Electrophoresis buffers and transfer buffers are essential consumables in electrophoresis experiments. Many laboratories and researchers aim to save costs and improve experiment efficiency by reusing these liquids. However, the effectiveness of reusing electrophoresis buffers and transfer buffers is not consistent and must be adjusted based on actual usage. Here are some suggestions for reusing electrophoresis and transfer buffers, helping you improve experimental outcomes while ensuring accuracy.
Reusing Electrophoresis Buffers
The main function of the electrophoresis buffer is to provide ionic strength and facilitate the passage of current through the samples. In general, electrophoresis buffers can be reused 1-2 times, especially when prepared in-house. If the color of the buffer darkens or if there is an increase in impurities after reuse, it is best to prepare a new batch. Commercially prepared electrophoresis buffer powders tend to be more stable, and reusing the buffer 2-3 times is generally acceptable without significant performance degradation.
Tips for Use:
- Check for color changes or the presence of precipitates. If changes occur, do not reuse the buffer.
- Monitor the current and voltage during reuse to ensure consistent experimental conditions.

Transfer buffers are typically used to transfer proteins from the gel to the membrane in western blotting experiments. While most laboratories use constant current for protein transfer, special attention is required when reusing transfer buffers. During the second use, if the voltage drops significantly, it may indicate that the buffer’s efficiency has decreased or that protein transfer efficiency is reduced.

Tips for Use:
- If the voltage is noticeably lower during the second use, consider extending the transfer time to ensure complete protein transfer.
- If the voltage change is substantial, it is advisable to prepare a fresh transfer buffer to avoid affecting the experimental results, particularly for large molecular weight proteins.
Reusing electrophoresis buffers and transfer buffers can save costs, but it is important to make adjustments based on the actual conditions of the experiment. Always monitor voltage, current, and the status of the buffers to ensure accurate and reliable results for every experiment. With proper use and maintenance, you can maximize the performance of these reagents.
