DSPE-PEG400-DBCO
DSPE-PEG400-DBCO is a phospholipid PEG polymer that combines a hydrophobic phospholipid (DSPE), a hydrophilic polyethylene glycol spacer with a molecular weight of 400 Da, and a reactive click chemistry terminal group (DBCO). DSPE-PEG-DBCO migrates to lymph nodes via the endogenous albumin transport system, implants bioorthogonal DBCO docking sites, and enables the enrichment of azide-functionalized vesicles in lymph nodes mediated by click chemistry. DSPE-PEG-DBCO can be used in studies related to atherosclerosis.

Description
In Vitro
DSPE-PEG2000-DBCO can be designed as the first dose (pretargeting anchor) of the two-component sonodynamic vaccine SenoVac: it efficiently migrates into lymph nodes via hitchhiking on endogenous albumin, pre-installs bioorthogonal DBCO docking sites in lymph nodes, and specifically and durably locks the azide-modified SCAV in lymph nodes through copper-free click chemistry when the second dose arrives[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
DSPE-PEG2000-DBCO (s.c.; single dose) achieves effective and sustained lymph node labeling, with fluorescence peaking at 24 hours and remaining detectable for up to 120 hours[1].
DSPE-PEG2000-DBCO (s.c.; administered prior to each vaccination dose) as part of the SenoVac platform reduces plaque senescent cell burden and attenuates atherosclerosis progression in high-fat diet-fed ApoE-/- mice[1].
DSPE-PEG2000-DBCO (s.c.; administered prior to N3-SCAVᴴᴿ) as part of the SenoVac platform reduces senescent cell burden across multiple organs in p16-tdTomato reporter mice, with efficacy enhanced by ultrasound stimulation[1].

Result:Exhibited approximately threefold higher lymph node fluorescence than DSPE-PEG-pretreated controls.
Showed strong fluorescence localized predominantly in draining lymph nodes, with moderate liver uptake and minimal signal in heart, spleen, lung, and kidney.
