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 经过如下改良:
包含不含
•GlutaMAX™•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。含有 GlutaMAX™ 补充剂的 DMEM/F-12 具有易于使用的包装形式,可显著减少有毒氨的积累,改善细胞活力和生长。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 (31331-028)。该工厂也是在 FDA 注册的医疗器械生产商,且通过 ISO 13485 标准认证。

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。

清除,缺少或降解谷氨酰胺或生长因子等促生长的基本成份会对培养物的生长速率造成影响么?

是的。如果您怀疑发生了类似情况,请移去培养基并换用新的培养基。或者,您可以添加含有促生长成份的培养基。也可使用I或II型GlutaMAX取代培养基中的谷氨酰胺,以避免谷氨酰胺被耗竭。

 

配方中含有Gibco GlutaMAX添加剂会改变L-谷氨酰胺的含量么?

在所有以GlutaMAX双肽添加剂作为L-谷氨酰胺替代品的培养基中,谷氨酰胺的浓度都与原始配方中的L-谷氨酰胺浓度处于同等的摩尔水平。

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。

Abstract
Glycine-extended progastrin processing intermediates induce H+,K(+)-ATPase alpha-subunit gene expression through a novel receptor.
Authors: Kaise M; Muraoka A; Seva C; Takeda H; Dickinson C J; Yamada T;
Journal:J Biol Chem
PubMed ID:7744746
'Although plasma levels of G-Gly are equivalent to those of gastrin, G-Gly has essentially no acute effect on gastric acid secretion. However, we have observed that inhibition of gastrin amidation leads to increased plasma concentrations of G-Gly and enhanced gastric acid secretion. We hypothesized, therefore, that G-Gly might have a ... More
Adenosine nucleotides acting at the human P2Y1 receptor stimulate mitogen-activated protein kinases and induce apoptosis.
Authors:Sellers LA, Simon J, Lundahl TS, Cousens DJ, Humphrey PP, Barnard EA,
Journal:J Biol Chem
PubMed ID:11278310
For the widely distributed P2Y receptors for nucleotides, the transductional and functional responses downstream of their coupling to G proteins are poorly characterized. Here we describe apoptotic induction and the associated differential stimulation of mitogen-activated protein (MAP) kinase family members by the human P2Y(1) receptor. The potent P2Y(1) receptor agonist, ... More
Activity of adenosine diphosphates and triphosphates on a P2Y(T) -type receptor in brain capillary endothelial cells.

PubMed ID:11156575
1. A P2Y (nucleotide) receptor activity in a clonal population (B10) of rat brain capillary endothelial cells is coupled to inhibition of adenylyl cyclase and has functional similarities to the P2Y(T) (previously designated 'P2T') receptor for ADP of blood platelets. However, the only P2Y receptor which was detectable in a ... More

All-trans-retinoic acid (t-RA) inhibits hydrogen peroxide (H(2)O(2))-induced apoptosis by inhibiting the c-Jun N-terminal kinase (JNK)-activator protein 1 (AP-1) pathway. In this report, we examined the involvement of mitogen-activated protein kinase phosphatase 1 (MKP-1) in suppression of JNK and the antiapoptotic effect of t-RA and the roles of nuclear receptors in ... More
Genetic Evidence That Protease-activated Receptors Mediate Factor Xa Signaling in Endothelial Cells.
Authors: Camerer Eric; Kataoka Hiroshi; Kahn Mark; Lease Katy; Coughlin Shaun R;
Journal:J Biol Chem
PubMed ID:11850418
The coagulation protease Factor Xa (Xa)(1) triggers a variety of cellular responses that may be important for inflammatory reactions to tissue injury. Protease-activated receptors (PAR1, PAR2, and PAR4) can mediate Xa signaling in heterologous expression systems. However, other candidate Xa receptors have been described, and the extent to which one ... More
