Neurophysin molecular weights

In this and other respects e.g histidine was absent, it was different from the so-called van Dyke protein. We decided to call the major sub-fraction neurophysin-M until more was known about it and a better name could be found. Neurophysin-M behaved as a homogeneous protein in the ultracentrifuge and assuming a partial specific volume of 0.7 9 ml. per g. a molecular weight of 23 000 was calculated. During the course of the work we began to study the electrophoretic behaviour of the proteins in the buffer devised by Ferguson and Wallace In this system neurophysin-M...
