VECTASHIELD® Antifade Mounting Medium with DAPI

Cat. No: H-1200
Price: $160.00
Unit Size: 10 ml


VECTASHIELD Antifade Mounting Medium with DAPI is a unique, stable formula for preserving fluorescence. VECTASHIELD Mounting Medium with DAPI prevents rapid photobleaching of fluorescent proteins and fluorescent dyes. VECTASHIELD Mounting Medium with DAPI does not solidify, but remains a liquid on the slide and can be stored without sealing.

More Information

VECTASHIELD Mounting Media are compatible with a wide array of fluorochromes, enzymatic substrates, and fluorescent proteins. Please consult the compatibility table (under the "Protocol/Data Sheet/SDS" tab) to determine if VECTASHIELD will be compatible in your system.

Both the VECTASHIELD HardSet and the original VECTASHIELD Mounting Media are available with or without the counterstain DAPI (4', 6-diamidino-2-phenylindole).  The DAPI concentration can be modified by mixing with the corresponding VECTASHIELD Mounting Medium without DAPI.  DAPI produces a blue fluorescence when bound to DNA with excitation at about 360 nm and emission at 460 nm. 

If desired, coverslips can be sealed around the perimeter with nail polish or a plastic sealant. Mounted slides should be stored at 4 °C, protected from light.

The refractive index for VECTASHIELD Mounting Medium is 1.45.

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.
