Type of support UNOsphere S UNOsphere Q
Binding Capacity 12 mg protein/column* 36 mg protein/column*
Column bed volume 0.2 ml 0.2 ml
Binding buffer 20 mM sodium acetate, pH 5.0 20 mM Tris, pH 8.3
Elution buffer Binding buffer + 1.0 M NaCl Binding buffer + 1.0 M NaCl
* Binding capacity determined using IgG (CEX) and BSA (AEX). Capacity will differ slightly depending on the protein.
Fractionation by Charge

Fractionation by charge — Chromatographic methods also can fractionate specifically or generally. Aurum ion exchange (AEX and CEX) mini columns allow selective purification of either acidic or basic proteins. Easy-to-use Aurum ion exchange kits selectively enrich either acidic or basic proteins and can be used with a variety of starting samples.

Total protein sample AEX-bound sample CEX-bound sample

Fractionation of rat brain tissue using Aurum ion exchange mini columns. Rat brain total protein extracts (3 ml) were loaded onto an Aurum AEX or CEX mini column, then eluted using the recommended protocol. The fractionated samples were treated with the ReadyPrep reduction/alkylation and 2-D cleanup kits prior to 2-D gel analysis. Left, total rat brain protein; center, sample that bound to the Aurum AEX column (acidic proteins); right, sample that bound to the Aurum CEX column (basic proteins).

Aurum ion exchange mini kits utilize ion exchange chromatography to selectively enrich either acidic or basic proteins in less than 30 minutes. These easy-to-use kits include the columns and buffers for cation exchange (CEX) or anion exchange (AEX) chromatography and can be used with a variety of starting samples. Isolated proteins are suitable for most downstream proteomic applications, including 2-D gel analysis and mass spectrometry.

Aurum ion exchange mini kits:

  • Use a patented* polymerization technology to achieve ultrahigh protein binding capacity
  • Accommodate up to 1 ml of sample
  • Use a quick, easy, spin-column format
  • Work on a variety of sample sources (serum, plasma, mammalian tissues or cells, plant leaves, E. coli, yeast)

*U.S. patent 6,423,666.
