摘要:
Methods of mitigating the risk of rejection of an allograft or xenograft in an incompatible recipient by neutralizing one or more populations of circulating antibody cross-reactive with a carbohydrate antigen expressed by the allograft or xenograft. The method includes administering to the recipient by intravenous infusion a concentration of a synthetic antigen lipid construct sufficient to neutralize the one or more populations of circulating antibody in the recipient.
摘要:
Method of incorporating a water soluble construct of the structure L-S-F into the lipid bi-layer of cells by contacting a suspension of the cells with a solution of the construct at a concentration and for a time and temperature sufficient to allow the construct to insert into the lipid bi-layer. In the structure L-S-F, F is a peptide, S is a spacer containing an oligomer of ethylene glycol covalently linking F to L and the number of ethylene oxide repeats in the oligomer of ethylene glycol is 6 to 14, and L is a phosphatidylethanolamine.
摘要:
The invention relates to functional lipid constructs and their use in diagnostic and therapeutic applications, including serodiagnosis, where the functional moiety is carbohydrate, peptide, chemically reactive group, conjugator or fluorophore.
摘要:
Methods of treating an inert surface of a substrate to improve the adherence to the treated surface of micro-dimensioned particles including the steps of: contacting the inert surface with in an aqueous dispersion of a construct of the structure F-S-L; and then washing the surface with an aqueous vehicle to provide the treated surface, where F is a polyamine; S is —CO(CH2)2CO—, —CO(CH2)3CO—, —CO(CH2)4CO— or —CO(CH2)5CO—; and L is a diacyl- or dialkyl-glycerophospholipid.
摘要:
The invention relates to methods for effecting qualitative and quantitative changes in the functional moieties expressed at the surface of cells and multi-cellular structures, and functional lipid constructs for use in such methods. In particular, the invention relates to functional lipid constructs and their use in diagnostic and therapeutic applications, including serodiagnosis, where the functional moiety is a carbohydrate, peptide, chemically reactive group, conjugator or fluorophore.
摘要:
Biocompatible methods of functionalizing inert surfaces for use in biological applications are described. The methods employ the use of synthetic constructs of the generic structure F-S-L (where F is a functional moiety, S is a spacer selected to provide a construct that is dispersible in water, and L is a diacyl- or dialkyl-glycerophospholipid). An object of the invention is to localize or immobilize functional moieties to the inert surface of a substrate wherein the surface is comprised of glass, silver, polyamide, polycarbonate, polypropylene, polyethersulfone, polytetrafluoroethylene or polyvinylidene fluoride, and the substrate is comprised of a fiber, membrane, microsphere or nanosphere.
