The use of fluorochromes and flow cytometry is a good tool for monitoring many markers of sperm function although the capacitation and acrosome reaction processes have been studied for many years, being that these processes are so complex, there is still much information to be elucidated.
Therefore, flow cytometry is the current technical solution for rapid, precisely reproducible assessment of cell suspensions including sperm samples one of the most used fluorochrome combinations for simultaneous evaluation of plasma membrane integrity (ie, viability) and acrosome integrity are fluorescein isothiocyanate-conjugated pea.
