Preparation and Characterization of Glycosaminoglycan Chemokine Coreceptors.

abstract：:Electrochemical microsensors for O2, pH, H2S, H2, and N2O are now available commercially, thus it has become a relatively simple task to analyze the microenvironment in stratified microbial communities for several chemical species. In addition, sensors are available for the physical parameters diffusivity and flow, an...
