CLS-PEG-NH2 is one of the reactive cholesterol PEG derivatives with primary amine group. Cholesterol is an essential lipid component for the establishment and maintenance of basic animal cell functions. It is one of the components of animal cell membrane structure, which can establish appropriate membrane permeability and fluidity in animal cells. In addition to its structure and function, cholesterol is an important precursor for the biosynthesis of steroid hormones, bile acids and vitamin D. Cholesterol is a hydrophobic molecule with low water solubility. Amine functional peg cholesterol derivatives can react with many amine reactive functional groups (such as NHS esters, aldehydes, etc.).

Handling and use:

CLS-PEG-NH2 Sensitive to light and temperature. For optimum use, the material should always be kept at low temperature under dry conditions. Avoid frequent thawing and freezing.

Storage conditions:

CLS-PEG-MAL It needs to be stored at - 20 ℃ in dry condition under inert gas protection. One year later, it was retested.
