Description

DSPE-PEG2000-Cy5.5 is a phospholipid-fluorophore conjugate consisting of Cy5.5 covalently linked to 1,2-distearoyl-sn-glycero-3-phosphoethanolamine (DSPE), serving as a surface label for liposomes in multimodal CT/optical imaging.DSPE-PEG2000-Cy5.5 can be used for the research of non-small cell lung cancer[1].

In Vitro

DSPE-PEG2000-Cy5.5 (6.5 mM lipid concentration in FBS; 96 h at 37°C) containing liposomes release less than 25% of their Cy5.5 content over 96 hours of incubation at 37°C in fetal bovine serum[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

The DSPE-PEG2000-Cy5.5-containing liposomes (1.8 g lipid/kg body weight; tail vein; single injection) exhibit a prolonged vascular half-life of 36.2 hours in non-tumor-bearing mice, with significantly higher accumulation in the liver and kidneys at select time points compared to CT-only liposomes[1].

Animal Model: CD-1 (athymic female, 6 weeks old, average weight 27 g)[1]
Dosage: 1.8 g lipid/kg body weight (containing DSPE-PEG2000-Cy5.5 at a molar ratio of 0.02 relative to total lipids)
Administration: tail vein; single injection
Result: Exhibited a vascular half-life of 36.2 hours.
Showed statistically significant higher accumulation in the liver at 5 minutes and 24 hours postinjection compared to CT-only liposomes.
Showed statistically significant higher accumulation in the kidneys at 48, 72, and 96 hours postinjection compared to CT-only liposomes.
Had accumulation in the spleen equivalent to CT-only liposomes.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
