Splet13. maj 2024 · PCR involves heating (94-98°C) to denature DNA into single strands, lowering the temperature to allow primer binding (50-64°C), and then increasing the temperature (72-80°C) to allow the polymerase to synthesize the opposite strand to create double-stranded DNA. This process is repeated 15-40 times to create many copies of the DNA. SpletIncubation procedure 12.5 mg activated calf thymus DNA and 0.1 mCi [α-32 P]dCTP are incubated with 0.01 to 0.1 U Pwo SuperYield DNA Polymerase in 50 μl incubation buffer with a paraffin-oil overlay at +70 °C for 30 minutes. The amount of incorporated dNTPs is determined by trichloroacetic acid precipitation followed by scintillation counting.

SpletTo prevent potential digestion of your samples, proteinase K is inactivated after incubation. The common temperature for inactivation is 95°C. Even in the typical mouse-tail protocol, proteinase K is regularly used to inhibit harmful nucleases. And the addition of proteinase K occurs during the digestion step.

SpletThe first step in the PCR is generally performed at 94–96°C for 2–20 min. This step denatures the initial template into single- stranded DNA and also activates hot-start polymerases. While 2–3 min at 94–95°C is usually sufficient to fully denature total genomic DNA, some hot-start polymerases require 15 or 20 min at 95°C to be activated.
