Abstract
A short proof of the technical theorem underlying G. G. Kasparov's KK-theory is presented. The theorem is concerned with the separation of two orthogonal subalgebras of an "outer multiplier algebra" M(D) D by an element in a relative commutant. The proof given here is a simple application of the notion of quasicentral approximate unit.
