CHIMERIC ACCEPTOR BY DNA SPLICING AND DEVELOPMENT

摘要

Chimeric multi-subunit receptors are provided involving a binding region resulting from the organization of two subunit chains and a non-binding region which may have physiological significance. Particularly, chimeric immunoglobulins are provided having variable regions from one species and constant regions from another species, by linking DNA sequences encoding for the variable regions of the light and heavy chains from one species to the constant regions of the light and heavy chains respectively from a different species. Introduction of the resulting genes into mammalian host cells under conditions for expressions provides for production of chimeric immunoglobulins having the specificity of the variable region derived from a first species and the physiological functions of the constant region from a different species.
