Experiment: Optimisation of HTT-HAP40 purification using heparin affinity chromatography

Rationale: The current protocol for HTT and HTT-HAP40 purification I am using requires a long incubation of clarified cell lysate with FLAG resin. To potentially improve yields and sample quality, it would perhaps be beneficial to have a quick heparin resin purification step prior to FLAG binding which may also remove contaminating nucleic acid material. To test this hypothesis, small-scale purification of Q23 HTT-HAP40 samples in different buffer systems were conducted using heparin and FLAG affinity chromatography which showed the sample bound heparin resin – see https://zenodo.org/record/2553669. Now this need to be scaled up and tested more stringently.
