This depends on the particular situation, and the answer depends more on the coupled ligand than the resin itself. The most important criterion is to choose a buffer that is not harmful to the ligand. It is common to include 20% ethanol or preservatives like sodium azide or thimerosal (~0.02%) to inhibit potential bacterial growth.

How are proteins attached to the Cyanogen bromide-activated Sepharose® in Product C9142?
1 answer-
Coupling of molecules to CNBr-activated Sepharose® is usually via amine groups. In the case of proteins, this usually means the epsilon amines (exocyclic amines) of lysine groups.

What kind of volume should I use for my ligand to couple to the Cyanogen bromide-activated Sepharose®, Product C9142?
1 answer-
It is best that the coupling ligand should not be in too dilute a solution. In general, a volume ratio of 0.5 to 1 of coupling solution to CNBr-activated Sepharose® is recommended.

My ligand is in Tris buffer. Can I use Product C9142, Cyanogen bromide-activated-Sepharose®, with this sample?
1 answer-
Because Tris is an amine-containing buffer, we do not recommend coupling of samples in Tris buffer to the CNBr-activated Sepharose®. Tris will react with the CNBr groups and remove sites for ligand coupling. We would not recommend use of any amine-containing buffer in the coupling reaction. However, after the ligand has been added in the coupling reaction, then it is OK to use amine-containing buffers to block the remaining sites (e.g. ethanolamine, glycine).

After I've washed and prepared the resin in Product C9142, Cyanogen bromide-activated-Sepharose®, for the coupling reaction, how long can I wait before coupling the ligand to the resin?
1 answer-
We would recommend coupling the ligand immediately after washing and preparing the resin. This is because the reactive groups hydrolyze in the basic solution conditions of the preparation steps. The solutions used in the coupling reaction should also be kept cold (2-8°C) during the procedure.

Should I use a desiccator environment for storage of Cyanogen bromide-activated-Sepharose®?
1 answer-
It is a good idea to store the CNBr-activated agarose products in as dry an environment as possible, because the reactive groups are very moisture-sensitive.
