Abstract

The invention discloses a vitamin B5 (VB5, (R)-N-(3,3-dimethyl-2,4-dyhydroxy-1-oxobutyl)-3-calcium alanine) conjugate. The vitamin B5 conjugate is formed by coupling vitamin B5 hapten and keyhole limpet hemocyanin (KLH) which generates immunogenicity and is a carrier material, wherein n refers to number of molecules, of VB5, combined with one keyhole limpet hemocyanin molecule and is an integer, KLH refers to keyhole limpet hemocyanin, and molecular weight ranges from 450KDa to 1300KDa. The invention further discloses a preparation method of the vitamin B5 conjugate. The preparation method includes: connecting vitamin B5 with the carrier material generating immunogenicity to form the coupling material capable of inducing an animal immune system to generate antibodies. The preparation method has the advantages of convenience, quickness, specificity and accuracy. A wide application space is provided for using the coupling material to manufacture an enzyme-linked immunosorbent assay reagent box of VB5.
