Synthesis of Zwitterionic Polymers Containing a Tertiary Sulfonium Group for Protein Stabilization.

abstract：:Glycogen is mainly found as the principal storage form of glucose in cells. Many bacteria are able to synthesize large amounts of glycogen under unfavorable life conditions. By combining infrared spectroscopy, single molecule force spectroscopy (SMFS) and immuno-staining technique, we evidenced that planktonic P. flu...
