DNA Molecules Used To Assemble Nanoparticles

...ifferent cells, it would be 25 synthesis steps the traditional way," Baker said. At two to three months per synthesis, and a significant loss of yield for each step, that approach just wouldn't be practical. Instead, the Baker group will create a library of single-functional dendrimers that can be synthesized i...

...contained in a cartridge similar to those used for traditional dialysis. With dialysis, a patient's blood runs through the fibers and a solution with the normal composition of electrolytes runs on the outside. Through osmosis, waste products in the blood migrate across the fibers into the solution. The now-dirt...

Scientists identify new model Of NK cell development

...rculating blood. In other words, they had a hunch traditional thinking about the origin of human NK cells might be wrong. In building a case to support their beliefs, they first identified the NK precursor cell, then, they measured the number of the precursors in different parts of the body. Through flow cytom...

Influenza vaccine uses insect cells to speed development
