两性霉素 B 是 Fungizone 的通用版本。“Fungizone”是 E.R.Squibb & Sons, LLC 的商标。两性霉素 B 是一种由 结节链霉菌产生的抗真菌剂。它通过提高真菌细胞膜通透性防止真菌生长。它会主动与甾醇结合并导致微孔形成。它用于防止细胞培养受到酵母菌和多细胞真菌污染。Gibco 两性霉素 B 在每 mL 蒸馏水中含有 250 μg 两性霉素 B 和 205 μg 脱氧胆酸钠。建议工作浓度在 0.25 至 2.50 μg/mL 之间。

两地 cGMP 生产
为确保供应链的稳定,同时在位于纽约格兰德岛和英国苏格兰的两家独立工厂生产 Gibco 两性霉素 B。两个地点都符合 cGMP 生产要求,并通过 ISO 13485 标准认证,是在 FDA 登记的医疗器械生产商。

常见问题解答 (FAQ)

我该如何对我的培养物去污染?

当不可替代的培养物被污染时,研究人员可能会试图控制或消除污染。

1.用户需要确定污染的来源是细菌、真菌、支原体,还是酵母。请点击此处(https://www.thermofisher.com/us/en/home/references/gibco-cell-culture-basics/biological-contamination/bacterial-contamination.h%E2%84%A2l)阅读更多信息,以了解每一种污染的特性。
2.把受污染的培养物跟其他细胞系进行隔离。
3.使用一款实验室消毒剂清洁培养箱和层流柜,并检查HEPA过滤器。
4.高浓度的抗生素和抗真菌剂可能对一些细胞系有毒性。因此,需进行剂量效应测试来确定何种浓度水平的抗生素或抗真菌会造成毒性。这一操作对于使用Gibco Fungizone一类的抗真菌剂或泰乐菌素一类的抗生素尤其重要。

下列操作为我们确定毒性水平和对培养物去污染的推荐步骤:

1.对细胞进行分离,计数, 使用不含抗生素的培养基稀释将细胞稀释至常规传代的浓度。
2.将细胞悬液分入多孔培养板或几个小培养瓶中。向每一培养孔中添加不同浓度的特定抗生素。举例来说,我们推荐以如下浓度测试Gibco Fungizone试剂:0.25,0.50,1.0,2.0,4.0和8.0 µg/mL。
3.每日观察细胞脱落,出现空泡,融汇度降低,细胞变圆一类的毒性效应。
4.一旦确定了抗生素的毒性浓度水平,就可使用比毒性浓度低一至两倍的抗生素浓度来培养细胞两至三代。
5.在不含抗生素的培养基中培养一代。
6.重复步骤4。
7.在不含抗生素的培养基中培养细胞四至六代,以确定污染是否成功被消除。

PC12 Cell Line: Cell Types, Coating of Culture Vessels, Differentiation and Other Culture Conditions.
Authors:Wiatrak B, Kubis-Kubiak A, Piwowar A, Barg E
Journal:Cells
PubMed ID:32295099
'The PC12 cell line is one of the most commonly used in neuroscience research, including studies on neurotoxicity, neuroprotection, neurosecretion, neuroinflammation, and synaptogenesis. Two types of this line are available in the ATCC collection: traditional PC12 cells grown in suspension and well-attached adherent phenotype. PC12 cells grown in suspension tend ... More
Generation of human brain region-specific organoids using a miniaturized spinning bioreactor.
Authors:Qian X, Jacob F, Song MM, Nguyen HN, Song H, Ming GL
Journal:Nat Protoc
PubMed ID:29470464
Human brain organoids, 3D self-assembled neural tissues derived from pluripotent stem cells, are important tools for studying human brain development and related disorders. Suspension cultures maintained by spinning bioreactors allow for the growth of large organoids despite the lack of vasculature, but commercially available spinning bioreactors are bulky in size ... More
Analysis of HspB1 (Hsp27) Oligomerization and Phosphorylation Patterns and Its Interaction with Specific Client Polypeptides.
Authors:Arrigo AP
Journal:Methods Mol Biol
PubMed ID:29177658
Human HspB1 (also denoted as Hsp27) belongs to the family of small (or stress) proteins (sHsps). The family, which contains ten members including aA,B-crystallin polypeptides, is characterized by a conserved C-terminal a-crystallin domain and molecular weights ranging from 20 to 40 kDa. Here, procedures are described for analyzing the dynamic oligomerization ... More

PubMed ID:30224542
Head and neck squamous cell carcinomas (HNSCC) develop in fields of genetically altered cells. These fields are often dysplastic and a subset can be recognized as (erythro)leukoplakia, but most are macroscopically invisible. There is a lack of adequate treatment options to eradicate these fields, whereas they underlie the development of ... More
