ADN polimerasa Taq Hot-Start
Artículo No:EH001 Especificación:500U/1000U/5000U Storage: Conservar a -20°C
Introducción del producto:
This product is an antibody-blocked hot-start enzyme that suppresses non-specific amplification caused by primer misannealing or primer dimer formation at low temperatures. It is suitable for Hot Start PCR. Since the antibody is inactivated during the initial DNA denaturation step of the PCR reaction, there is no need for special deactivation treatment; it can be used under standard PCR conditions. The PCR product amplified using this product has an ‘A’ base added to the 3′ fin, making it directly clonable into a T-Vector. It can also be cloned into blunt-end vectors after end polishing and phosphorylation.

- After the reaction is complete, analyze the experimental results. For detailed analysis methods, refer to the PCR amplification instrument operating manual.
Precauciones:
- Please choose an appropriate annealing (extensión) temperature based on the primer design. Típicamente, the Tm value of the primers is designed to be around 60°C. For primers with lower annealing temperatures or for amplifying long fragments exceeding 200 pb, a three-step method is recommended. The extension time can be adjusted based on the length of the PCR product, GC content, and other factors. The extension time per kb of product is closely related to template complexity. Simple templates use 20 segundos, normal templates use 30 segundos, and complex templates use 1 minuto.
- The PCR reaction conditions should be set differently based on factors such as template, cebadores, length of the PCR product, y contenido de GC. The final concentration of commonly used primers can be adjusted within the range of 0.2-1.0 µM. The DNA template concentration can also be adjusted based on its concentration. Para plantillas complejas o alto contenido de GC, consider extending the denaturation/annealing or extension times, and increasing denaturation/annealing temperature.
- Use dedicated areas and pipettors before and after amplification, usar guantes, y cámbalos con frecuencia. After PCR amplification, do not open the reaction tubes directly. Place them at 4°C or -20°C to cool sufficiently before opening to minimize the risk of PCR product contamination in the experimental environment.
