ECTASHIELD® Mounting Media are unsurpassed in preventing photobleaching. The different formulations of VECTASHIELD® Mounting Media all offer the same outstanding anti-fade and anti-photobleaching properties. They are all compatible with fluorescein, Texas Red®, AMCA, DyLight® dyes, Alexa Fluor® dyes, fluorescent nuclear stains, fluorescent proteins, fluorescent tracers, histochemical stains, and most fluorochromes.
Features of VECTASHIELD® Mounting Media:
- Inhibit photobleaching of most fluorochromes
- Available in non-hardening or hardening formulations
- Available with or without DAPI or propidium iodide
- No warming necessary
- Slides can be viewed after prolonged storage
- Continues to inhibit photobleaching after prolonged storage of mounted slides
- Easy to use
- Optically clear
- Ideal refractive index
The original VECTASHIELD® Mounting Medium is a glycerol-based, aqueous mountant that does not solidify but remains a viscous liquid on the slide. After mounting, coverslipped slides will not readily dry out and can be reviewed for weeks afterwards without sealing. For prolonged storage, coverslips can be permanently sealed around the perimeter with nail polish. Mounted slides should be stored at 4 ºC.
VECTASHIELD® Mounting Media are compatible with a wide array of fluorochromes, enzymatic substrates, and fluorescent proteins. Please consult the compatibility table （located in product information box） to determine if VECTASHIELD® will be compatible in your system.
Please note: VECTASHIELD® Mounting Medium may not be compatible with all enzymatic substrates or fluorescent proteins and test sections would be advisable when using anything other than commonly used fluorochromes.
The refractive index for VECTASHIELD® Mounting Medium is 1.44.

VECTASHIELD® Mounting Medium Antifade Comparison
Other manufacturers measure the antifade properties of their mountants using labeled microspheres or arrayed spots. Vector Labs prefers to measure antifade properties of VECTASHIELD® mountants using frozen tissue sections immunohistochemically stained with fluorescently labeled secondary antibodies.
Antifade capability is measured using a 40x objective with real time imaging over 30 seconds of continuous exposure to the excitation illumination. Individual intensity measurements are recorded from 6 separate labeled regions and the average is calculated. The intensity after 30 second exposure is expressed as a percentage of the intensity at zero time. The values for PG are taken from the manufacturer’s published results. |
