CA4 PCR #3 7/3/19

E27 E82 E29 E30 E31 E32 E33 E34 E35 E36 E37 E40

Procedure

Samples E27 E82 E29 E30 E31 E32 E33 E34 E35 E36 E37 E40 were used in this PCR (polimerase chain reaction) reaction

First A Master Mix of water, 2x mytaq mix, CA4.86R Primer (concentration: 10 micromolar), CA4.86L Primer (concentration: 10 micromolar)

Component Volume for 14 reactions(+5% error)
Water 132.3 micoleters
2x mytaq mix 183.75 micoleters
CA4.86R Primer (concentration: 10 micromolar) 14.7 micoleters
CA4.86L Primer (concentration: 10 micromolar) 14.7 micoleters

24 micoleters of this master mix was added to 14 tubes For the 2 negative controls 12.5 micoleters water and 12.5 micoleters mytaq mix were added E1 was used as a positive control

1 microleter of the DNA samples was added to the coresponding tube

The samples were then placed in the thermocycler set to

Step Temperature Duration cycles
1 92°C 3:00 1
2 92°C 0:30 35
3 50°C 1:00 35
4 72°C 0:15 35
5 72°C 2:00 1
6 4°C hold -

these amplified DNA samples were then tested by making a gel

to create the Gel the following steps were taken

2g agarose and 100ml 1X TAE buffer were mixed to make a 2% agarose 100ml gel mix the mix was microwaved and swirled until there were no flakes then 1 microliters Gelgreen was added

the mix was left to cool for 5 minutes then poured into the gel mold the gel was left to harden for 30 minutes

once hardened enough Used TAE buffer was poured into the gel box to cover the mold

5 microliter aliquots of DNA samples E27 E82 E29 E30 E31 E32 E33 E34 E35 E36 E37 E40 and the two controls were made 1 microliter of 5x loading dye was added to each

First 3 microliters of the HyperLadder 100bp was added to the first well of the mold then the DNA samples were each added to the wells in the following order

Ladder E27 E28 E29 Negative Control E30 E31 E32 Positive Control (E1)
Ladder E33 E34 E35 Negative Control E36 E37 E38 Positive Control (E1)

The voltage was set to 100V and run for 60 minutes

This is the resulting Gel

Notes

Many of these had multiple bands show up meaning somthing else was amplified from the sample. further tests will try to eliminate that band

Originally the bottom bands were thought to be in the right place while the top bands were not the correct amplification However after doing more PCRs is was reaized that it was the other way around. This also cleared up the mystery of why it seemed like E30 E34 E35 E36 and E37 were working when they usually do not show up in PCRs

some of these should be tested agian to confirm this conclusion s correct.
