expression of His-tagged fusion proteins encompassing Der p 2 with either mature or proDer p 1 in Escherichia coli strain BL21 (DE3) and Origami2 (DE3), or in Pichia pastoris strain GS115 or X33. Four fusion proteins are expressed in Escherichia coli as inclusion bodies, whereas only chimeras comprising proDer p 1 are obtained in yeast
