Binding of anti-PspA fragments antibodies to the pneumococcal surface with 3 different PspA clades. Sera from immunized mice with recombinant PspA4ABC and PspAB1-5 were analysed by ELISA against pneumococcus strains with PspA fragments from clade 1 (ATCC 49619), clade 2 (ATCC 6305) and clade 5 (ATCC 700678). Non-immunized mouse serum was used as negative control.
