General description
Application
Sie eignet sich für die nicht selektive Kultivierung von E.-coli-Stämmen für das Klonen, die DNA-Plasmidproduktion und die Produktion rekombinanter Proteine. Ebenso geeignet für die selektive Kultivierung bei entsprechender Zugabe von Antibiotika, einschließlich derer, die Lösungen mit geringem Salzanteil erfordern, wie Zeocin®.
Features and Benefits
- Eine budgetfreundliche Alternative zu vorgefüllten Platten
- Einfaches Hochskalieren durch Verwenden größerer Packungsgrößen
- Standardmäßige Formulierung
Preparation Note
2. Unter Rühren bis zum Kochen erhitzen, bis sich alle Bestandteile vollständig aufgelöst haben.
3. Bei 121 °C 15 Minuten lang autoklavieren.
Zur Herstellung des Lennox-L-Agars: 1 g Glucose zugeben und obiger Herstellungsvorschrift folgen. Zur Herstellung des Enquist- und Sternberg-Mediums: 10 mL steriles 1 M Magnesiumsulfat nach dem Autoklavieren aseptisch zugeben.

Which bacterial culture medium is the best choice for my application?
1 answer-
Each of the broths will likely grow E. coli very well, but there are still general guidelines for choosing a broth when you are working without a protocol. Generally:LB - Miller and LB - Lennox are used for E. coli growth and maintanence, DNA plasmid production and protein production. The Lennox formulation has a lower salt content required for some salt-sensitive selection antibiotics.LB - Luria low salt is used for special applications where the E. coli growth or other constraints require the lowest possible salt content.Terrific Broth is used for higher yield protein production and high yield DNA plasmid production, because of the faster growth of the E. coli in this medium.SOB is used for protein production, DNA plasmid production and the generation of high-efficiency competent cells.SOC is used for initial growth of competent cells and the transformation procedure.

Will adding magnesium to the culture medium increase cell density?
1 answer-
In microbial broth formulations that do not already contain magnesium, the addition of 10-20 mM MgCl2 or MgSO4 may increase cell densities. You may need to also increase the shaking speed of the incubator.

What are the differences among the Luria, Lennox and Miller LB formulations?
1 answer-
LB, (originally termed lysogeny broth) was initially composed of tryptone, yeast extract, NaCl and glucose. Soon after, the glucose was omitted (Miller's version), and later the NaCl content lowered by half (Lennox's version). For some applications, even lower salt is required (Luria's low salt version).
