Beschreibung

Anwendung

Sodium dodecyl sulfate has been used:

• to dissolve insoluble purple formazan in 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay
• to perform SDS–PAGE of yeast tubulin
• as an additive in linolenic acid solution to assess the total antioxidative activity (TAA) of the bacteria using the linolenic acid test (LA-test)

Anionische Waschsubstanz

Biochem./physiol. Wirkung

Sodium dodecyl sulfate (SDS)/lauryl sulfate, an ionic detergent has the ability to distract biological membranes. It can block RNase and deoxyribonuclease (DNase) activity. SDS is one of the main constituents of several reagents, that are used to purify nucleic acids. It is also considered as a permeability enhancer in oral formulations.

Qualität

Predominantly (approx. 70%) C₁₂; lauryl sulfate, sodium salt; balance consists of higher homologs.
