Rapidly developing sequencing technologies have provided the possibility for identification of a DNA nucleotide sequence of a whole individual human genome just in a couple of weeks. Working capacity of some sequencers is already measured in thousands of milliards of base pairs per an operating cycl...

This study shows that Yersinia pestis capsular antigen F1 conjugated to the CS nano-particles demonstrates apparent immunogenic effects. When injected to the test animals it was able to stimulate the production of specific antibodies under smaller antigenic load, it caused activation of the genetic...
