WebThe advent of fluorescent staining improved microscopical evaluation of sperm, however, one of the major drawbacks remains, that is that one can only evaluate 100 or 200 sperm per sample. The advent of flow cytometry in the early 1970's and the development of new stains has led to more accurate means of assessing sperm viability. ranger build and priceWebThese fluorescent-based LIVE/DEAD assays can be used to evaluate viability in cellular populations, bacteria, fungi, and yeast. The fluorescent dyes used in these viability assays range from blue to near-IR emission. Some viability assays permit fixation, which enables intracellular staining and neutralization of pathogens. ranger by polarisWebBull sperm mitochondria are incubated with a vital, fixable, mitochondrion-specific fluorescent probe MitoTracker Green FM. The labeled spermatozoa can be fixed, permeabilized, and immunostained without loss of MitoTracker labeling, as MitoTracker dyes are incorporated mainly into the detergent-resistant mitochondrial membranes. owens corning roof color pacific waveWebHuman sperm populations were exposed to a hypo-osmotic medium for 60 minutes, and then incubated in a 1 microg/mL solution of the fluorescent dye Hoescht 33258 (H33258) for 10 minutes.
