Persistence of bovine papillomavirus (pBPV-1) as an extrachromosomal element in tissues of microinjected Xenopus laevis

Abstract

In the present study we have analyzed the persistence and distribution of injected pBPV vectors in the organs of the frog, Xenopus laevis that have reached post-metamorphic stages. BPV DNA (250 pg) was injected into the cytoplasm of fertilized Xenopus eggs between 45—75 minute following fertilization (Figure 1). DNA was extracted from embryos and tissues of… (More)
