An improved single-step lysis protocol to measure luciferase bioluminescence in Plasmodium falciparum

Abstract

This report describes the optimization and evaluation of a simple single-step lysis protocol to measure luciferase bioluminescence from genetically modified Plasmodium falciparum. This protocol utilizes a modified commercial buffer to improve speed of assay and consistency in the bioluminescence signal measured by reducing the manipulation steps required to release the cytoplasmic fraction. The utility of this improved assay protocol is demonstrated in typical assays that explore absolute and temporal gene expression activity. © 2012 Hasenkamp et al; licensee BioMed Central Ltd.
