Figure 5From: Intracellular delivery of peptides via association with ubiquitin or SUMO-1 coupled to protein transduction domainsActivated lymphocytes were incubated for 2 h with 1 μM of SHPR190 labelled with Alexa 488. Cells were then washed and maintained in HBS buffer for examination by confocal microscopy. Visualisation was performed either by fluorescence (top panel) or by light transmission (bottom panel).Back to article page
