Specificity and reproducibility of growth inhibition by PfMSP1-19 specific antibodies. PfMSP1-19 specific inhibitory rabbit antiserum was added at a 1 in 10 dilution in two cycle growth assays. Growth is expressed as a percentage of controls (sera from non-exposed Australian residents). Results are from 8 different experiments carried out between December 2005 and July 2007. Assays were performed in duplicate and values represent the mean + range.
