Affinity-Tagged Purification
Before you can analyze your recombinant protein of interest, you’ll need to purify it from your expression medium and other macromolecules. Affinity tags are one of the main strategies used to purify proteins and antibodies, and there are many tag systems to choose from. Check out these resources to help you choose the best affinity tag for your project.
Protein Purification
When it comes time to isolate and purify your protein of interest, affinity tagging offers flexibility and selectivity. But identifying the best system for tagging your protein will take a bit of leg work. Find inspiration with these resources.
