Albumin vides at formidle endothelial transcytose af plasmabestanddele og in vitro undersøgelser har vist, at tilstedeværelsen af albumin øger transporten af paclitaxel gennem endotheliale celler.
Albumin is known to mediate endothelial transcytosis of plasma constituents and in vitro studies demonstrated that the presence of albumin enhances transport of paclitaxel across endothelial cells.
