Description

General description

Rhodamine B isothiocyanate (RBITC) is a fluorescent dye. It acts as an anterograde and retrograde marker of retinal neurons in the adult rat. (current GD)It is also known as RBITC, RhIc, RITC, and TRITC.

Application

Rhodamine B isothiocyanate has been used as a fluorescent probe to label the pathogenic bacterium Staphylococcus aureus and is also used to label type I collagen (C1). Other applications include -

• labeling immunoglobulins
• as a fluorescent probe of living cells
• RBITC-Iabeled molecules like dextrans have been applied as probes of a cell′s endocytic activity and to mark cells to allow their subsequent migration to be detected
