Pharmacology
MeSH Pharmacological Classification
Chemicals that emit light after excitation by light. The wave length of the emitted light is usually longer than that of the incident light. Fluorochromes are substances that cause fluorescence in other substances, i.e., dyes used to mark or label other compounds with fluorescent tags.
Cellular LocationsCytoplasm
Uses & manufacturing
General Manufacturing InformationXanthylium, 3,6-bis(diethylamino)-9-(2,4-disulfophenyl)-, inner salt: ACTIVE
Applications
UsespH 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 DescriptionSulforhodamine 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.
