    摘要: The invention relates to an expression construct for the soluble expression of polypeptides in host cells and for the expression of polypeptides on the surface of host cells, using alternative splicing. The amount of cell membrane expression of polypeptides such as antibodies, antibody fragments and bispecific antibodies can be correlated directly to the amount of soluble polypeptide expressed. In the case of bispecific antibodies, cell membrane expression of heterodimer and homodimer products can be correlated directly to the soluble expression of these products, thereby aiding selection of a desired producer clone.
