Dramatically Reduce Autofluorescence

 

Vector® TrueVIEW™ Autofluorescence Quenching Kit

Reveal true immunofluorescence—even in the most challenging tissues

In tissue sections, autofluorescence is the unwanted fluorescence that can make it difficult or impossible to distinguish antigen-specific signal from non-specific background. The novel, patent-pending Vector® TrueVIEW™ Autofluorescence Quenching Kit specifically binds and quenches autofluorescent elements from non-lipofuscin sources, significantly enhancing signal-to-noise in most immunofluorescence assays.

Why TrueVIEW™ Quencher?
  • Specific reduction of autofluorescence from non-lipofuscin sources
  • Easy-to-use, one-step method
  • Quick 5 min incubation
  • Compatible with a wide selection of fluorophores
  • Compatible with standard epifluorescence and confocal laser microscopes

WITHOUT Treatment

WITH Vector® TrueVIEW™ Quencher

 

Reduction of autofluorescence in human spleen using the TrueVIEW™ Autofluorescence Quenching Kit. Human spleen sections (FFPE) stained using mouse anti-CD20 (red) and rabbit anti-Ki67 (green) primary antibodies detected with VectaFluor™ Duet kit (DK-8818). Note significant reduction of autofluorescence in the treated section.

Comparison with other autofluorescence reducing agents

Whereas most methods for reducing tissue autofluorescence act primarily on lipofuscin granules, the Vector® TrueVIEW™ quencher targets fluorescence from non-lipofuscin sources, including aldehyde fixation, red blood cells, and structural elements, such as collagen and elastin. It provides a clear, unambiguous “true view” of target antigen localization, even in problematic tissues, such as kidney, spleen and pancreas.

Comparisons with other commercials and “home brew” approaches show that Vector® TrueVIEW™ is easier to use and more effective. The images below show the results of side-by-side comparisons on serial sections of formalin-fixed, paraffin embedded human pancreas visualized using a standard fluorescein (green) filter. No specific immunofluorescence staining was conducted.
