WitrynaWe used polytene immunofluorescence to investigate the low-resolution global and local distribution of Spt5 and Spt6 and crosslinking and immunoprecipitation with specific antibodies to address the high-resolution localization of Spt5 and Spt6 under non–heat shock and heat shock conditions. ... One possible explanation for this Spt5 ... WitrynaImmunofluorescence assays use antibody-fluorogen conjugates to illuminate antigens for easy, rapid detection. Direct immunofluorescence can be used to detect the presence of bacteria in clinical samples such as sputum. Indirect immunofluorescence detects the presence of antigen-specific antibodies in patient sera. The fluorescent …
