Vector® TrueVIEW™ Autofluorescence Quenching Kit
Product description
Features:
- Removes unwanted autofluorescence in tissue sections due to aldehyde fixation, red blood cells, and structural elements such as collagen and elastin
- Improves overall signal-to-noise in most immunofluorescence assays
- Effective on problematic tissues such as kidney and spleen
- Easy-to-use, one-step method
- Compatible with a wide selection of fluorophores
- Compatible with standard epifluorescence and confocal laser microscopes
Tissue autofluorescence often occurs with aldehyde fixation or from inherent native tissue components (collagen, elastin, and red blood cells). The extent and intensity of autofluorescence background frequently makes it difficult or impossible to distinguish specific signals in immunofluorescence applications.
Most methods for reduction of tissue autofluorescence act primarily on lipofuscin granules, and are not broadly effective against the most common sources of autofluorescence targeted by Vector® TrueVIEW™ Quencher.
The Vector® TrueVIEW™ Autofluorescence Quenching Kit provides a novel way to diminish unwanted autofluorescence from non-lipofuscin sources and dramatically improve signal-to-noise ratio. The quenching action of the kit reagents provides a clear, unambiguous, “true view” localization of the target antigen.
Current methods for reducing autofluorescence primarily include “home brew” concoctions such as sodium borohydride and other ink-based products. These methods are essentially ineffective against aldehyde induced autofluorescence. In contrast, Vector® TrueVIEW™ reagent binds to hydrophilic compounds and effectively quenches endogenous autofluorescence.

Easy To ApplyFollowing completion of the IF staining procedure: |
Mode of ActionFollowing completion of the IF staining procedure: |
Signal to Noise OptimizationThe primary antibody and detection reagents should be optimized ( titered) in conjunction with Vector® TrueVIEW™ Quenching Kit to achieve maximum signal to noise. |
Optimization of ExposureIncreasing exposure times may be necessary to achieve optimal image acquisition for TrueVIEW™ Quencher treated slides. |
Comparison between Vector® TrueVIEW™ reagent and other autofluorescence reducing agentsWe compared the effectiveness of Vector® TrueVIEW™ quenching action in parallel with other commercially available autofluorescence reducing products and "home brew" reagents, on serial sections of formalin- fixed, paraffin-embedded human pancreas visualized using a standard fluorescein (green) filter. No specific immunofluorescence staining was conducted. The images below highlight our results. All images were acquired under identical conditions (including microscope objective and exposure times). |
