PRODUCT INFORMATION
  • Great Taq Polymerase performance at a low price.
  • Choice of reaction buffers, with or without MgCl2.
  • Non-proofreading Polymerase

At -- for 1000 units list price (quantity discounts available), EconoTaq’s low price is coupled with high quality and performance.

QC specifications for EconoTaq are rigorous:

  • Greater than 99% pure by SDS gel electrophoresis (see Figure 1).
  • No detectable DNA contamination as determined by PCR using generic primers.
  • No detectable endonuclease (nicking) activity. Incubation of 10 U of EconoTaq DNA Polymerase with 1 µg of supercoiled pBR322 DNA for 16 hours at 70°C results in no detectable conversion to relaxed or linear forms by agarose gel electrophoresis.
  • No detectable exonuclease activity. Incubation of 10 U of EconoTaq DNA Polymerase with 1 µg of Hind III-cut lambda DNA for 16 hours at 70°C results in no smearing of bands on agarose gels.

EconoTaq Performance 
As shown in Figures 2 and 3 Lucigen’s EconoTaq DNA Polymerase performs as well as, or better than, more expensive Taq preparations from several other suppliers in routine PCR. EconoTaq is as effective in DNA amplification as another standard PCR enzyme, Tfl DNA polymerase (Figure 4). In this case, the background of non-specific amplification was much lower with EconoTaq (compare “+”and “–“ lanes for EconoTaq and Tfl in Figure 4). EconoTaq DNA Polymerase also offers high lot-to-lot reproducibility and reliability (Figures 2 and 4)

EconoTaq Comparison AmpliTaq

Figure 3. EconoTaq vs. AmpliTaq® (Applied Biosystems) DNA polymerase in genotyping. All PCR reactions were performed in a RoboCycler 96 (Stratagene). Hip1 genotyping was performed using the following PCR conditions: 94°C for 1min, 35 cycles of 94°C for 30sec, 62°C for 60sec, 72°C for 90sec, and 72°C for 7min. Shh, Cdo and Gas1 genotyping were performed using the following PCR conditions: 94°C for 2min, 35 cycles of 94°C for 60sec, 65°C for 60sec, 72°C for 90sec, and 72°C for 7min. All PCR reactions contained final concentrations of 1 µM of each primer, 200 µM dNTPs, 1X cresol red loading dye, and 1U of the indicated Taq polymerase. Sequences for all PCR primers have been previously published (references available).

EconoTaq Tfl Comparison

Figure 4. PCR amplification was performed under standard conditions using three different lots of EconoTaq DNA Polymerase and buffer, or duplicate reactions with Tfl DNA polymerase and buffer (Promega). Reactions contained primers specific for the 16S ribosomal RNA gene, with Bacillus genomic DNA (+) or no DNA (-) as a template (1450 bp product expected).
