Figure 4From: Chitotriosidase - a putative biomarker for sporadic amyotrophic lateral sclerosisA schematic representation of the procedural steps for mass spectrometric analysis. Pooled CSF samples were subjected to mass spectrometry after sequential treatment procedures like, depletion of abundant proteins, tryptic digestion, iTRAQ labelling and SCX. Selected molecules were validated using ELISA.Back to article page
