Purification of HTT N-HEAT_81-1643

The purification of huntingtin (HTT) fragments is a useful approach to learn more about the function of HTT in the cell. By obtaining soluble and monomeric samples of HTT domains namely the C-HEAT, N-HEAT and bridge domains, specific protein-protein interactions can be studied. Furthermore, domains of HTT in soluble monomeric form could enable crystallization studies.  

The first expression and purification of these fragments can be found on these posts https://zenodo.org/record/2600051#.XKU89aeZPOQ and https://zenodo.org/record/2628060#.XULMtnspDb0 (performed by Dr. Rachel Harding). The latest post shows the purification of construct the HTT N-HEAT_81-1643 domain which elutes from Superdex 200 10/300 GL column in the void volume. The results here presented are a follow up of that purification.
