Buffers, Accessories & Background Quenchers

Wet-set antifade mounting medium for preserving fluorescence of our CF® dyes and other fluorochromes, in a dropper bottle for easy dispensing.

A buffer set that blocks non-specific antibody binding as well as direct interaction of fluorescent dyes on antibodies with cells or tissue sections.

A ready-to-use fixation solution for cells or tissues. Electron microscopy-grade, methanol-free paraformaldehyde, packaged under argon.

Suitable for use in molecular biology applications that require high quality, ultra-pure water.

Zwitterionic non-denaturing detergent for solubilizing membrane proteins for protein gels and assays.

An alternative to plastic microcentrifuge tubes for up to 200 uL sample volumes.

Nonionic detergent useful for solubilizing hydrophobic compounds to facilitate cell loading.

Additional concentrated cell lysis buffer that is designed for use with Biotium’s Firefly Luciferase Assay Kits when performing large sample volume assays.

Additional concentrated lysis buffer for use with our Renilla Luciferase Assay Kits in large volume assays.

Concentrated buffer used for Annexin V staining of cells to monitor apoptosis.

DTT (dithiothreitol) is a reducing agent commonly used to reduce cystine disulfides to free thiols.

TCEP hydrochloride is an odorless reducing agent that is more stable and effective than dithiothreitol (DTT) or 2-Mercaptoethanol. TCEP hydrochloride is soluble in water to 310 grams per liter.

Ready-to-use solution of Pluronic® F-127, a nonionic detergent useful for solubilizing hydrophobic compounds like AM esters of calcium indicator dyes to facilitate cell loading.

Ready-to-use solution of Pluronic® F-127, a nonionic detergent useful for solubilizing hydrophobic dye molecules such as AM esters of calcium indicator dyes to facilitate cell loading.

Probenecid is commonly used to inhibit organic-anion transporters located in the cell membrane. Such transporters can extrude dyes and indicators and thus contribute to low signal or high background in assays due to poor cellular retention of dyes.

Seals the edges of wet-mounted coverslips for fluorescence microscopy, with no ingredients that can leach into aqueous mounting medium and affect specimen fluorescence.
