Teil 1: Bereiten Nematoden Nährmedien (NGM)-Platten Dieser Abschnitt beschreibt die Herstellung der festen NGM-Platten für den Einsatz in der Lebensdauer zu experimentieren. Eine grundlegende Lebensdauer Experiment erfordert zwei Arten von Platten: Standard NGM-Platten, die keine Zusatzstoffe und Amp / FUDR Platten, die sowohl Ampicillin (Amp) und Fluordeoxyuridin (FUDR) hinzugefügt, um die NGM haben enthalten. Ampicillin wird verwendet, um ausländische bakterielle Kontamination zu vermeid...

measuring caenorhabditis elegans life span on solid media

Altern ist ein degenerativer Prozess durch eine progressive Verschlechterung der zellulären Bestandteile und Organellen aufgrund der Mortalität gekennzeichnet. Der Fadenwurm<em&gt; Caenorhabditis elegans</em&gt; Hat als Haupt-Modell verwendet, um die Biologie des Alterns Studie hervor. Da nahezu alle biologischen Subsystem erfährt funktionelle Rückgang mit zunehmendem Alter, das Leben ist span den primären Endpunkt von Interesse, wenn man Gesamtrate des Alterns. In Nematoden, ist Lebensdauer in der Regel als die Anzahl der Tage ein Tier reagiert weiterhin auf äußere Reize definiert. Nematoden können entweder propagierten in flüssigen Medien oder auf festen Medien in Platten, und Techniken zur Messung der Lebensdauer unter beiden Bedingungen entwickelt worden. Hier präsentieren wir eine allgemeine Verfahren zur Messung der Lebensdauer von Nematoden auf einem soliden Wachstum Nematoden Medien gepflegt und gefüttert eine Diät von UV-abgetöteten Bakterien. Diese Verfahren können leicht Assay Lebensdauer unter verschiedenen üblichen Bedingungen angepasst werden, einschließlich einer Diät, die aus lebenden Bakterien, diätetische Einschränkung und RNA-Interferenz.
