我的转膜缓冲液的pH值偏离推荐值0.2单位，能否继续使用？

我们建议丢弃缓冲液，并在再次检查试剂和水的纯度后重新配制。不建议用酸或碱调节pH，因为这会使缓冲液的电导率升高，导致转印期间电流过高。

What type of transfer buffer should be used with Invitrogen Tricine gels?

For non-sequencing applications, any transfer buffer used with Tris-Glycine gels can be used with Tricine gels including Tris-Glycine transfer buffer. For sequencing applications, the buffer should be chemically compatible with sequencing protocols. Non-glycine based transfer buffers such as the NuPAGE Transfer buffer, 1/2X TBE Transfer buffer, or CAPS Buffer can be used for N-terminal sequencing . Generally, a pH which is close to neutral is desirable to maintain gel and protein stability. High current should be avoided because it can lead to heat generation and instability.

When blotting with the XCell II Blot Module, what would happen if I filled the outer buffer chamber with transfer buffer instead of water?

This is perfectly acceptable with the XCell II Blot Module. The liquid in the outer buffer chamber only serves as a coolant or heat sink. The reason why water is recommended is because it is a less expensive alternative.

The pH of my transfer buffer deviates from the recommended value by 0.2 units. Can I still use the buffer?

We recommend discarding the buffer and remaking it after rechecking the reagents and the water purity. We do not recommend adjusting the pH with acid or base, as this will increase the conductivity of the buffer and result in higher current during the transfer.
