Subcellular localization of natural /sup 210/Po in the hepatopancreas of the rock lobster (Jasus lalandii)

Abstract

The subcellular localization of the naturally occurring nuclide /sup 210/Po in the hepatopancreas of the South African rock lobster, Jasus lalandii, has been studied using centrifugation, ultrafiltration and chromatography. Just over half of the /sup 210/Po was found to be associated with a component in the microsomal pellet. Most of the /sup 210/Po was tightly bound to a component of high molecular mass. Dissociation of the /sup 210/Po from this component required incubation with sulphydryl-reducing reagents, after which the /sup 210/Po appeared to associate with a fraction having a molecular mass of 1500 daltons or less. A search for negatively-charged, hydrophobic, sulphur-containing membrane proteins which bind /sup 210/Po is suggested.
