Los kits de promotores dobles TOPO™ TA Cloning™ se han concebido para la clonación rápida y eficaz y la posterior transcripción in vitro. Estos incluyen el vector pCR™II-TOPO™ TA con promotores dobles de T7 y SP6. Al eliminar la tediosa y laboriosa clonación de sitios de restricción, la clonación TOPO™ es el método más fiable, ya que solo tarda 5 minutos utilizando un protocolo de 3 pasos y produce recombinantes de hasta un 95 %.

Entre las prácticas características del kit de promotor doble TOPO™ TA Cloning™ se incluyen:
• Salientes 3´-T para la ligadura directa de productos de PCR amplificados con Taq
• Promotores de T7 y SP6 para una transcripción in vitro eficaz
• Sitios de primers directos e inversos M13 para secuenciación o detección de PCR
• 16 prácticos sitios de restricción, incluido EcoRI, que flanquean su inserto para su posterior escisión o subclonación
• Diversas opciones de resistencia a kanamicina y ampicilina en E. coli
• Fácil detección de colonias azules/blancas para la selección de recombinantes
• Incluye células competentes OneShot™ TOP10 para una mayor comodidad y una máxima eficacia de la clonación

Preguntas frecuentes

Can I store my competent E. coli in liquid nitrogen?

We do not recommend storing competent E. coli strains in liquid nitrogen as the extreme temperature can be harmful to the cells. Also, the plastic storage vials are not intended to withstand the extreme temperature and may crack or break.

How should I store my competent E. coli?

We recommend storing our competent E. coli strains at -80°C. Storage at warmer temperatures, even for a brief period of time, will significantly decrease transformation efficiency.

What is the difference between the pCR2.1-TOPO and pCR4-TOPO vectors?

The vector backbones for both of these vectors are very similar. The main difference is that the pCR4-TOPO vector has sequencing primer sites located as close as 33 base pairs from the PCR product insertion site. This minimizes the amount of vector DNA sequence that needs to be read before reaching the sequence of the insert, making the pCR4-TOPO vector very useful for sequencing applications.

What is the difference between the pCR2.1-TOPO and pCRII-TOPO vectors?

The vector backbones for both of these vectors are very similar. The main difference is that the pCRII-TOPO vector is a dual promoter vector, containing the SP6 and T7 promoters for in vitro transcription/sequencing, whereas the pCR2.1-TOPO vector contains only the T7 promoter for in vitro transcription/sequencing. Both vectors contain the M13 Forward and Reverse primer sites for sequencing or PCR screening.

Your TOPO cloning kits contain a control template and control primers. Can I obtain the sequence of the control template?

The sequence of the control template is proprietary.

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.

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.

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.

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.

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
