6X GelRed® Prestain Loading Buffer with Tracking Dye

6X GelRed® Prestain Loading Buffers are DNA gel loading buffers containing GelRed® for one-step fluorescent staining and gel loading of DNA. Choose loading buffer with two blue tracking dyes or loading buffer with orange tracking dye.

TrueBlack® WB Blocking Buffer Kit

The TrueBlack® WB Blocking Buffer Kit is a ready-to-use buffer system that provides optimal specificity, sensitivity, and background signal suppression for fluorescence-based western blotting (WB).

NucView® 488 Caspase-3 Assay Kit for Live Cells

NucView® 488 Caspase-3 substrate is a novel cell membrane-permeable fluorogenic caspase substrate designed for detecting caspase-3 activity within live cells in real time.

MemBrite™ Fix Cell Surface Staining Kits

MemBrite™ Fix Cell Surface Staining Kits provide a convenient way to visualize cell boundaries in multicolor staining experiments. Staining is rapid and uniform, with a wide choice of colors. MemBrite™ Fix dyes covalently label the surface of live cells. The staining withstands fixation and permeabilization for subsequent immunofluorescence staining.

Mix-n-Stain™ CF® Dye Antibody Labeling Kits

Mix-n-Stain™ antibody labeling kits are a revolutionary antibody labeling technology that allows you to label your antibody with one of our superior CF® dyes in 30 minutes without a purification step. The labeling procedure tolerates many common buffer components and antibody stabilizers. Now with an extended shelf life of at least 1 year.

TrueBlack® Lipofuscin Autofluorescence Quencher

TrueBlack® Lipofuscin Autofluorescence Quencher, 20X in DMF, is a new reagent for quenching lipofuscin autofluorescence in tissue sections for immunofluorescence staining. It can also help reduce autofluorescence from other sources like extracellular matrix.

AccuBlue® Broad Range RNA Quantitation Kit

Broad Range RNA Quantitation Kit designed for use with fluorescent microplate readers or with small fluorometers such as the Qubit® fluorometer (from Thermo Fisher Scientific). The assay is specific for RNA, and can quantify RNA samples in the range of 0.5-100 ng/uL.

AccuGreen™ High Sensitivity dsDNA Quantitation Kit

The AccuGreen™ High Sensitivity dsDNA Quantitation Kit is designed for use with handheld fluorometers such as the Qubit® fluorometer from Thermo Fisher. The AccuGreen™ kit is specific for dsDNA, and can quantify DNA samples in the range of 0.01-10 ng/uL.
