The core application of BIS-TRIS in protein electrophoresis
In protein electrophoresis, especially in isoelectric focusing (IEF) and two-dimensional electrophoresis (2-DE) experiments, the stability of pH gradient is crucial. BIS-TRIS, with its pKa value of 6.5, precisely fills the pH gap between the phosphate buffer system and the Tris buffer system, providing a smoother and more stable pH gradient for protein separation.
BIS-TRIS Powder
More importantly, the weak binding ability of BIS-TRIS to metal ions effectively reduces the interference of metal ions on protein migration, ensuring the accuracy and repeatability of protein separation. This advantage enables researchers to obtain clearer and more accurate protein separation results, laying a solid foundation for subsequent protein identification and functional research.
The unique value of BIS-TRIS in nucleic acid electrophoresis
In nucleic acid electrophoresis experiments, especially RNA electrophoresis, preventing nucleic acid degradation is the key to the success of the experiment. The BIS-TRIS buffer system can provide a mild separation environment and effectively reduce the risk of RNA hydrolysis. Meanwhile, its excellent buffer capacity ensures the stability of pH value during long-term electrophoresis, providing consistent environmental conditions for nucleic acid separation.
Compared with traditional buffer solutions, the BIS-TRIS buffer system can provide clearer nucleic acid bands and higher resolution, especially when separating small molecule nucleic acid fragments. This advantage makes BIS-TRIS the preferred buffer reagent for high-end nucleic acid electrophoresis experiments.
Why choose BIS-TRIS buffer
When choosing electrophoresis buffer reagents, researchers usually compare multiple options. BIS-TRIS stands out due to the following major advantages:
1. Wider buffering range: BIS-TRIS has excellent buffering ability in the pH range of 5.8-7.2, perfectly covering the isoelectric point range of many biomolecules.
2. Low metal ion binding force: This characteristic reduces the interference of metal ions on electrophoretic mobility, improving the accuracy and reproducibility of separation results.
3. High solubility: BIS-TRIS has extremely high solubility in water, making it easy to prepare high concentration reserve solutions and convenient to use.
4. Low temperature sensitivity: Its pKa value changes little with temperature, providing stability guarantee for experiments under different temperature conditions.
