Buffers, Accessories, & Background Reducers

GelRed® Agarose LE is  pre-coated with GelRed® Nucleic Acid Gel Stain for simple preparation of precast gels. With no need to handle concentrated fluorescent dye while preparing your gel, GelRed® Agarose offers greater convenience and safety.

GelGreen® Agarose LE is  pre-coated with GelGreen® Nucleic Acid Gel Stain for simple preparation of precast gels. With no need to handle concentrated fluorescent dye while preparing your gel, GelGreen® Agarose offers greater convenience and safety.

High performance agarose for nucleic acid electrophoresis (analytical or preparative) and blotting. Validated for use with Biotium’s GelRed®, GelGreen®, and DNAzure® gel stains.

5X TBE (Tris-Borate-EDTA) is a concentrated buffer solution in deionized water. TBE is used for polyacrylamide and agarose gel electrophoresis.

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.

The TrueBlack® Background Suppressor System is designed for optimal blocking of non-specific antibody binding as well as direct interaction of fluorescent dyes on antibodies with cells or tissue sections.

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).

Wet-set antifade mounting medium optimally formulated for preserving fluorescence of our CF® dyes and other fluorochromes.  Dropper bottle makes for quick and easy dispensing. Available with or without DAPI.

A revolutionary antifade mounting medium optimally formulated for preserving fluorescence of our CF® dyes and other fluorochromes. EverBrite™ Hardset mounting medium hardens at room temperature completely in 24 hours.

A revolutionary antifade mounting medium optimally formulated for preserving fluorescence of our CF® dyes and other fluorochromes. Available with or without DAPI.

Flow Cytometry Fixation/Permeabilization Kit contains optimally formulated buffers for fixation and permeabilization of suspension cells for immunofluorescence staining of intracellular antigens for analysis by flow cytometry. Note: the fixation buffer in this kit is prepared from methanol-stabilized formaldehyde. For methanol-free fixative, see our Paraformaldehyde, 4% in PBS, Ready-to-Use Fixative.

Paraformaldehyde, 4% in PBS is a ready-to-use fixation solution for cells or tissues. It is electron microscopy-grade paraformaldehyde dissolved in pH 7.4 PBS, and is stabilized by packaging under argon with no methanol added.

10X Fish Gelatin Blocking Agent is a solution of cold water fish skin gelatin that can be added to blocking buffers to minimize non-specific antibody binding in immunodetection procedures such as Western Blotting and immunostaining. Unlike BSA or milk, fish gelatin does not contain IgG or serum proteins that could cross-react with mammalian antibodies.

Molecular biology grade 10X phosphate-buffered saline (PBS). RNase-, DNase-, protease-free.

Bovine serum albumin (BSA) is commonly used as a stabilizing agent for proteins such as antibodies and enzymes, and as a blocking agent to reduce non-specific protein binding in immunoassays such as ELISA, immunofluorescence staining, and Western blotting. This is a 30% solution of BSA in water, prepared using IgG- and protease-free BSA.

Bovine serum albumin (BSA) is commonly used as a stabilizing agent for proteins and enzymes, including dilute solutions of antibody and use as a blocking agent to reduce non-specific binding. This BSA is protease- and IgG-free.
