During the purification, strong association between the intein segments effectively captures the tagged target onto the capture resin while simultaneously generating a cleaving-competent intein complex.

Inteins - Current Biology

WebThe mini-intein (Mxe GyrA intein) in pTXB1 has been used to purify a wide range of target protein fusions. Cloning into the NdeI and the SapI sites results in the fusion of the intein to the C-terminus of the target protein, without any extra amino acids on the target protein after cleavage of the intein tag. 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. highgene abclonal
