Reminder：

In order to obtain the best use effect of the product, the material should always be kept at a low temperature under dry conditions to avoid frequent thawing and freezing. 

To ensure the stability of the product, please note that the package can only be opened after constant temperature drying!

Polyethylene glycol phospholipid liposomes form high-quality materials, which can be used for drug delivery, gene transfection and vaccine delivery. Pegylated phospholipids can significantly improve blood circulation time and stabilize drug encapsulation. These materials can also be used for targeted drug delivery by modifying surface ligands such as antibodies and peptides. (DSPE) conjugated polyethylene glycol is a combination of phospholipids and polyethylene glycol, which has hydrophilicity and hydrophobicity. These materials can also be used for targeted drug delivery by modifying ligands with target surfaces, such as antibodies and peptides.

Cyanogen dye cyanine is often used in biomolecular labeling, fluorescence imaging and other fluorescent biological analysis. Cy5 (sulfo-cyanine5) is a reactive dye used to label amino groups of peptides, proteins and oligonucleotides. Excitation wavelength (nm): 649, emission wavelength (nm): 670。
