What is the difference between TrueBlack® Lipofuscin Autofluorescence Quencher (Cat. No. 23007, 23011) and TrueBlack® Plus Lipofuscin Autofluorescence Quencher (Cat. No. 23014)?

TrueBlack® Plus Lipofuscin Autofluorescence Quencher is the only lipofuscin quencher that can be used in aqueous buffer instead of 70% EtOH, allowing longer incubation times for thick tissue samples without shrinkage. TrueBlack® Plus offers even lower far-red background than the original TrueBlack® Lipofuscin Autofluorescence Quencher. It is recommended to review the staining protocol of TrueBlack® and TrueBlack® Plus to decide between the two.
