常见问题解答 (FAQ)

我可将感受态细胞存储在液氮中吗?

我们不建议将感受态细胞保存在液氮中,因为极端温度会损害细胞。另外,装感受态细胞的塑料管子可能承受不了如此低的温度,从而发生破裂。

我应该如何存储我的感受态E. Coli?

我们推荐将感受态细胞存储在-80摄氏度。高于这个温度,即使存储时间很短,也会显著降低其转化效率。

Pichia pastoris和S. cerevisiae的培养基有哪些不同种类?

以下是用于培养Pichia pastoris和S. cerevisia的营养丰富型和基本培养基:

营养丰富型培养基:

适用于S. cerevisiae和Pichia pastoris
•YPD(YEPD):酵母提取物、蛋白胨和葡聚糖
•YPDS:酵母提取物、蛋白胨、葡聚糖和山梨醇

仅适用于Pichia pastoris
•BMGY:缓冲型甘油复合培养基
•BMMY:缓冲型甲醇复合培养基

基本培养基(又名缺陷型培养基):

适用于S. cerevisiae
•SC(SD):完全合成培养基(YNB、葡聚糖(或棉籽糖或半乳糖)以及氨基酸)

适用于Pichia pastoris

•MGY:基本甘油培养基
•MD:基本葡聚糖培养基
•MM:基本甲醇培养基
•BMGH:缓冲型基本甘油培养基
•BMMH:缓冲型基本甲醇培养基

Schizosaccharomyces pombe能否识别Saccharomyces cerevisiae的α-因子分泌信号?

当α因子基因中的P因子被替换为α时,S. pombe不能生成P因子。但是,当P因子基因中的α因子被替换为P时,S. pombe能够生成α因子。有反面证据表明,S. pombe能够加工其自身的交配因子切割位点,但并不是S. cerevisiae α因子的所有切割位点。最好使用一个更通用的信号序列(而不是前导信号序列,如α)。如果必须走前导路线,最好使用S. pombe的P因子前导而不是S. cerevisiae的α前导。

你们是否提供TOPO适应型酵母表达载体?

是的,我们提供pYES2.1/V5-His-TOPO载体,它是pYES2.1 TA表达试剂盒(货号K415001)的一部分,可将Taq聚合酶扩增的PCR产物直接克隆到Saccharomyces cerevisiae中并利用半乳糖调控其表达。

Abstract
Identification of a family of animal sphingomyelin synthases.
Authors:Huitema K, Van Den Dikkenberg J, Brouwers JF, Holthuis JC,
Journal:EMBO J
PubMed ID:14685263
'Sphingomyelin (SM) is a major component of animal plasma membranes. Its production involves the transfer of phosphocholine from phosphatidylcholine onto ceramide, yielding diacylglycerol as a side product. This reaction is catalysed by SM synthase, an enzyme whose biological potential can be judged from the roles of diacylglycerol and ceramide as ... More
Cell cycle control of Cdc7p kinase activity through regulation of Dbf4p stability.
Authors:Oshiro G, Owens JC, Shellman Y, Sclafani RA, Li JJ
Journal:Mol Cell Biol
PubMed ID:10373538
'In Saccharomyces cerevisiae, the heteromeric kinase complex Cdc7p-Dbf4p plays a pivotal role at replication origins in triggering the initiation of DNA replication during the S phase. We have assayed the kinase activity of endogenous levels of Cdc7p kinase by using a likely physiological target, Mcm2p, as a substrate. Using this ... More
Regulation of stress response signaling by the N-terminal dishevelled/EGL-10/pleckstrin domain of Sst2, a regulator of G protein signaling in Saccharomyces cerevisiae.
Authors: Burchett Scott A; Flanary Paul; Aston Christopher; Jiang Lixin; Young Kathleen H; Uetz Peter; Fields Stanley; Dohlman Henrik G;
Journal:J Biol Chem
PubMed ID:11940600
'All members of the regulator of G protein signaling (RGS) family contain a conserved core domain that can accelerate G protein GTPase activity. The RGS in yeast, Sst2, can inhibit a G protein signal leading to mating. In addition, some RGS proteins contain an N-terminal domain of unknown function. Here ... More
Genetic screens in yeast to identify mammalian nonreceptor modulators of G-protein signaling.
Authors:Cismowski MJ, Takesono A, Ma C, Lizano JS, Xie X, Fuernkranz H, Lanier SM, Duzic E
Journal:Nature Biotechnology
PubMed ID:10471929
We describe genetic screens in Saccharomyces cerevisiae designed to identify mammalian nonreceptor modulators of G-protein signaling pathways. Strains lacking a pheromone-responsive G-protein coupled receptor and expressing a mammalian-yeast Galpha hybrid protein were made conditional for growth upon either pheromone pathway activation (activator screen) or pheromone pathway inactivation (inhibitor screen). Mammalian ... More
Pheromone-dependent Ubiquitination of the Mitogen-activated Protein Kinase Kinase Ste7.
Authors: Wang Yuqi; Dohlman Henrik G;
Journal:J Biol Chem
PubMed ID:11864977
Many cell signaling pathways are regulated by phosphorylation, ubiquitination, and degradation of constituent proteins. As with phosphorylation, protein ubiquitination can be reversed, through the action of ubiquitin-specific processing proteases (UBPs). Here we have analyzed 15 UBP disruption mutants in the yeast Saccharomyces cerevisiae and identified one (ubp3Delta) that acts specifically ... More
