Outline of Final Research Achievements

Addition of original anti-myristoylation antibody reduced precipitation of myristoylated HIV-Nef in the presence of lipid micelle, and this result indicates inhibitory effect of the antibody restraining interaction between myristoylated molecules and lipid membranes.
Next, anti HIV-Nef antibody with capacities of high specificity and low dissociation constant (10^-9) was developed by original antibody library technique.
A diabody was constructed by a fusion of the antibody with the anti- myristoylation antibody. Addition of the diabody preliminary reduced precipitation of myristoylated HIV-Nef in the presence of lipid micelle again. The remaining subject is specificity of the diabody to myristoylated proteins in the cells.
