Fig. 4From: Characterization and optimization of the haemozoin-like crystal (HLC) assay to determine Hz inhibiting effects of anti-malarial compoundsFTIR spectra of haemin, sHz and HLC. Fourier Transform Infrared spectroscopy: Haemin (a), synthetic Hz also called β–Haematin (b); and Hemozoin-Like Crystals (HLC) (c). Vertical arrows indicate typical bands associated with sHz and nHz, which are practically absent in the spectrum of HLCBack to article page
