The water rinse represents a major departure-from the conventional single dip in sodium bisulfite solution.
The DNA methylation status of the promoters of interest can be detected directly via such methods as methylation-sensitive restriction analysis (15), but the most commonly used techniques rely on chemically treating target DNA with sodium bisulfite.
First, read all ingredient labels for any of six sulfites: sulfur dioxide, sodium sulfite, sodium bisulfite, potassium bisulfite, sodium metabisulfite, potassium metabisulfite; sometimes they are listed simply as "sulfiting agent.
The clarified water flows over the effluent weirs and discharges to the excess flow chlorine contact basin, where the flow is disinfected by sodium hypochlorite and dechlorinated with sodium bisulfite.
Sub-lot 1: Sodium bisulfite 40% - sub-lot 2: 35% active hydrogen peroxide with stabilizer - sub-lot 3: Acetic acid 75-80% - sub-lot 4: Sodium hypochlorite 47/50 chlorometric degrees - sub-lot 5: Oxalic acid.
has been widely used for sodium bisulfite modification, and a variety of commercial kits are available for this purpose (3).
Following disinfection, the water is [TABULAR DATA FOR TABLE 1 OMITTED] dechlorinated using sodium bisulfite, and previously sulfur dioxide, to meet the plant's chlorine residual discharge limit of zero.

Most of these methods include DNA extraction followed by sodium bisulfite conversion (14) of the denatured template DNA.
One chemical feeder is located in a room adjacent to the sodium bisulfite solution storage room.
