Primer Mixes
Primers are resuspended at 100 uM, so add 3x10 uL of the primers to 970uL of water to make the primer mixes:
- For WT Primers combine both RFLP primers with the WT-Lep-F primer
- For Ob Primers combine both RFLP primers with the Lebob-R primer
PCR Reaction
The PCR program is called ob-ob and is:
- 95 °C 2 min
- 40 cycles of:
- 95 °C 30 s
- 58 °C 30 s
- 72 °C 45 s
- 72 °C 7 min
Bands
There should be a control band in all lanes at 191bp For the wt primers if there is one or more wt alleles there should be a band at 104bp For the ob primers, if there is one or more ob alleles there should be a band at 123bp
