Engaged in the study of human transporters; Serotonin transporter (SERT), Glucose transporter 1 (GLUT1) and Gluccose-6-phosphate transporter (G6PT). Using Pichia pastoris as the recombinant expression host, utilising amphipathic co-polymers DIBMA (diisobutylene maleic acid) and SMA (styrene maleic acid) for detergent-free purification. Benefiting from the preservation of associated membrane lipids and increased thermostability, which help retain protein function vital for downstream functional assays and biophysical techniques.
