[Production and some properties of covalent conjugates of total histone and kanamycin]
Abstract:
A complex containing total histone and antibiotic kanamycin was produced under optimal conditions using glutaric aldehyde. The obtained water-soluble covalently bound conjugates of these substances were identified by means of enzyme labelled immunoassay and their molecular mass estimated. The validity of new class of highly effective drugs, which may be produced basing on the principles studied, was substantiated considering that histones exhibit the transport properties and are able to augment hematoencephalic barrier permeability.

The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...
