Universal Diagnostic Assay for Detection and Identification of Poxviruses in Clinical Samples
CDC researchers have developed an assay for detection and diagnosis of poxviruses within clinical samples or from lab culture-systems. The assay specifically targets chordopoxviruses (except avipoxviruses) for PCR-based identification; an improvement upon the current standard of cell culturing methodologies. Individual chordopoxvirus species can cause...

Chemo-Enzymatic Site-Specific Photocaging of Peptides and Proteins
INV-17072 Background Photocaging is a process in which a molecule is covalently modified by a photolabile group; the molecule is often referred to as being ‘caged.’ Typically. caging renders the molecule non-functional. Subsequently, photolysis of such ‘caged’ peptides and proteins removes the photolabile group and regenerates...
