Abstract: Let $ f:{\Sigma ^\infty }X \to {\Sigma ^\infty }Y$ be a stable map between two connected spaces, and let $ {E_{\ast}}$ be a generalized homology theory. We show that if $ {E_{\ast}}(f)$ is an isomorphism then $ {E_{\ast}}({\Omega ^\infty }f):{E_{\ast}}(QX) \to {E_{\ast}}(QY)$ is a monomorphism, but possibly not an epimorphism. Applications of this theorem include results of Miller and Snaith concerning the $ K$-theory of the Kahn-Priddy map.
