Having buffers such as Tris present can help protect against this; while these solutes also undergo transient concentration shifts during freezing and thawing, the ratio of acidic to basic forms of the buffer pair should remain nearly constant and help prevent pH swings in the resulting microenvironments.
Each buffer system is made up of two compounds, together referred to as a buffer pair.
Note that each buffer system is in equilibrium, meaning that there is continual adjustment in the ratio of the acid (proton donor) to base (proton acceptor) members of the buffer pair.
