TrueBlack® Lipofuscin Quencher can be used with the TrueBlack® IF Background Suppressor (Permeabilizing) kit in an immunofluorescence staining workflow, to reduce background from both non-specific antibody and dye binding, and autofluorescence arising from the sample itself. Because TrueBlack® IF reagents contain detergent, the TrueBlack® lipofuscin quencher would need to be used after immunostaining (Post-treatment protocol) as the latter is not compatible with detergents present in the IF reagents.
If immunostaining is performed with buffers lacking detergents, the TrueBlack lipofuscin quencher may be used before (Pre-treatment protocol) or after immunostaining.
