MagStrep "type3" XT beads - high specificity - low background

 

Purification of GFP-Strep-tag fusion protein from crude bact. extract using MagStrep “type3” XT beads

Due to specific binding properties of the beads even the elution by boiling leads to highly pure proteins (GFP peak at ~28kDa ignoring Strep-Tactin XT peak).
(Protein purification analysis was performed with an Agilent Bioanalyzer 2100 system instead of SDS-PAGE)
