PCR on Tyrosinase

I ran a new PCR on the Tyrosinase since I realized that the band from the last PCR on this gene was incorrect (too high than expected). The gene Tyrosinase is about 1900 nt.

PCR Mix (100 ul):

  • Fprimer 50 uM 1 ul
  • Rprimer 50 uM 1 ul
  • dNTP 10 mM 2 ul
  • Buffer 5X 20 ul for phusion polymerase
  • Buffer 10X 10 ul for fermenta (Pfu) polymerase
  • phusion polymerase 1 ul
  • fermenta (Pfu) polymerase 1 ul
  • H2O 75 ul for phusion polymerase
  • H2O 85 ul for fermenta (Pfu) polymerase
  • DNA template 1 colony

Primer dilutions:

100 uM gets a 1:2 dilution to become 50 uM

cV = cV

100V = 50*10ul

V = 500 / 100 = 5 ul primer and fill up to 10 ul with H2O.

I aliquate the 100 ul in four PCR tubes, each with 25 ul PCR mix.

PCR prgm:

98 °C 2 min

2 * 29 cycles of:

  • 98 °C 30 sec
  • 50-72 °C 30 sec
  • 72 °C 2 min

72 °C 1 min

4 °C ∞


Agarose gel on Tyrosinase

I ran a 1 % agarose gel on the tyrosinase PCR productes.

Ladder: FastRuler™ Middle Range DNA Ladder, ready-to-use, 100-5000 bp Fermentas

Arrangement on gels:

1 = 50 °C - 4 = 72 °C

P1 and 2 look like they have succesfully PCR:ed tyrosinase.


Sequencing yCCS

I send two samples of yCCS for sequencing.

  • 15 ul vector
  • 1.5 ul 10uM VF2 primer
