1,2-Dipalmitoyl-sn-glycero-3-PE-N-(capbiotin) is a biotinylated phospholipid. It has been used in PEGylated polyamidoamine-dendrimer-conjugated supported lipid bilayers (SLB) to isolate circulating tumor cells and tumor cell microembolis from patient-derived blood by antibody-coated microfluidics. [1] It has also been used as a component of SLBs to detect protein-ligand binding with ortho-conjugated Texas Red DHPE. [2] In addition, 1,2-dipalmitoyl-sn-glycero-3-PE-N-(capbiotin) has been used in SLBs partitioned into nanowells to create DNA curtains, which can be used as a high-throughput tool for detection of protein-DNA interactions at the single molecule level.[3]
