TrueBlack® Lipofuscin Autofluorescence Quencher, 20X in DMF (Cat. No. 23007) is the original formulation. TrueBlack® Lipofuscin Autofluorescence Quencher, 30X in DMSO (Cat. No. 23011) is a newer, more concentrated formulation in DMSO, which is a less toxic solvent than DMF. The quencher stock solution formulation does not affect the performance in staining.
