PCR of ADA Mutations

Goals

  • Prepare ADA primers in order to conduct a polymerase chain reaction (PCR)
  • Run HRP Luminol Assay

Preparation

  • Assigned Primer= ADA K110A F (forward primer)
    • Sequence Issue number: 87635082
    • Sequence: ATT TGG CCA AAT GGG CAG TTA TTG AA
    • TM= 65.5°C
    • MW= 16833.0 g/mol
    • 33.4 nm= .56 mg ( amount of present plasmid)

Concentration of plasmid needed for experiment= 100ng/μL

  • Calculations

.56mg= 5600 ng M1V1= M2V2 5600 ng/μL x V1= 100ng x 1000μL

  • (The container containing the plasmid only had room for 1mL of water to be added- as a result, a dilution needed to be done in order to get the appropriate concentration.

V2= 17.857μL is the amount of plasmid solution pipetted out in order to get a concentration of 100ng/μL

Procedure

  1. 1mL of deionized water was added to .56mg of ADA K110A F
  2. 17.86μL of this solution was pipetted out and added to a centrifuge tube. 982.14μL of autoclaved water was then added to this sample in order to dilute it to 100ng/μL.
  3. Next, 2 50μL solutions were made with the following components in microcentrifuge tubes. The DNA polymerase was added last.
Component Volume [μL]
Distilled water 40.6
10X cloned Pfu buffer 5
25 mM dNTPs 0.4
100 ng/μL DNA template 1
Forward primer (K110 f) 1
Reverse primer (K110A r) 1
2.5 U/μL PfuTurbo DNA polymerase 1
  • Immediately after the addition of the DNA polymerase, the two sample solutions were placed in a thermocycler. The heating and cooling cycle of the thermocycler for the samples is as follows.
  1. Heat for 2 minutes at 95°C.
  2. Heat for 30 seconds at 95°C.
  3. Heat for 30 seconds at 57°C.
  4. Heat for 8 min at 72°C.
  5. Repeat steps two through four 30 times.
  6. Heat for 10 minutes at 72°C.
  7. Chill at 0°C until the samples needed again.
