    摘要: Improved process for preparing 1,2-diacyl-3-glycerylphosphorylcholines, wherein the diacyl groups are, different or the same, a residue of a saturated or unsaturated fatty acid, particularly one of the acyl groups being a residue of a highly unsaturated fatty acid or being a residue of a saturated or unsaturated fatty acid labelled with an isotope, which comprises acylating a glyceryl-phosphorylcholine or monoacyl derivative thereof or the salt thereof with an acylating agent (e.g. 1-acylimidazole or 4-acyl-3-phenyl-1,2,4-oxadiazol-5-one) in the presence of a catalyst (e.g. an alkali salt of a nitrogen-containing 5-membered heterocyclic compound or sodium oxide).

    摘要: An enzyme immunoassay for an antigen using a solid phase, which employs (a) a biotinylated antibody in which a biotin derivative is bound to a thiol group of an Fab' fragment of an antibody, (b) an enzyme-labelled antibody, and (c) a solid phase immobilized with a substance capable of specifically reacting with the above biotin derivative selected from the group consisting of avidin, streptoavidin and a derivative thereof which is bound to the solid phase directly or via a linkage between another biotin derivative and a high molecular weight substance bound to the solid phase, or alternatively employs (a') a solid phase immobilized with a biotinylated antibody via a substance selected from the group consisting of avidin, streptoavidin and a derivative thereof wherein said substance is bound to the biotin moiety of said biotinylated antibody and is also bound to the solid phase directly or via a linkage between another biotin derivative and a high molecular weight substance bound to the solid phase, and (b') an enzyme-labelled antibody, and a solid phase used therefor.
