Bisulfite Conversion

Sodium bisulfite conversion of genomic DNA to differentiate and detect unmethylated versus methylated cytosines is the gold standard for DNA methylation analysis It provides single nucleotide resolution map of 5-mC of the genome (1) Bisulfite conversion involves the deamination of unmodified cytosines to uracil leaving the modified bases 5-mC and 5-hmC This procedure can then be followed

potassium metabisulfate vs sodium metabisulfate

Sodium metabisulfite is 67% available SO2 and potassium metabisulfite is 58% (available SO2) Of course that assumes pure chemical which neither ever is You're doing well to get 50% out of the potassium salt even from freshly purchased stuff because it is so reactive to oxygen in the air - especially in high humidity conditions That's why the pros recommend buying it fresh every year
