Also known as Colleen’s nemesis, this handy instrument known as the A50-Micro handles all of our microparticle-based analyses.  For a decade, I’ve always known that flow is the ONLY way to analyze microparticles/apoptotic blebs/microvesicles etc.  I would never use DLS or non-flow cell based instruments to do what this little guy does.  Ours has three lasers and about 7 different filter sets.  We can do 4 different biomarkers although we’d never be that crazy to – three is enough!  We’re looking forward to getting our second instrument although I’m seriously considering the Attune flow cytometer just to compare!  But yes, this instrument is amazing.
