Nuclear envelope permeability

Nature. 1975 Mar 13;254(5496):109-14. doi: 10.1038/254109a0.

Abstract

The permeability of the amphibian oocyte nuclear envelope in situ has been determined for three tritiated dextrans. The envelope is a sieve, restricting molecular movement between the cytoplasm and nucleus. The patent radius of its pores is about 45å.
