Application
Abberior® STAR 440SXP has been conjugated with secondary anti-mouse antibody for dual colour STED (stimulated emission depletion) microscopy.[1] Again, it has been labelled with secondary antibody for STED microscopy in primary hippocampal cells prepared from E18 Sprague Dawley embryos.[2]
Designed and tested for fluorescent super-resolution microscopy
