• Requires specific elution conditions
• Concentrating effect
• Diffusion – no binding
• Any elution conditions
• Diluting effect

There are many ways to improve protein purity and yield
• Sample conditions
• Optimize binding conditions
• Optimize elution conditions
• Multi-step purificationNo imidazole in the binding buffer Imidazole in the binding buffer
