Rhodamine B isothiocyanate

Rhodamine B isothiocyanate is stable, but may be sensitive to light or moisture. It should be stored in a dark and dry place. It is incompatible with strong oxidizing agents. It is often used as a red fluorescent marker for proteins. 

Rhodamine B isothiocyanate is a mixture of isomers for fluorescence applications including fluorescent marking of proteins (labelling efficiency with bovine serum albumin >70%). It is a derivative of phenolphtalein.

Storage conditions: 2-8°C,Store dark and dry.

                                      Protein Fluorescent Labeling. Plant cell culture medium.

Rhodamine B isothiocyanate (RBITC) is a fluorescent dye. It acts as an anterograde and retrograde marker of retinal neurons in the adult rat.
Rhodamine B isothiocyanate (RhBITC) is a prototype dye molecule that is widely used as a fluorescent tag in a variety of biological applications. 
Rhodamine B isothiocyanate has been used as a fluorescent probe to label pathogenic bacterium Staphylococcus aureus and is also used to label type I collagen (C1).


Rhodamine B isothiocyanate Uses The Principle

1. Use natural pigments widely recognized internationally;
2. Coloring foods that countries have determined can be colorized;
3. The amount of pigment added when coloring food should be lower than the control of high content;
