Multi site directed mutagenesis

Single Primer Method

This protocol only uses one oligo per mutation site (cuts the oligo cost in half) and can mutate more than one site at a time. While this protocol is less reliable than the previous protocol (only ~25% of colonies will contain the desired mutation(s)), if you're doing multiple mutations on the same piece of DNA than this can save you many days of work by just sequencing a few more colonies. In this protocol there is an initial Kinase (phosphorylation) reaction to allow your primers to be available for ligation. The polymerase will extend from one primer to another and then the Taq ligase will seal the nick. This allows multiple mutations to be done at the same time.

Method

1. Design mutagenesis primer(s). The targeted mutation should be in the middle of the primer. Design your primers (including the mutations) to have a Tm >=78°C.
2. Purify template plasmid from a dam+ E. coli strain via miniprep.
3. Set up mutagenesis PCR mix:

16 μL Water
1.5 μL DMSO(100%)
0.5 μL MgSO4(50 µM)
10 μL Phusion HF Buffer
5 μL T4 Ligase Buffer
5 μL 10x Taq Ligase Buffer
0.5 μL Each Mutagenesis Primer (at 40 µM)
2 μL Reverse Biobrick Primer
2 μL dNTPs (100mM)
2 μL Template
2 μL PNK
2 μL Taq Ligase
1 μL Phusion Polymerase (hotstart)

1. Run PCR

• 37°C for 30 minutes (this is the kinase step)
• 95°C for 3 minutes
• Run the following for 20 cycles:
  • 95°C for 1 minute
  • 55°C for 1 minute
  • 65°C for 30 sec/kb of plasmid length minimum
  • 4°C infinite

1. Add 1μL DpnI restriction enzyme to the PCR tube directly. (Purification is not necessary)
2. Incubate 4-6 hours at 37°C.
3. Purify PCR product and elute into 30μL.
4. Transform 3μL purified DNA into highly competent cells.
5. Screen the transformants for the desired mutation using restriction digest or sequencing.

Notes Because the inital kinase step could lead to non-specific binding, it would be best to use a hot-start polymerase for this procedure. Any combination of DMSO and MgSO4 has shown significant improvments in product.

Devices

NanoDrop 2000, UV-Vis Spectrophotometer

Our NanoDrop spectrophotometer

A Thermo Scientific NanoDrop® 2000 spectrophotometer was used to determine the concentrations of our plasmids after miniprep.

This microvolume spectrophotometer can be used to measure the concentration and purity of DNA, RNA or protein samples. Having a wide spectral range (190-840nm) allows for measuring a variety of samples types such as peptides, DNA, RNA, purified protein and even gold nanoparticles. Even for highly concentrated samples no dilutions are required. Results are obtained in less than 15 seconds from sample pipetting to wiping the pedestal clean. For the measurement only 0.5 – 2uL of the samples are needed. The software with an intuitive user interface allows for classical NanoDrop applications such as nucleic acids, protein A280, colorimetric assays and new user defined custom methods.
