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

We designed a recyclable Hg(2+) probe based on Rhodamine B isothiocyanate (RBITC)-poly(ethylene glycol) (PEG)-comodified gold nanoparticles (AuNPs) with excellent robustness, selectivity, and sensitivity. On the basis of a rational design, only Hg(2+) can displace RBITC from the AuNP surfaces, resulting
