Project: Biophysical investigation of purified HTT protein samples

Experiment: Large-scale stringent purification of Q23 HTT and HTT-HAP40 using heparin affinity chromatography

Date completed: 2019/05/22

Rationale: Previous attempts to generate a much purer and homogenous HTT-HAP40 sample showed that the complex can bind heparin resin. In small-scale experiment, I also incorporated helpful suggestions from scientists at the CHDI Palm Springs meeting full-length HTT research breakout group i.e. ATP wash to remove HSP proteins. The experiment included 3 affinity chromatography steps with FLAG, heparin and NiNTA resin and finally a gel filtration step and yielded a highly pure HTT-HAP40 sample: https://zenodo.org/record/3234174.I now want to try this purification with apo HTT.
