SULFORHODAMINE B Chemical Properties,Usage,Production

Chemical Properties

dark green crystalline powder

Uses

pH sensitive of SRB towards it reactivity to living cells renders it useful for scaling drug induced cytotoxicity and cell proliferations. SRB assay was used to monitor the enzymatic activity of living cells.

General Description

Sulforhodamine B (SRB) is a fluorescent protein dye. It was reported that the dye binds itself to the amino acid residues of tricholoroacetic acid fixed cells in mild basic conditions and extracts itself into the solution under mild acidic conditions.

in vivo

Lissamine rhodamine B can be used as an aradiotracer for imaging tumor mice by positron emission tomography (PET)^[2].
