In contrast to most eukaryotic cells, mature sperm cells largely use protamines to package their genomic DNA, most likely to achieve an even higher packaging ratio.

Following graduation in 1943, he undertook an 18-month residency at Carl and Gerty Cori, working on the interaction of protamine with rabbit muscle phosphorylase.

Sperm analysis of infertile men shows that some infertile men retain an increased level of histones in their mature sperm and lower levels of protamines . [ 3]

During the last years of Kossel's life, he conducted important research into the composition of the protein types protamines and histones, and discovered flavianic acid.

A disadvantage recognised early was the absence of an antidote in case acute bleeding develops, while warfarin can be antagonised by vitamin K and heparin by protamine sulfate.

Avoiding rapid infusion of protamine sulfate and pre-treating at-risk patients with histamine receptor antagonists ( H1 and H2 ) and steroids may minimize these reactions.
37.
The insulin aspart protamine portion is a crystalline form of insulin aspart, which delays the action of the insulin, giving it a prolonged absorption profile after injection.

The host s immune system will release protamines and other antimicrobials to combat the infection, but OmpT easily degrades the cationic protamine peptides, thus enhancing the risk of infection.

Looking at the counterpart genes in other primates, the Chicago biologists calculated that the protamine genes of chimpanzees had evolved just as fast, but those of gorillas much more slowly.
