Hox11-null and splenectomized mice do not respond to vaccination with streptococcal polysaccharides. Pneumovax® 23 was injected subcutaneously, intramuscularly, intraperitoneally, or intravenously into either (A) C57BL/6 and Hox11-null mice or (B) sham-operated and splenectomized mice. Specific IgM antibodies in sera were measured by ELISA before and 6 d after immunization. The optical density (OD405) measured with a 1:80 serum dilution is shown. Each data point indicates the relative antibody level of a single mouse.
