions. The aromatic aldehyde is incorporated on biomolecules with S-4FB in the same manner.

AdipoGen Life Sciences provides all SoluLINK Bioconjugation reagents through its partnership with Vector Laboratories. All SoluLINK Products are listed on our website with the starting abbreviation "VCS-". Please contact us if you request further information.

Featured Items

Vectashield® Vibrance™ Antifade Mounting Media with or without DAPI (VC-H-1700 & VC-H-1800)

VECTASHIELD Vibrance products are completely new formulations of curing antifade mounting media for immunofluorescence applications. These newest additions to Vector Laboratories VECTASHIELD portfolio were developed with customer feedback to improve on parameters such as ease of use and retention of specific staining intensity over time.

VECTASHIELD Vibrance Antifade Mounting Medium prevents rapid photobleaching of fluorescent proteins and fluorescent dyes on cell and tissue section preparations. VECTASHIELD Vibrance Antifade Mounting Medium is supplied as an aqueous, ready-to- use formulation which will cure (set) over several hours at room temperature to immobilize the coverslip. No further sealing of the coverslip is required. Each lot is tested for photobleaching retardance with qualitative and quantitative methods. VECTASHIELD Vibrance Antifade Mounting Medium is compatible with the majority of commercially available fluorescent dyes. The antifade properties of the medium are effective across the spectrum, including far red channels.

Why VECTASHIELD Vibrance Mounting Media?

> Superior antifade/anti-photobleaching properties across the spectrum
> Compatibility with commonly used fluorophores
> View sections one hour after mounting
> No tone or autofluorescent background, even after curing
> Room temperature storage of slides with extended archiving time
> Minimal bubble formation, even after several weeks storage
> Curing formulations with choice of counterstain (DAPI) or no counterstain
> 12 month product expiration date

Vector® TrueVIEW™ Autofluorescence Quenching Kit (VC-SP-8400)

Vector Laboratories introduces the TrueVIEW™ Autofluorescence Quenching Kit, offering the first effective technique for removing unwanted fluorescence in formalin-fixed paraffin embedded (FFPE) tissue samples, blood cells and structural elements such as collagen and elastin. Autofluorescence often impairs or prevents the use of immunofluorescence assays when the specific stained antigen cannot be distinguished from the interfering background signal. This is particularly problematic with tissue samples preserved using the FFPE method. TrueVIEW specifically targets background autofluorescence, and retains the intended specific fluorescent staining. TrueVIEW is effective across the spectral range from blue to far red and is compatible with commonly used fluorophores. This new quenching reagent enables researchers to identify specific markers that cannot be seen without removing the background noise of autofluorescence.

Applying TrueVIEW to sections is fast, requiring just five minutes for incubation. Ethanol steps and dilution are not required. The Vector TrueVIEW kit includes VECTASHIELD HardSet Antifade mounting media and contains enough reagent for between 100 and 150 tissue sections.
