A chemical used to clean and break up proteins in labs
  • noun
  • /ˌɛsˌdiːˈɛs/
  • Specialized

  • In the lab, we used SDS to denature the proteins for analysis.
  • age-adjusted SDS

Examples

  • The proteins retained on the beads were analyzed by SDS-PAGE and western blotting. Microtubule binding assay in fixed COS7 cells.

    Academic text (2016)

  • OK, and then you run the SDS page separation.

  • All SDS calculations were adjusted for gestational age at birth.

    Academic text (2014)

  • A much more complete elution of bound proteins is achieved by elution with 2% SDS and subsequent precipitation with 80% acetone.

  • Age- and gender-specific SDS for weight and body length measurements were calculated by comparison to UK normative data (Freeman et al. 1995).

    Academic text (2014)

  • 30-50 g of protein per lane were separated on 4%-12% SDS-PAGE and transferred to a PVDF membrane (Millipore).

    Academic text (2017)

  • Both the flow-through and eluent were subjected to SDS-PAGE, and the protein bands were then excised, sliced into pieces, and digested via an in-gel digestion method.

    Academic text (2018)

  • The results of the experiment were examined using SDS-PAGE to visualize the protein bands.

  • Researchers often employ SDS in biochemical applications to disrupt cellular structures.

Morphology

SDS = sodium + dodecyl + sulfate (opaque) = S + D + S

Formation by initial letters (an initialism) is arbitrary for most learners and does not allow them to infer the meaning from the letters alone.

Etymology

SDS comes from the chemical name sodium dodecyl sulfate; sodium is like 'salt', dodecyl means a 'long oily chain', and sulfate is a 'sulfur salt', so the name explains why SDS works as a strong cleaner that helps break up oils and proteins.
