The molecules can be labeled in the aqueous phase without organic solvents. Therefore, the product is especially suitable for labeling proteins that are easily denatured in the organic phase and proteins with low solubility. 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.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
