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。

pCR2.1-TOPO和pCR4-TOPO载体有什么区别?

两个载体的骨架非常相似。主要的不同在于pCR4-TOPO载体测序引物位点距离PCR产物插入位点仅33 bp。这使得对插入序列进行测序时需要读取的载体序列能最小化,从而使pCR4-TOPO载体非常适合进行测序应用。

pCR2.1-TOPO 和pCRII-TOPO载体的区别是什么?

两个载体的骨架非常相似。主要的不同在于pCRII-TOPO 载体是一个双启动子载体,包含SP6和T7启动子用于体外转录/测序,而 pCR2.1-TOPO仅包含T7启动子用于体外转录/测序。两个载体均含有M13 正向和反向引物位点用于测序或PCR检测。

你们的TOPO克隆试剂盒包含一个对照模板和一个对照引物。我可以获得对照模板的序列吗?

对照模板的序列是受专利保护的。

Abstract
Cloning and functional expression of a thyrotropin receptor cDNA from rat fat cells.
Authors:Endo T; Ohta K; Haraguchi K; Onaya T;
Journal:J Biol Chem
PubMed ID:7738021
Thyrotropin receptor (TSH-R) has been thought to be thyroid-specific, but, by Northern blot analysis, we found that rat adipose tissue expressed TSH-R mRNAs in amounts approaching those in the thyroid. To investigate the function of TSH-R from adipose tissue, we screened a rat fat cell lambda gt11 cDNA library for ... More
Dual DNA binding specificity of ADD1/SREBP1 controlled by a single amino acid in the basic helix-loop-helix domain.
Authors:Kim JB, Spotts GD, Halvorsen YD, Shih HM, Ellenberger T, Towle HC, Spiegelman BM
Journal:Mol Cell Biol
PubMed ID:7739539
'Adipocyte determination- and differentiation-dependent factor 1 (ADD1), a member of the basic helix-loop-helix (bHLH) family of transcription factors, has been associated with both adipocyte differentiation and cholesterol homeostasis (in which case it has been termed SREBP1). Using PCR-amplified binding analysis, we demonstrate that ADD1/SREBP1 has dual DNA sequence specificity, binding ... More
Sequential mutations in the interleukin-3 (IL3)/granulocyte-macrophage colony-stimulating factor/IL5 receptor beta-subunit genes are necessary for the complete conversion to growth autonomy mediated by a truncated beta C subunit.
Authors:Hannemann J, Hara T, Kawai M, Miyajima A, Ostertag W, Stocking C
Journal:Mol Cell Biol
PubMed ID:7739524
'An amino-terminally truncated beta C receptor (beta C-R) subunit of the interleukin-3 (IL3)/granulocyte-macrophage colony-stimulating factor/IL5 receptor complex mediates factor-independent and tumorigenic growth in two spontaneous mutants of a promyelocytic cell line. The constitutive activation of the JAK2 protein kinase in these mutants confirms that signaling occurs through the truncated receptor ... More
A powerful transgenic tool for fate mapping and functional analysis of newly generated neurons.
Authors:Zhang J, Giesert F, Kloos K, Vogt Weisenhorn DM, Aigner L, Wurst W, Couillard-Despres S
Journal:BMC Neurosci
PubMed ID:21194452
Lack of appropriate tools and techniques to study fate and functional integration of newly generated neurons has so far hindered understanding of neurogenesis' relevance under physiological and pathological conditions. Current analyses are either dependent on mitotic labeling, for example BrdU-incorporation or retroviral infection, or on the detection of transient immature ... More
Classical and non-classical Major Histocompatibility Complex class I gene expression in in vitro derived bovine embryos.
Authors:Doyle J, Ellis SA, O'Gorman GM, Aparicio Donoso IM, Lonergan P, Fair T
Journal:J Reprod Immunol
PubMed ID:19682752
The role of the Major Histocompatibility Complex class I (MHC-I) genes in human and mouse preimplantation embryo development has received considerable attention. In contrast, information concerning the role of these genes in bovine embryo development is limited. The objective of the current study was to characterize the expression pattern of ... More
