[Creatine kinase BB with atypical migration. Possible role of IgA in its formation]. / Etude d'une créatine-kinase BB de migration atypique. Rôle éventuel des IgA dans sa formation.

ABSTRACT

We studied the behaviour of an atypical CK in one female patient. Using exclusion-diffusion chromatography of the serum, on Sephadex G 200, we observed the simultaneous elution of a CK-BB and IgA. We demonstrated that this eluate contained the components responsible for this atypical CK. The study of the behaviour of this enzyme complex reveals a resemblance with that of immune complexes.
