Other more commonly used tags such as S-tag, histidine and haemagglutinin require harsher or denaturing conditions for elution from beads (for review see [15, 16]). This is disadvantageous for downstream biochemical analyses.

WebElution Buffer Recovery of Antigen: Add 100 µl of Elution Buffer to the tube. Incubate the tube at room temperature with mixing for 5 minutes. Magnetically separate the beads and save the supernatant containing target antigen. Note: If a low pH elution buffer is selected for elution, streptavidin leaching might occur. WebBiotin/streptavidin has an ultra‐strong affinity and is one of the few cases where extensive washing, using SDS, with the goal of lowering background is possible. For biotin based pulldowns we elute by digesting proteins off the beads. Elution by digestion is better than 90% for the proteins that
