From: Retro-protein XXA is a remarkable solubilizing fusion tag for inclusion bodies
XXA exhibited its solubilizing effect at both high and low temperatures. a Most sumo-NbALFA fusion proteins were expressed in an insoluble form at 16 °C. b The NbALFA was expressed as soluble at 16 °C after fusion with XXA. c Most MBP-CUA63106 fusion proteins were expressed as insoluble at 25 °C. d The CUA63106 was expressed as soluble at 25 °C after fusion with XXA.
