Description:
Crimson Taq™ DNA Polymerase offers superior performance in its newly formulated PCR buffer. Crimson Taq Reaction Buffer contains a density reagent, which allows direct loading of PCR products onto a gel. In addition, Crimson Taq Reaction Buffer has trace amounts of a red dye, which serves as an indicator for homogenous reaction setup, a color aid in gel loading and a tracking dye which migrates at about 10 bp on a 1% TBE gel.
Source:
An E. coli strain that carries the Crimson Taq DNA Polymerase gene from Thermus aquaticus YT-1.
Applications:- Primer Extension
- Routine PCR
- Colony PCR
- DHPLC
- Microarray Analysis
- High-throughput PCR
Advantages:- Robust and reliable reactions
- Samples can be loaded directly onto a gel
- Ideal for high throughput applications

Quality Control for Current Lot
Quality control values for a specific lot can be found on the datacard which accompanies each product.
5 kb Lambda PCR:
25 cycles of PCR amplification of 5 ng Lambda DNA with 2.5 units of Crimson Taq DNA Polymerase in the presence of 200 μM dNTPs, 0.2 μM primers and 1X Crimson Taq Reaction Buffer resulted in a specific product.
Endonuclease Activity:
Incubation of 20 units of Taq DNA Polymerase with ThermoPol Reaction Buffer with 1 μg ϕX174 RF I DNA for 4 hours at 75°C in a 50 μl reaction resulted in <10% conversion to RF II as determined by agarose gel electrophoresis.
