Opti-MEM™ I 减血清培养基是一种经过改良的最低必需培养基 (MEM),能够使胎牛血清添加量减少至少 50%,而生长速率或形态无变化。还推荐 Opti-MEM™ I 培养基与阳离子脂质体转染试剂(如 Lipofectamine™ 试剂)配套使用。Opti-MEM™ I 培养基可用于各种悬浮和贴壁的哺乳动物细胞,包括 Sp2、AE-1、CHO、BHK-21、HEK 和原代成纤维细胞。针对广泛的细胞培养应用,提供了多种组分的 Opti-MEM™ I 改良培养基。

这种 Opti-MEM™ I 的改良方式如下:
包含
•L-谷氨酰胺
• 酚红

Opti-MEM™ I 培养基的使用
Opti-MEM™ I 减血清培养基是一种内含胰岛素、转铁蛋白、次黄嘌呤、胸苷和微量元素的独特培养基。这些附加组分可使血清添加量减少至少 50%。Opti-MEM™ I 培养基使用碳酸氢钠缓冲系统 (2.4 g/L),因此需要 5–10% CO2 环境来维持生理 pH 值。

cGMP 生产和质量体系
Opti-MEM™ I 在位于纽约格兰德岛的符合 cGMP 要求的工厂内生产。该工厂是在FDA登记的医疗器械生产商,且通过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 Opti-MEM™ I 产品 (31985-047)。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)

在配制复合物之前,应使用何种溶液稀释我的RNAi双链和Lipofectamine RNAiMAX?

我们建议使用Opti-MEM I减血清培养基(货号31985062)。

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。

Abstract
Identification of a novel redox-sensitive gene, Id3, which mediates angiotensin II-induced cell growth.
Authors:Mueller Cornelius; Baudler Stephanie; Welzel Hilke; Böhm Michael; Nickenig Georg;
Journal:Circulation
PubMed ID:12021231
BACKGROUND: Reactive oxygen species, such as superoxide (O(2)(-)), are involved in the abnormal growth of various cell types. Angiotensin II (Ang II) is one of the most potent inducers of oxidative stress in the vasculature. The molecular events involved in Ang II-induced proliferation of vascular smooth muscle cells (VSMCs) are ... More
Regulation of cortical dendrite development by Slit-Robo interactions.
Authors:Whitford Kristin L; Marillat Valérie; Stein Elke; Goodman Corey S; Tessier-Lavigne Marc; Chédotal Alain; Ghosh Anirvan;
Journal:Neuron
PubMed ID:11779471
Slit proteins have previously been shown to regulate axon guidance, branching, and neural migration. Here we report that, in addition to acting as a chemorepellant for cortical axons, Slit1 regulates dendritic development. Slit1 is expressed in the developing cortex, and exposure to Slit1 leads to increased dendritic growth and branching. ... More
Cloning and characterization of freac-9 (FKHL17), a novel kidney-expressed human forkhead gene that maps to chromosome 1p32-p34.
Authors: Ernstsson S; Betz R; Lagercrantz S; Larsson C; Ericksson S; Cederberg A; Carlsson P; Enerbäck S;
Journal:Genomics
PubMed ID:9403061
'We describe the cloning of a near full-length cDNA of 4258 nucleotides encoding freac-9 (HGMW-approved symbol FKHL17), a novel human forkhead gene. The 5'' untranslated region is unusual since it is very long, 2127 nucleotides, and contains 15 upstream AUG codons. Hybridization to a panel consisting of RNA derived from ... More
Noninfectious virus-like particles produced by Moloney murine leukemia virus-based retrovirus packaging cells deficient in viral envelope become infectious in the presence of lipofection reagents.
Authors:Sharma S, Murai F, Miyanohara A, Friedmann T
Journal:Proc Natl Acad Sci U S A
PubMed ID:9380714
Retrovirus packaging cell lines expressing the Moloney murine leukemia virus gag and pol genes but lacking virus envelope genes produce virus-like particles constitutively, whether or not they express a transcript from an integrated retroviral provirus. In the absence of a proviral transcript, the assembled particles contain processed gag and reverse ... More
Human T-cell leukemia virus type I Tax protein transactivates RNA polymerase III promoter in vitro and in vivo.
Authors: Piras G; Dittmer J; Radonovich M F; Brady J N;
Journal:J Biol Chem
PubMed ID:8702791
Tax protein of the human T-cell lymphotropic virus type 1 (HTLV-I) is critical for viral replication and is a potent transcriptional activator of viral and cellular polymerase II (pol II) genes. We report here that Tax is able to transactivate a classical pol III promoter, VA-I. In cotransfection experiments, Tax ... More
