Le DMEM (Dulbecco’s Modified Eagle Medium) est un milieu de culture basal largement utilisé pour prendre en charge la croissance de nombreuses cellules de mammifères différentes. Les cellules cultivées avec succès dans du milieu DMEM comprennent les fibroblastes primaires, les neurones, les cellules gliales, les HUVEC et les cellules musculaires lisses, ainsi que les lignées cellulaires telles que HeLa, 293, Cos-7, et PC-12. Nous proposons une variété de modifications de DMEM pour une gamme d’applications de culture cellulaire. Trouvez la formulation la mieux adaptée à l’aide de l’outil de sélection de milieux de culture.

Ce milieu DMEM est modifié comme suit :
AvecSans
• Haute teneur en glucose• L-glutamine
• Rouge de phénol• HEPES
• Pyruvate de sodium

La formulation complète est disponible.

Utilisation du DMEM
Le DMEM est unique par rapport aux autres milieux de culture, car il contient une concentration d’acides aminés et de vitamines 4 fois supérieure à celle trouvée dans le milieu minimum essentiel d’Eagle original. À l’origine, le DMEM était formulé avec peu de glucose (1 g / l) et de pyruvate de sodium, mais il est souvent utilisé avec des niveaux supérieurs de glucose, avec ou sans pyruvate de sodium. Le DMEM ne contient ni protéines, ni lipides, ni facteurs de croissance. C’est pourquoi le milieu DMEM nécessite une supplémentation, en général avec 10 % de sérum de veau fœtal (SVF). Le milieu DMEM utilise un système de tampon au bicarbonate de sodium (3,7 g / l) et, par conséquent, nécessite un environnement contenant 5 à 10 % de CO2 pour préserver le pH physiologique.

Système de qualité et fabrication conforme aux BPFa
Le milieu DMEM est fabriqué sur un site conforme aux BPFa situé à Grand Island, dans l’État de New York. Ce site est homologué par la FDA comme fabricant de dispositifs médicaux et il est certifié ISO 13485. Pour assurer la continuité de la chaîne d’approvisionnement, nous proposons un produit DMEM comparable fabriqué dans notre installation écossaise (21969-035). Ce site est homologué par la FDA comme fabricant de dispositifs médicaux et il est certifié ISO 13485.

Foire aux questions (FAQ)

What is the manganese concentration in DMEM? Do you offer manganese-free DMEM?

Manganese is not present in the formulation of our catalog DMEM media products.

How long can I keep my media after supplementing with serum?

Generally speaking, media can be used for up to three weeks after supplementation with serum. There are no formal studies to support this, but it is the rule of thumb used by our scientists.

My medium was shipped at room temperature but it is supposed to be stored refrigerated. Is it okay?

We routinely ship media that require long-term storage in the refrigerator at room temperature. We have done studies on representative media formulations to show that media can be at room temperature for up to a week without a problem.

How can I remove mycoplasma contamination from my cell culture medium?

Very often mycoplasma contamination cannot be removed from the culture so it should be discarded. You may have a unique culture that you prefer not to discard and would like to try to clean it. Ciprofloxacin and Plasmocin have reportedly been used for this application. If interested in a protocol or directions for use, check with the antibiotic supplier or published literature. Note that mycoplasma are very difficult to remove from culture and spread easily so the treated cultures should be quarantined until clear of mycoplasma, and your laboratory should be thoroughly cleaned.

I see a decrease in growth of my culture. What should I do?

Try changing the medium or serum. Compare media formulations for differences in glucose, amino acids, and other components. Compare an old lot of serum with a new lot. Increase initial cell inoculums. Lastly, adapt cells sequentially to new medium.

Subcellular targeting of RGS9-2 is controlled by multiple molecular determinants on its membrane anchor, R7BP.
Authors:Song JH, Waataja JJ, Martemyanov KA,

'RGS9-2, a member of the R7 RGS protein family of neuronal RGS (Regulators of G protein Signaling), is a critical regulator of G protein signaling. In striatal neurons, RGS9-2 is tightly associated with a novel palmitoylated protein - R7BP (R7 family Binding Protein). Here we report that R7BP acts to ... More
