ADN polimerasa AmpliTaq es una ADN polimerasa recombinante termoestable de 94 kDa obtenida mediante la expresión de una forma modificada del gen de la ADN polimerasa Thermus aquaticus (Taq) en E. coli. Es la enzima más caracterizada disponible para PCR y su naturaleza recombinante y el método de purificación proporcionan una pureza y reproducibilidad inigualables, vial a vial, lote a lote.

Características de esta enzima:

ADN polimerasa AmpliTaq es la enzima más caracterizada disponible para el proceso de PCR, un testimonio de su utilidad y eficacia general

Su perfil de actividad térmica la hace bueno para aplicaciones de PCR

Sometida a controles de calidad para garantizar resultados reproducibles

PCR fiable y resistente
El perfil de actividad térmica de ADN polimerasa AmpliTaq es fiable para aplicaciones de PCR, ya que su actividad óptima se encuentra en el mismo rango en el que se produce un recocido riguroso de cebadores (55–75 °C). La semivida de la enzima es de ∼40 minutos a 95 °C, lo que proporciona una termoestabilidad que cumple los requisitos de las aplicaciones de PCR más difíciles. Esta ADN polimerasa AmpliTaq se suministra con un tampón para PCR GeneAmp 10X II y solución de MgCl₂.

Para un rendimiento superior de PCR, recomendamos ADN polimerasa DreamTaq.

Para uso exclusivo en investigación. No apto para uso en procedimientos diagnósticos.

Preguntas frecuentes

My oligonucleotide does not appear to be the right length when I checked by gel electrophoresis. Why is this?

Oligos should be run on a polyacrylamide gel containing 7 M urea and loaded with a 50% formamide solution to avoid compressions and secondary structures. Oligos of the same length and different compositions can electrophorese differently. dC's migrate fastest, followed by dA's, dT's, and then dG's. Oligos containing N's tend to run as a blurry band and generally have a problem with secondary structure.

The primers I am using worked for PCR initially, but over time, have stopped working. What happened?

Primers should be aliquoted for single use before PCR set-up. Heat just the aliquoted primers to 94 degrees for 1 min. Quick chill the primer on ice before adding to the PCR reaction. Some primers may anneal to themselves or curl up on themselves.

I don't see a pellet in my oligo tube order. Should I ask for a replacement?

The drying method dries the primer in a thin layer along the sidewalls of the tube instead of the bottom, therefore a pellet is not always visible and should still be ready to use.

There is a ball-shaped pellet at the bottom of my oligo tube. What is this and can I still use my oligo?

If the oligo was overheated, it will appear as a “ball”-shaped pellet attached to the bottom of the tube. This should not affect the quality of the oligo, and the oligo should be readily soluble in water.

There is a green color in my lyophilized oligo. Can I still use it?

If an oligo appears green in color, this is most likely due to ink falling into the tube. The oligo should still be fully functional. The color can be removed by doing an ethanol precipitation.

Abstract

Chimpanzee Fab fragments and a derived humanized immunoglobulin G1 antibody that efficiently cross-neutralize dengue type 1 and type 2 viruses.

Authors:Goncalvez AP; Men R; Wernly C; Purcell RH; Lai CJ

Journal:Journal of Virology

PubMed ID:

Passive immunization with monoclonal antibodies from humans or nonhuman primates represents an attractive alternative to vaccines for prevention of illness caused by dengue viruses (DENV) and other flaviviruses, including the West Nile virus. In a previous study, repertoire cloning to recover Fab fragments from bone marrow mRNA of chimpanzees infected ... More

Molecular genetics of tetrahydrobiopterin (BH4) deficiency in the Maltese population.

Authors:Farrugia R; Scerri CA; Montalto SA; Parascandolo R; Neville BG; Felice AE

Journal:Molecular Genetics and Metabolism

PubMed ID:

Deficient activity of the Dihydropteridine Reductase enzyme (DHPR; EC 1.5.1.34; OMIM 261630) is due to mutations in the Quinoid Dihydropteridine Reductase gene on 4p15.3 (QDPR; RefSeq NM_000320). It results in defective recycling of tetrahydrobiopterin (BH(4)) and homozygotes have a rare form of atypical Hyperphenylalaninaemia and Phenylketonuria (aPKU). The heterozygote frequency ... More

A specific structural requirement for ergosterol in long-chain fatty acid synthesis mutants important for maintaining raft domains in yeast.

Journal:Molecular Biology of the Cell

PubMed ID:

Fungal sphingolipids contain ceramide with a very-long-chain fatty acid (C26). To investigate the physiological significance of the C26-substitution on this lipid, we performed a screen for mutants that are synthetically lethal with ELO3. Elo3p is a component of the ER-associated fatty acid elongase and is required for the final elongation ... More

Procollagen with skipping of alpha 1(I) exon 41 has lower binding affinity for alpha 1(I) C-telopeptide, impaired in vitro fibrillogenesis, and altered fibril morphology.

Authors:Cabral WA; Fertala A; Green LK; Korkko J; Forlino A; Marini JC

Journal:The Journal of Biological Chemistry

PubMed ID:

Previous in vitro data on type I collagen self-assembly into fibrils suggested that the amino acid 776-796 region of the alpha1(I) chain is crucial for fibril formation because it serves as the recognition site for the telopeptide of a docking collagen monomer. We used a natural collagen mutation with a ... More

Vibrio fischeri LuxS and AinS: comparative study of two signal synthases.

Authors:Lupp C; Ruby EG

Journal:Journal of Bacteriology

PubMed ID:

Vibrio fischeri possesses two acyl-homoserine lactone quorum-sensing systems, ain and lux, both of which are involved in the regulation of luminescence gene expression and are required for persistent colonization of the squid host, Euprymna scolopes. We have previously demonstrated that the ain system induces luminescence at cell densities that precede ... More
