DNA Methylation sites in c-Fos promoter
Approximate MW:
38,337 daltons (unmethylated)
38,252 daltons (methylated)
each methylation site causes 15 dalton decrease in MW 
Rat c-fos Primers used by Alcala and Houpt
Primers designed with Primer 3 using the 300 bases upstream of c-Fos transcription start based on gi|62750806|ref|NC_005105.2|NC_005105 (equivalent to bases 172-471 of U02631, which claims start of 5’UTR is at 455.)
Forward at -261 (cFosSense-261):
- 5'-CCATCCCCGAAATCCTACAT-3'
Reverse at -6 (cFosAS-6):
- 5'-CAATCGCGGTTGGAGTAGTA-3'
Product size: 256 bp
PCR conditions for use with HotStarTaq mix (progam CFOSGENO on thermocycler)
