Technical Support

Polyoxyl 40 stearate (PEG 40 stearate) is a nonionic surfactant formed by the esterification of stearic acid with polyethylene glycol (PEG) containing approximately 40 ethoxy units, it is widely used in pharmaceutical preparations, nanodrug carriers, emulsification systems and biomedical materials. Polyoxyl 40 stearate can serve as a matrix component of solid lipid nanoparticles to achieve controlled release of encapsulated antifungal drugs; it can also act as a base material for solid lipid nanoparticles for vaginal administration, and polymerizable groups can be introduced via modification with acryloyl chloride.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
