Micro-spin column (no filter) for enrichment of antibody samples
Protein A • Protein G 

• Significantly reduce time and expense of SPE (e.g., can top-load samples and centrifuge)
• Protein A/G technologies deliver high-yield purification of IgG from small samples of serum and other fluids
• Micro-spin column allows precise control over rates of binding and elution
• No filters, glues, polymers, or matrices: reducing sample loss and contamination risk

Antibody Enrichment TopTip micro-spin column enables selective Protein A and Protein G affinity reactions in a convenient micro-spin column.

The fine slit at the bottom of the TopTip (slit width: 1-2 µm) permits liquid to pass through (with pressure via centrifuge or syringe), but retains media in the tip. This eliminates need for a filter – reducing dead volume, loss of sample and contamination risk.

How TopTip works

Media selection

Protein A and Protein G differ in their ability to bind antibodies of different species and subclasses. Media selection is based on these known affinities.
