WebAug 26, 2024 · To ascertain whether the bulky GFP tag affects the stability of the SpCENP-A protein, we fused a smaller FLAG-tag to SpCENP-A, and expressed the constructs in WT cells. Similar to the FL SpCENP-A-GFP ( Figure 2 A), as the protein level decreased, there was an increase in turnover of the FL SpCENP-A-FLAG proteins, and this was … WebArguably the simplest affinity tag is the polyhistidine (His) tag. Small and unlikely to affect function, His-tagged proteins can be purified using metal-affinity chromatography, usually using a Ni2+ column. Like other affinity … WebThe Flag®-tag can be used for the purification of any recombinant protein fused to the Flag®-tag, using agarose resins or magnetic beads that are coupled to an anti-Flag® antibody. Even though high protein yields cannot be achieved with the Flag®-tag, it is mostly recommended to use the Flag® for membrane protein purification. greenbelly ultralight backpacking
