Blocking Buffers & Background Quenchers

This unique reagent quenches lipofuscin autofluorescence in tissue sections for immunofluorescence staining and can also help to reduce autofluorescence from other sources like extracellular matrix.

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

Buffer system optimized for fluorescence-based western provides superior specificity, sensitivity, and background suppression.

A solution of cold water fish skin gelatin that can be added to blocking buffers to minimize non-specific antibody binding in immuno-detection procedures such as western blotting and cell staining.

Can be used as a stabilizing agent for proteins and enzymes, or added to blocking buffers to minimize non-specific antibody binding in immuno-detection procedures such as western blotting and cell staining.

Can be used as a stabilizing agent for proteins and enzymes, or added to blocking buffers to minimize non-specific antibody binding in immuno-detection procedures such as western blotting and cell staining.

A blocking agent commonly used to minimize background noise in immunodetection procedures such as western blotting and immunostaining.

Gelatin from fish skin that can be added to blocking buffers to minimize non-specific antibody binding in immuno-detection procedures such as western blotting and cell staining.

Quench lipofuscin autofluorescence in PBS, with minimal background.

SCAS (4-Sulfonato calix[8]arene, sodium salt) is a quencher developed by Biotium to reduce background fluorescence when using our fixable AM dyes, SynaptoGreen and SynaptoRed dyes. Unlike ADVASEP-7, SCAS dramatically lowers background fluorescence as soon as it is added to the preparation without the need for repeated wash steps.
