Make and purify a protein

Produce a recombinant protein, purify it and check that what you have is pure, folded and not aggregated.

  1. Choose a host and conditions that give soluble protein.

  2. Pull the tagged protein out of the lysate in a single step.

  3. Remove the remaining contaminants and aggregates by size or charge.

  4. SDS-PAGENot started

    Check purity on a gel.

  5. Check the protein is folded and find the buffer that keeps it most stable.

  6. Confirm it is not aggregated before you use it.
