Description

General description

Sodium dodecyl sulphate (SDS) is an anionic surfactant. It is also called as lauryl sulphate.

Application

Sodium dodecyl sulphate (SDS) has been used:

• in the characterization of Enterobacteriaceae strain based on sensitivity to selective compounds
• to treat human skin in vitro and in vivo to evaluate the role of nuclear localization of 27-kDa heat shock protein (HSP27) in potential skin irritation
• in the decellularization of porcine heart valve tissue
• to treat sperm for in vitro induction of sperm decondensation

Anionic detergent

Packaging

1 kg in poly drum

10, 25, 100, 250, 500 g in poly bottle

Biochem/physiol Actions

Sodium dodecyl sulphate (SDS) helps to quickly disrupt the biological membranes. It is usually used as one of the major constituent of several reagents, that are used to purify nucleic acids. SDS can block the activity of RNase and deoxyribonuclease (DNase).
