Sulforhodamine B has been used as a dye in the MCF-7 (human breast adenocarcinoma cell line) cell proliferation assay.

For R&D use onlynot for drug household or other uses.

Sulforhodamine B (SRB) is a bright-pink aminoxanthene dye. The sulforhodamine B (SRB) assay is extensively used forin vitrocytotoxicity screening. SRB binds to the protein constituents of the cells in a stoichiometric manner. Thus the amount of dye extracted from stained cells is directly proportional to the cell mass. SRB can also be used for cell density determination.
