Quantification of Interbacterial Competition using Single-Cell Fluorescence Imaging
نویسندگان
چکیده
Interbacterial competition can directly impact the structure and function of microbiomes. This work describes a fluorescence microscopy approach that be used to visualize quantify competitive interactions between different bacterial strains at single-cell level. The protocol described here provides methods for advanced approaches in slide preparation on both upright inverted epifluorescence microscopes, live-cell time-lapse imaging techniques, quantitative image analysis using open-source software FIJI. this manuscript outlines quantification symbiotic Vibrio fischeri populations by measuring change area over time two coincubated are expressing fluorescent proteins from stable plasmids. Alternative optimizing model systems require growth conditions. Although assay uses conditions optimized V. fischeri, is highly reproducible easily adapted study among culturable isolates diverse

Live-cell Imaging Using Fluorescence Microscopy
The ever increasing abundance of different fluorescent proteins and vital dyes that are available to researchers today make it possible to study a large variety of dynamic biological processes in live-cells [1, 2]. Many proteins of interest can be studied by expressing fluorescent fusion proteins in cells, either transiently by transfection or viral infection or permanently using transgenic ani...
متن کاملNeural Imaging Using Single-Photon Avalanche Diodes
Introduction: This paper analyses the ability of single-photon avalanche diodes (SPADs) for neural imaging. The current trend in the production of SPADs moves toward the minimumdark count rate (DCR) and maximum photon detection probability (PDP). Moreover, the jitter response which is the main measurement characteristic for the timing uncertainty is progressing. Methods: The neural imaging pro...
متن کاملEmerging in vivo analyses of cell function using fluorescence imaging (*).
Understanding how cells of all types sense external and internal signals and how these signals are processed to yield particular responses is a major goal of biology. Genetically encoded fluorescent proteins (FPs) and fluorescent sensors are playing an important role in achieving this comprehensive knowledge base of cell function. Providing high sensitivity and immense versatility while being m...
متن کاملQuantification of integrin receptor agonism by fluorescence lifetime imaging.
Both spatiotemporal analyses of adhesion signalling and the development of pharmacological inhibitors of integrin receptors currently suffer from the lack of an assay to measure integrin-effector binding and the response of these interactions to antagonists. Indeed, anti-integrin compounds have failed in the clinic because of secondary side effects resulting from agonistic activity. Here, we ha...
