WebCommon choices for protein affinity tags are polyhistidine (histidine-tag), glutathione S-transferase (GST), maltose-binding protein (MBP), Strep -tag® II, and FLAG™ tags. His … WebThe FLAG, hemaglutinin antigen (HA), and c-myc tags have been the workhorses of the affinity tag world for years, and deciding on which one to use will depend on your application (see table below). The antibodies available for these tags really are good and can be used for western blots, IP, and affinity purification.
WebFLAG is an affinity tag widely used for rapid and highly specific one-step protein purification. Native elution of protein from anti-FLAG antibody resins allows the identification of protein and nucleic acid binding partners and functional analysis using biochemical activity assays. 1.
