Trusted product bands including Alexa Fluor, SYTOX and Click-iT empower scientists working in cell biology, genetic analysis, protein biology, and cell engineering to make the discoveries that advance our understanding today and catalyze the research goals of tomorrow. was observed by confocal microscopy. Hoechst (Thermo Fisher, H3570) and propidium iodide (Thermo Fisher, P3566) at a volume of 1 l each were added to the final cell suspension to identify live and dead cells, respectively. The same confocal settings were used in b. Distinct brain regions differentially and rapidly tailor the leukocyte landscape during psychological stress, calibrating the ability of the immune system to respond to physical threats. The biocompatibility of the gels was evaluated by fluorescein diacetate (FDA)/propidium iodide (PI) staining, immunofluorescence staining of biomarkers, and Cell Counting Kit-8 (CCK8) assay of human umbilical vein endothelial cells (HUVECs) and vascular smooth muscle cells (VSMCs), which are the main cell components of blood vessels. Optical sections taken through propidium iodide (PI) stained spheres revealed that mammospheres are compact cellular structures (Fig. However, the mechanisms controlling bleeding and mucosal haemostasis remain elusive. z -Stacks were collected at 0.5 m z -intervals for the entire stack at 63 magnification. EdU assay A laser confocal microscope (SP 8, Leica) was used for image acquisition. LDH activity LDH activity was observed by confocal microscopy. The qPCR protocol was performed for 40 cycles and each cycle consisted of denaturation at 95 C for 15 s, annealing at 60 C for 1 min, and extension at 72 C for 1 min. Vybrant DiD-labeled YT (magenta) cells were co-cultured with EV HeLa in SYTOX green containing medium. PI is widely used in fluorescence microscopy, confocal laser scanning microscopy, flow cytometry, and fluorometry.

The Cell Health Assay is a fluorescence-based assay used for live/dead cell counting that is amenable to fluorescence microscopy and flow cytometry analyses wherein live cells are detected by the conversion of calcein-AM to calcein and dead cells by uptake of propidium iodide. A key event of vertebrate fertilization is the membrane fusion of the gametes, enabling the spermatozoon to enter the ooplasm and trigger the resumption of meiosis ().Molecular recognition between the plasma membranes in the mouse involves the egg receptor on the sperm, Izumo1, a member of the immunoglobulin (Ig) superfamily, and the sperm receptor on the egg, The original propidium iodide staining dataset was resampled to 10 m 3. 1 hour later, cells were imaged by time-lapse confocal microscopy for 160 min.
