Biotium | MitoView™ 633 offers advantages over TMRM as a probe for mitochondrial membrane potential
Mitochondria are essential for maintaining cellular health, with a key aspect of mitochondrial function being the mitochondrial membrane potential (mitochondrial potential). Mitochondrial potential is a valuable biomarker for detecting any disruptions linked to mitochondrial dysfunction. This is because it reflects the electrical gradient central to processes like ATP synthesis and calcium homeostasis across the inner […]

Biotium | Bright and photostable CF® Dyes help validate fluorescence lifetime separation in multi-colour imaging
Fluorescence lifetime imaging microscopy (FLIM) has emerged as a powerful technique for multi-colour imaging, allowing researchers to distinguish fluorochromes beyond traditional spectral separation methods. By leveraging fluorescence lifetime differences, FLIM provides additional fluorochrome discrimination, enabling more complex imaging experiments with fewer spectral constraints. This approach is particularly valuable in confocal and Stimulated Emission Depletion (STED) […]

Biotium | Tech Tip:Using ViaFluor® SE Stains for Cell Tracing and Co-Culture
ViaFluor® SE Cell Proliferation Kits ORDER HERE CellBrite® Cytoplasmic Membrane Dyes ORDER HERE ViaFluor® SE Cell Proliferation Kits use amine-reactive dyes to covalently label cells throughout the cytoplasm and intracellular compartments. ViaFluor® SE dyes are initially membrane-permeable and non-fluorescent. After the compound enters viable cells, it is hydrolyzed by cytoplasmic esterases to releases the […]

Biotium | Bring Out Your Dead: v-PCR for Microbial Population and Diversity Studies
Understanding microbes and their ecology is crucial for modern medicine and functioning society. Microbes cause disease, but are also vital components of a healthy gut and skin microbiome. Microbes fix nitrogen for plants, produce oxygen in marine environments, facilitate rusting and infrastructure breakdown, and come with us to space. By better understanding microbial diversity and […]

Biotium | Switching from agar plates to v-PCR for bacteria viability testing – What you need to know
The problem with plating Counting the number of living bacteria in a sample is a common enough task: maybe you are comparing bacteria populations in different rivers, or perhaps you want to know whether your disinfection method works. Your first thought is probably to prepare serial dilutions of a liquid culture, plate them out on […]
