Application

An immobilized metal affinity chromatography (IMAC) product that can be widely used for purifying proteins, peptides, and nucleotides of interest, most commonly proteins. IMAC-Select utilizes a non-charged linkage chemistry to connect the proprietary quadridentate chelate to the agarose bead matrix. IMAC-Select Affinity Gel is durable and can capture proteins of interest with an affinity to various metal ions such as nickel, cobalt, iron or gallium. A metal free resin allows researchers to add metal of choice, or to use the resin to remove metal contamination from a protein. IMAC-Select Affinity Gel has been used in the affinity purification of kelch-like ECH-associated protein 1 (KEAP1), Wilms tumor gene on the X chromosome (WTX) and glycoprotein G1 tail protein of the andes virus.

Physical form

1:1 suspension in a 30% ethanol solution

Preparation Note

The ethanol used to store the affiinity gel must be removed prior to use to avoid precipitation of buffer salts.The affinity gel is first washed with 1 to 2 volumes of deionized water to remove ethanol. The gel is charged with 2 to 3 volumes of a solution of the desired metal ion at a concentration of 10 mg/mL, and then equilibrated with 3 to 5 volumes of equilibration buffer.

Other Notes

Do not allow the affinity gel to remain in any buffer for extended periods of time unless it contains an anti-microbial agent such as 30% ethanol.

We present a gel-free proteomics procedure for the specific isolation of phosphorylated peptides from whole proteome digests. Central is the use of diagonal, reverse-phase chromatography which consists of two consecutive reverse-phase peptide separations with a modification step in between. The

In order to exploit human blood as a source of protein disease biomarkers, robust analytical methods are needed to overcome the inherent molecular complexity of this bio-fluid. We present the coupling of label-free SAX chromatography and IMAC to a data-independent
