DMEM/F-12(Dulbecco's Modified Eagle Medium/Nutrient Mixture F-12)是一种广泛使用的基础培养基,可用于支持很多不同种类的哺乳动物细胞生长。已在 DMEM/F-12 中成功培养的细胞包括 MDCK、神经胶质细胞、成纤维细胞、人内皮细胞及大鼠成纤维细胞。我们针对广泛的细胞培养应用,提供了多种组分的 DMEM/F-12 改良培养基。使用培养基选择工具查找适合的配方。

这种 DMEM/F-12 的改良方式如下:
包含
•L-谷氨酰胺
•HEPES:
• 酚红

可提供完整配方

使用 DMEM/F-12
DMEM/F-12 是 DMEM 和 Ham's F-12 的 1:1 混合物。该配方包含 DMEM 的高浓度葡萄糖、氨基酸及维生素与 F-12 的多种组分。DMEM/F-12 不含蛋白质、脂质或生长因子。因此,DMEM/F-12 可能需要补充营养成分,通常需要添加 10% 胎牛血清 (FBS)。DMEM/F-12 使用碳酸氢钠缓冲系统,因此需要 5–10% CO2 的环境来维持生理 pH 值。

cGMP 生产和质量体系
DMEM/F-12 在位于纽约格兰德岛上符合 cGMP 要求的工厂内生产。该工厂是在 FDA 注册的医疗器械生产商,通过 ISO 13485 标准认证。为确保供应链的稳定,我们同时提供由我们的苏格兰工厂生产的相同 DMEM/F-12 产品 (31330-038)。后者亦是在FDA登记的医疗仪器生产商,且符合ISO 13485标准。

常见问题解答 (FAQ)

加入血清后的培养基可以使用多久?

通常情况下,加入血清后的培养基可使用三个星期。尽管没有正式的研究支持数据,这是我们研究人员的经验。

我的培养基是室温条件下运送来的,但注明应保存于冷藏条件下。这会有影响么?

我们会在常温下运输那些需要在冰箱中长期存放的培养基。我们对代表性的培养基配方进行了研究,结果表明这些培养基在室温下放置一周不会有问题。

我该如何去除细胞培养基中的支原体污染?

绝大部分情况下支原体污染无法从培养物中去除,只能弃用。不过也许您的培养物具有独特性,您不希望丢弃而试图去除污染。环丙沙星和Plasmocin据报导适合此种应用。如果对相关实验方案或应用感兴趣,请联系抗生素供应商或参考已发表的文献。请注意支原体很难从培养物中清除,而且容易扩散,所以请对受污染的培养物进行隔离处理,直至支原体被完全清除,另外您的实验室可能也需要彻底净化。

我发现培养物的生长速率变缓。我该如何处理?

尝试更换培养基或血清。比较培养基配方中葡萄糖、氨基酸及其他成份之间的差异。比较新旧批次的血清。增加细胞的初始接种量。最后,让细胞逐步切换到新的培养基。

我的细胞不能贴附于培养容器。我该如何处理?

如果细胞经胰酶过度消化,即可能发生此种情况。尝试使用更短时间或更低浓度的胰酶进行消化处理。支原体污染也可能造成此种问题。分离部分细胞培养物,并检测支原体感染。最后,检查培养基中的粘附因子。

Abstract
Patient-derived glioblastoma organoids as real-time avatars for assessing responses to clinical CAR-T cell therapy
Authors:Meghan Logun, Xin Wang, Yusha Sun, Stephen J Bagley, Nannan Li, Arati Desai, Daniel Y Zhang, MacLean P Nasrallah, Emily Ling-Lin Pai, Bike Su Oner, Gabriela Plesa, Donald Siegel, Zev A Binder, Guo-Li Ming, Hongjun Song, Donald M O'Rourke
Journal:Cell Stem Cell
PubMed ID:39657679
Patient-derived tumor organoids have been leveraged for disease modeling and preclinical studies but rarely applied in real time to aid with interpretation of patient treatment responses in clinics. We recently demonstrated early efficacy signals in a first-in-human, phase 1 study of dual-targeting chimeric antigen receptor (CAR)-T cells (EGFR-IL13Rα2 CAR-T cells) ... More
Fabrication of synthetic polymer coatings and their use in feeder-free culture of human embryonic stem cells.
Authors:Nandivada H, Villa-Diaz LG, O'Shea KS, Smith GD, Krebsbach PH, Lahann J,
Journal:Nat Protoc
PubMed ID:21720316
The culture of human embryonic stem (hES) cells in defined and xenogeneic-free conditions will contribute substantially to future biotechnological and medical applications. To achieve this goal, we developed the first fully defined synthetic polymer coating poly[2-(methacryloyloxy)ethyl dimethyl-(3-sulfopropyl)ammonium hydroxide] (PMEDSAH) that sustains long-term growth of hES cells in different culture media. ... More
Insulin and insulin-like growth factor I receptors utilize different G protein signaling components.
Authors:Dalle S, Ricketts W, Imamura T, Vollenweider P, Olefsky JM,
Journal:J Biol Chem
PubMed ID:11278773
We examined the role of heterotrimeric G protein signaling components in insulin and insulin-like growth factor I (IGF-I) action. In HIRcB cells and in 3T3L1 adipocytes, treatment with the Galpha(i) inhibitor (pertussis toxin) or microinjection of the Gbetagamma inhibitor (glutathione S-transferase-betaARK) inhibited IGF-I and lysophosphatidic acid-stimulated mitogenesis but had no ... More
Polycystin-1, the product of the polycystic kidney disease 1 gene, co-localizes with desmosomes in MDCK cells.
Authors:Scheffers MS, van der Bent P, Prins F, Spruit L, Breuning MH, Litvinov SV, de Heer E, Peters DJ,
Journal:Hum Mol Genet
PubMed ID:11063733
Polycystin-1 is a novel protein predicted to be a large membrane-spanning glycoprotein with an extracellular N-terminus and an intracellular C-terminus, harboring several structural motifs. To study the subcellular localization, antibodies raised against various domains of polycystin-1 and against specific adhesion complex proteins were used for two-color immunofluorescence staining. In Madine ... More
alpha-Synuclein interacts with phospholipase D isozymes and inhibits pervanadate-induced phospholipase D activation in human embryonic kidney-293 cells.

Journal:J Biol Chem
PubMed ID:11821392
alpha-Synuclein has been implicated in the pathogenesis of many neurodegenerative diseases, including Parkinson's disease and Alzheimer's disease. Although the function of alpha-synuclein remains largely unknown, recent studies have demonstrated that this protein can interact with phospholipids. To address the role of alpha-synuclein in neurodegenerative disease, we have investigated whether it ... More
