sodium bisulphite

Bleaching by reduction using chemicals such as sodium bisulphite.

Aldehydes characteristically form "addition compounds" with sodium bisulphite:

Three common reducing bleaches are sodium bisulphite, sodium hydrosulphite and titanium stripper.

Further, bisulfite treatment also causes DNA degradation and requires an additional purification step to remove the sodium bisulphite (Laird 2010).

Removal can be effected by the addition of sodium bisulphite, but the source of the chlorine should be located and stopped, so that the trouble does not persist.

Subsequent amplification and sequencing of untreated DNA and sodium bisulphite treated DNA allows for methylated sites to be identified.

Methylation Specific PCR (MSP) Genomic DNA was treated with sodium bisulphite as previously described [ 33 ] .
