TAQ PCR (50 uL Reaction)

• 35ul ddH20
• 10ul 5X REDTAQ buffer (mix well before use!!)
• 1.0ul 10mM dNTP’s
• 1ul each Primer (50 uM stock)
• 1ul appropriate diluted template DNA
• Mix well then add 2.5ul REDTAQ polymerase

Set up reactions on ice, and keep them on ice until placing them on the PCR machine which has been pre-warmed to 94°C. Abundant templates only require 20-25 cycles for amplification; dilute/complex templates require 35-40 cycles. Extension times vary depending on target size.

• Standard PCR program:

1. 95°C for 2 min
2. 95°C for 30 sec
3. 55°C for 30 sec
4. 72°C for 2 min
5. Repeat (2-4) 35 times
6. 72°C for 5 min
7. 4°C for forever

Q5 PCR Reaction (50 uL Reaction)

• 10uL 5x Q5 Reaction Buffer
• 1uL dNTPs
• 1uL Forward Primer
• 1uL Reverse Primer
• 10uL Q5 Enhancer
• 23.5uL ddH2O
• 1-2uL Template
• Add ?uL Q5 Polymerase right before you start the PCR reaction.

Set up reactions on ice, making sure to keep Q5 Polymerase on ice until needed.

Phusion PCR

• 35ul ddH20
• 10ul 5X Phusion GC buffer
• 1.0uL DMSO
• 1.5ul 10 mM dNTP’s
• 1ul each Primer (50 uM stock)
• 1ul appropriate diluted template DNA
• 0.5ul Phusion Polymerase

• Standard Phusion PCR program:

1. 95°C for 2 min
2. 95°C for 30 sec
3. 55°C for 30 sec
4. 72°C for 2 min
5. Repeat (2-4) 35 times
6. 72°C for 5 min
7. 4°C for forever

Standard 1% Agarose Gel

• 75ml of 1X TAE buffer and 0.75 grams of agarose (regular agarose, not low melt). Warm in microwave for about 60-90 seconds or until the agarose is completely dissolved.
• With gloves on, add 1 drop (~6ul of 1mg/ml) ethidium bromide and swirl to mix.
• Allow the flask to cool until the glass feels warm/hot, then pour into gel bed. Insert appropriate comb and allow to cool until solid.

Low-melt Agarose Gel

• Mix 0.75g of low-melt agarose with 75mL of TAE. Caution: Low-melt heats more quickly than standard agarose in the microwave.
• Add 5ul of ethidium bromide to the agarose solution before casting
• Use a large-tooth comb to form wells that will accommodate ~40-50µl of material.
