Einfluß von Ionenstärke und pH auf die differentielle Dekondensation der Nukleoproteide isolierter Speicheldrüsen-Zellkerne und -Chromosomen von Chironomus thummi

Abstract

A new method of isolating nuclei and chromosomes of salivary gland cells is described. — The influence of ionic strength and pH of the medium on the state of decondensation of chromosomal bands is studied. In the isolation medium (a modified Ringer solution), all the bands are in a condensed state; as the ionic strength is increased the bands decondense… (More)
