Cholesterol is an essential lipid component to build and maintain basic animal cell function. It is one of animal cell-membrane structure components and establishes proper membrane permeability and fluidity in animal cells. In addition to its structural function, cholesterol is also the important precursor for the biosynthesis of steroid hormones, bile acids and vitamin D. Cholesterol is a hydrophobic molecule with very low water solubility. Amine functional PEG cholesterol derivatives are able to react with a number of amine reactive functional groups such as NHS ester, aldehyde, etc. Cholesterol PEGs offered by ruixibio have good water solubility, flexible linker structure and diverse functionalities. Our Cholesterol PEG derivatives have been used successfully in cell membrane imaging, liposome formulation and drug delivery. As a leading PEG cholesterol provider, ruixibio now offers a variety of multifunctional PEG cholesterol molecules for different applications. Handling and Use: CLS-PEG-NH2  is sensitive to light and temperature. For best use, material should always be kept in low temperature in dry condition.  Avoid frequent thaw and freezing. For more information about using this product, .   Storage Conditions： CLS-PEG-NH2 should be stored at -20℃. Desiccate.  Materials may be handled under inert gas for best stability.
