DOPE-PEG is a versatile phospholipid derivative with unique properties that make it suitable for various applications. Its hydrophobic and hydrophilic nature enables efficient encapsulation and delivery of drugs and nucleic acids, making it a valuable tool in drug delivery systems and gene therapy. Additionally, DOPE-PEG can enhance the stability and circulation time of liposomes, improving their efficacy as drug carriers. Cy7 emits at 750 nm and has a maximum absorption peak at about 773 nm. Cyanine dye is often used in biomolecular labeling, fluorescence imaging and other fluorescent biological analysis, and Cy7-labeled PEG derivatives can be used to track biomolecules due to their strong red light fluorescence.

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.
