a bacterial expression vector containing a segment of the v-abl gene from abelson murine leukemia virus ( a-mulv ) was constructed such that the gag region of v-abl was replaced by a sequence encoding the igg-binding domain of the s. aureus protein a. pabl hp , a fusion protein encoded by this vector was rapidly purified to near homogeneity by affinity chromatography on igg-affigel and mono q fplc .
