الوصف (Description)

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.

إرشادات عامة
اختر مذيبًا مناسبًا وفقًا لبيانات ذوبانية المنتج. بعد التحضير، قسّم المحلول المخزون إلى أجزاء لتجنب دورات التجميد والذوبان المتكررة.
استخدم المحاليل المخزونة خلال 6 أشهر عند حفظها في -80°C، أو خلال شهر واحد عند حفظها في -20°C.
لتحسين الذوبانية، سخّن الأنبوب إلى 37°C وعرّضه للموجات فوق الصوتية لمدة مناسبة.
شروط الشحن
تُشحن عينات التقييم مع عبوات تبريد. وتُشحن الأحجام الأخرى المتاحة في درجة حرارة الغرفة، أو مع عبوات تبريد عند الطلب.
