Immobilized metal affinity chromatography (IMAC) is the most widely used method to purify the proteins according to their affinity to specific metal ions, which was first introduced by Porath (1989). …
The column was charged with different metal ion (0.1 M NiSO 4 or CuSO 4) and the concentration of imidazole at elution buffer was varied (100, 200, 300, 400, 500, 600 mM). For protein analysis, the …
the glass or metal column tubing isfilled with small spherical inert supports. The liquid phase is adsorbed onto the surface of these beads in a thin layer. In a capillarycolumn,thetubingwallsarecoated …
In addition, multiply phosphorylated peptides are more enriched and the recovery of phosphopeptides appears to be largely dependent on the type of metal ion, column material and the elution procedure used. Recently, Ficarro et al. attained a much higher specificity using esterification of acidic residues before IMAC enrichment [26]. In this way ...
A laboratory-scale elution rig was commissioned to simulate Zadra and AARL carbon elution conditions, see Figure 1. The majority of the system was constructed from stainless steel tubing and Swagelok …

Protein renaturation and refolding can be performed prior to elution from the column. However, yields of recombinant proteins will be lower than under native conditions, because urea and guanidinium …
DURING HEAVY METAL ELUTION FROM A COLUMN PACKED WITH MUNICIPAL WASTE INCINERATION ASH At some point during acid leaching column tests of heavy metals from municipal waste incinera-tion ash, sudden and rapid elution of harmful elements was observed which was called the breakthrough (BT) phenomena.

Metal ions can exist in several different forms. The factors that determine the form of the metal ion are the extent of complexation and the oxidation state. ... column for 60 minutes with 1 M hydrochloric …
Poorly performing elution circuits leave excess metal loaded on the carbon, robbing it of the activity needed to completely remove precious metals from the last contact stage in the absorption circuit. …
Elution occurs by the interaction of a metal with greater ionic affinity with another metal of lesser affinity. This is most clearly demonstrated in the process of column chromatography, which …
Washing can be done by 100mM EDTA before charging the column with NiSO4. But elution buffer does not require EDTA. Use 200mM of imidazole in Tris buffer to elute your protein. …
Elution and recovery of captured His-tagged protein from an IMAC column is accomplished by using a high concentration of imidazole (at least 200 mM), low pH (e.g., 0.1 M glycine-HCl, pH 2.5) or an …
