WebCleavage is a word for a kind of splitting or separation: it's mainly used for the split between a woman's breasts. WebThe secreted fusion proteins were purified from culture medium by binding to chitin beads and subjected to reaction conditions to induce intein self-cleavage to release the target protein. The M6 and NucA fusion proteins were shown to bind chitin beads and elute under cleavage reaction conditions. WebIntein cleavage is used to release the target protein after purification of the fusion protein (Fig. 9.19).
