  • Sodium bisulfite is often used in laboratories to preserve biological samples.
  • sodium bisulfite
  • bisulfite conversion
  • bisulfite-treated DNA

Examples

  • In brief, DNA samples were first bisulfite converted using the EZ-96 DNA Methylation Gold Kit (Zymo Research, Irvine, CA, USA).

  • Therefore, this would also minimize the feed rate and the cost of the dechlorination chemical (sodium bisulfite).

    Academic text (1998)
  • A standard system using sodium bisulfite was a possibility, but there were still several other factors to consider.

    Academic text (1998)
  • Both systems included the required flow pacing and residual trim control we desired for controlling the chlorine and sodium bisulfite feed rates.

    Academic text (1998)
  • Extensive cleaning of the membranes with bisulfite, citric acid, and hydrogen peroxide was required to restore membrane efficiency in the County's plant.

    Academic text (2001)
  • The lack of correlation between pausing index and pausing stability was recently demonstrated using methylation footprinting with whole genome bisulfite sequencing.

    Academic text (2018)
  • 200-600 ng of genomic DNA was used in the bisulfite conversion reaction (EZ DNA Methylation kit; Zymo Research).

    Academic text (2017)
  • When treating drinking water, the addition of bisulfite effectively removes chlorine.

  • In food processing, bisulfite acts as a preservative to prevent browning in fruits.

bisulfite singular
bisulfites plural

Morphology

bisulfite = sulfite (semi-transparent) = bis + sulfite

Formally analyzable as 'bis-' + 'sulfite', but the precise chemical implication and ion identity require specialized chemistry knowledge and may not be inferable by general learners.

Etymology

The word bisulfite comes from the parts bi- and sulfite. In chemistry bi- often shows a hydrogen is attached and sulfite comes from 'sulfur', so bisulfite is the hydrogen form of a sulfur ion that is used to preserve and protect foods and chemicals.
