WR304 mAb-biotinylated - AVANTI POLAR LIPIDS - 330022S

WR304 is an antibody that binds specifically to the lipids PIP and PIP2. WR304 also neutralizes infectious HIV-1 virus and can be used to probe the presence of PIP and PIP₂ in membranes in a variety of applications including inositol phosphate-dependent cell signaling pathways.

WR304-Biotin allows this antibody to be used in combination with a wide range of commercially available streptavidin-fluorophore and streptavidin-enzyme complexes. WR304-Biotin can also be used with samples that contain mouse IgM.

This antibody was developed by the Walter Reed Army Institute of Research (WRAIR) using a targeted adjuvant protocol with liposomes containing Avanti’s Lipid A.
