For two free base corroles with different architecture of peripheral substitution, the solvatochromic shifts absorption bands in a series solvents nature are herein determined, and effects is analyzed by Valentine method. It found that solvatochromism bases originates due to universal nonspecific interactions, short-wavelength T2 tautomer experiences stronger solvation. shown polar aprotic (ace...

To develop a rapid phenotypic assay, recombinant PVL F component was used to generate monoclonal antibodies by phage display. These antibodies were spotted on protein microarrays and screened using different lukF-PV preparations an...
