In veel biologische en klinische situaties is het voordelig om cellulaire processen te bestuderen als ze zich ontwikkelen in hun eigen micro-omgeving. Hier beschrijven we de montage en het gebruik van een low-cost fiber-optische microscoop, die real-time beeldvorming kan bieden in celkweek, dierproeven en klinische studies de patiënt.

Hoge-resolutie Fiber-optic Microendoscopy voor In situ Cellular Imaging

Spatiotemporele informatie over dynamische eiwitten in levende cellen is cruciaal voor het begrijpen van de biologie. Een type superresolutiemicroscopie genaamd fast 3D-structured illumination microscopy (f3D-SIM) onthult unieke informatie over de cytokinetische Z-ring in bacteriën: zowel het kralenachtige uiterlijk als de snelle dynamica van FtsZ binnen de ring.

Super-resolution Imaging van de Cytokinetic Z Ring in levende bacteriën met behulp van Fast-3D Structured Illumination Microscopy (F3D-SIM)

Hier presenteren we een praktische gids voor het bouwen van een geïntegreerde microscopie-systeem, dat wordt samengevoegd conventionele epi-belichting fluorescerende imaging, single-molecuul detectie gebaseerde Super resolutie beeldvorming en Multi-Color single-molecuul detectie, met inbegrip van single-molecuul fluorescentie resonantie energieoverdracht imaging, in één set-up op een kostenefficiënte manier.

Uitvoeren van meerdere Imaging modi met één fluorescentie Microscoop

Nanoschaal beeldvorming van klinische weefselmonsters kan het begrip van ziekte pathogenese verbeteren. Expansie pathologie (ExPath) is een versie van expansie microscopie (ExM), aangepast voor compatibiliteit met standaard klinische weefselmonsters, om de nanoschaal configuratie van biomoleules te verkennen met conventionele diffractie beperkte microscopen.

Nanoscopische beeldvorming van menselijke weefsel secties via fysische en isotrope expansie

De gepresenteerde methode maakt visualisatie van fluorescerend gelabelde cellulaire eiwitten met expansiemicroscopie mogelijk, wat leidt tot een resolutie van 70 nm op een conventionele microscoop.

Beeldvorming van Podocytische eiwitten Nephrin, Actine en Podocine met expansiemicroscopie

Hier wordt een protocol gepresenteerd voor de implementatie van expansiemicroscopie in vroege Drosophila-embryo's om beeldvorming met superresolutie te bereiken met behulp van een conventionele confocale microscoop met laserscanning.

Expansiemicroscopie gebruiken om Drosophila-embryo's in het geheel fysiek te vergroten voor beeldvorming met superresolutie

Hier wordt een nieuwe versie van expansiemicroscopie (ExM) gepresenteerd, Magnify, die is aangepast voor maximaal 11-voudige expansie, met behoud van een uitgebreide reeks biomolecuulklassen en compatibel is met een breed scala aan weefseltypen. Het maakt de ondervraging van de nanoschaalconfiguratie van biomoleculen mogelijk met behulp van conventionele diffractie-beperkte microscopen.

Universele moleculaire retentie met 11-voudige expansiemicroscopie

Deze studie toont een gedetailleerd protocol voor het uitvoeren van ultrastructuurexpansiemicroscopie in drie in vitro levenscyclusstadia van Trypanosoma cruzi, de ziekteverwekker die verantwoordelijk is voor de ziekte van Chagas. We nemen de geoptimaliseerde techniek voor cytoskeletale eiwitten en pan-proteoomlabeling op.

Hier stellen we een eenvoudig protocol voor dat metabole oligosacharide-engineering, klikchemie en expansiemicroscopie combineert en dat bioimaging van intracellulaire gesialyleerde N-glycoproteïnen met verbeterde resolutie mogelijk maakt met behulp van routinematige microscopieapparatuur.

Visualisatie van intracellulaire sialylering met klikchemie en expansiemicroscopie

Dit protocol beschrijft de geavanceerde beeldvormingstoepassingen en het beheer van gedeelde middelen van een laser-scannend confocaal microscoopsysteem, geïntegreerd met een multiplexed arraydetector voor hoogresolutie cellulaire en subcellulaire beeldvorming. De workflow maakt multimodale beeldvorming mogelijk van confocaal tot superresolutie (~120 nm) binnen één platform, waardoor visualisatie op nanoschaal toegankelijker wordt.

Leer expansiemicroscopie met cryofixatie voor hoogresolutiebeeldvorming van cellulaire structuren. Deze methode behoudt de natuurlijke structuur van organellen en microtubuli voor superresolutie met standaard microscopen.
