Introduction
Magnetic IMAC (immobilised metal affinity chromatography) resin is typically useful in purifying small quantity low concentration histidine-tagged proteins. For example, when 10 – 50 µl of resin is required for protein purification, it is difficult to handle such small quantity in columns. Magnetic IMAC resins can be easily processed in aid of a magnet. The liquid / solid separation required in each purification step (e.g. equilibration, binding, washing and elution) is readily achieved in aid of a magnet (e.g. magnetic stirring bar).
Key benefits:
- Tailored base matrix design for batch magnetic purification of proteins
- High binding capacity (could be over 40 mg/ml)
- Simple and convenient operation, no any chromatography training required
- Flexible operational conditions
- Inexpensive, as the cost is similar to non-magnetic IMAC resins
- No special magnet required. A magnetic stirring bar commonly available in laboratories can be used to drag down the magnetic IMAC particles when the resin volume is small
- A choice of four types of immobilised metal ions available
- Very low metal leakage
- Full operation manual (including purification conditions) supplied
