In column chromatography, it is put in the column to basically cleanse and lubricate. Generally, it helps to wash out any left-over proteins from a previous experiment. It can also help to separate the fractions that are collected.

Tris is used as a buffering agent in the elution buffer.

What considerations need to be made when choosing an elution buffer the mobile phase in a chromatographic run?

You need to consider the pH of the elution buffer of the mobile phase in a chromatographic run. You should work within 1 pH unit of the buffer pKa value.

What consideration is made when choosing an elution buffer?

One consideration to be made when choosing an elution buffer is to make sure the pH is within the range of the desires. Stabilizing components will help increase the solubility and stability of your solution.

Buffer solutions reduces the ionization during the elution in the column and gives a long life for Reverse phased columns.

Function of binding buffer?

When alkali or acid is added to a pH solution, a binding buffer will help prevent the pH from changing. There is also the elution buffer which is used to clean out any proteins which are leftover.

NaCl will not harm RNA. In fact, it is sometimes used as an elution buffer for RNA-Urea gels.

What is the function elution buffer during isolation of DNA?

Chromatography is the biotechnological technique whereby certain substances are separated from others by running a solution of them through a column. Parts of the solution we want will be trapped in the column, while those we don't will run right through the column. In this way we can set up a column so that DNA (particularly plasmid DNA), will become trapped in the column by some mechanism (often hydrophilic/hydrophobic affinity). When plasmid DNA is trapped in a column, during chromatography, it is the elution buffer which is responsible for washing it out of the column. The column is responsible for trapping DNA, while the elution buffer is what gets it out once the DNA is separate from the other parts of the mixture.

How does change in pH in elution buffer helps elute protein from ion exchange column?

Binding to a cation or anion exchange column requires a binding buffer that is below or above the pI of the protein (respectively) and therefore an appropriate protein ionization state for binding. In a practical sense, this means that if the pI of your protein is 7.0, you would need to below this (6.5 or below) in order to bind to a cation exchange column. Changing the pH of the elution buffer will change the ionization state of the protein and therefore exchange cations.
