We review the role of the universal Isgur-Wise functions parameterizing the
$B$ meson semileptonic matrix elements to charm states in the infinite heavy
quark mass limit. We also discuss the determination of one of such form factors
by QCD sum rules in the framework of the Heavy Quark Effective Theory.
