Buffers & Washes for Chromatography

Buffers and washes are important for purification of proteins in a chromatography system. In chromatography, the primary buffers help the proteins bind with ligands present in the matrix. To purify this sample an elution buffer, or wash, is used to separate out unwanted proteins. It is important for both types of buffers to be of high quality to ensure the maximum purity of your sample, and GoldBio provides a variety of buffers and washes at affordable prices.

I-901-25 25 mL $ 89.00
I-901-50 50 mL $ 135.00
I-901-100 100 mL $ 205.00
I-901-250 250 mL $ 459.00

Description

Imidazole is a planar 5-membered ring. It is a highly polar, highly water soluble amphoteric compound. Imidazole is often used to elute tagged proteins bound to metal ions attached to the surface of beads in a chromatography column by displacing the His-tag from the metal ion and freeing the His-tagged proteins.
