title: Perichromatin granules in the liver nuclei after isolation of hnRNP (informofer) particles.
abstract: The influence of the extraction of hnRNP (informofer) particles on the ultrastructural appearance of the perichromatin granules was studied. The extraction of hnRNP particles was carried out by SAMARINA's procedure from the rat liver nuclear fraction. The extraction did not change the numbers and the general ultrastructural features of perichromatin granules. It is therefore unlikely that the perichromatin granules are the morphological representatives of storaged or transported hnRNA.
