Naturally occurring antibodies against related C-terminal regions of the MSP3 family of proteins exhibit cross-reactivity.

Antibodies affinity-purified against C-terminal recombinant protein from each member of MSP3-family of proteins were assessed for their cross-reactivity towards other members by ELISA. O.D.450 values obtained for the reactivity of affinity-purified antibodies towards each recombinant protein are shown. The shaded boxes represent reactivity of the antibodies affinity-purified against their respective recombinant proteins, which was considered to be 100%. The degree of cross-reactivity towards other members of the family is expressed as fractions of 100%, shown in bold.
