Abstract:

Various embodiments disclosed herein comprise acoustic cytometry based methods, kits, computer software methods and systems to analyze a variety of bioparticles. In one embodiment, a method for analyzing bioparticles comprises: acoustically focusing one or more bioparticles through an interrogation zone; optically exciting the one or more bioparticles in the interrogation zone with an excitation source; detecting an optical signal from the bioparticles; and analyzing the optical signal to characterize at least one quality or quantity parameter of the bioparticles. Properties of biomolecules that may be analyzed include but are not limited to cell proliferation analysis, live/dead cell discrimination, cell cycle analysis, basic phenotyping, immunophenotyping, rare-event detection, apoptosis, phagocytosis, pinocytosis, detection of phosphoproteins, detection of one or more cellular markers, detection of one or more intracellular marker, detection of cancer cells, detection of pathological markers on a cell, microbial cell analysis and/or picophytoplankton analysis.
