RBITC, or Rhodamine B isothiocyanate, is a fluorescent dye known for its isothiocyanate group that can bind covalently to primary amines on proteins and biomolecules[1][2]. RBITC has a maximum excitation wavelength of 562nm and an emission wavelength of 582nm[3]. RBITC is primarily used in cell biology[4], molecular biology, and immunology for protein localization[5], cell tracking[6], and studying cellular processes[7].

البروتوكول (Protocol)
Experimental Protocol for Labeling Proteins with RBITC:
1. Preparation of RBITC Solution:Dissolve RBITC at 10mg/mL in DMSO before use. Mix thoroughly.
2. Preparation of Protein Solution: Dissolve target protein in 0.1M sodium phosphate, 0.15M NaCl buffer at pH 7.2 to form a 10mg/mL protein solution.
3. Labeling Reaction: Transfer the RBITC solution to the protein solution at a molar ratio of 5:1 and stir the mixture gently in the dark at 4°C for 12 hours.
4. Dialysis: Remove non-reacted RBITC by dialysis or with a Dye Removal Column.
5. After dialysis, collect the labeled protein solution, determine its concentration, and store RBITC-labeled protein at 4°C protected from light until ready to use.
This protocol only provides a guideline and should be modified according to your specific needs.
