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