The high hemeozoin (beta-hemeatin) content of Plasmodium falciparum lysates imposes severe
limitations on the analysis of the malarial proteome, in particular compromising the loading capacities
of two-dimensional gels. Here we report on the adaptation of a recently developed solution-phase
isoelectric focusing-based fractionation technique as a prefractionation strategy for efficient containment
of hemeoglobin-derived products and complexity reduction, to facilitate the high-resolution gel-based
quantitative analysis of plasmodial lysates.
