Fig. 4From: MALDI-TOF MS monitoring of PBMC activation status in sepsisHierarchical clustering of activated PBMCs. PBMCs were stimulated with different agonists for 18 h. The results are shown as hierarchical clustering. Vertical axis refers to the m/z ratio. Spectra are classified according to the presence/absence of peaks. PBMCs stimulated with LPS from Escherichia coli are presented in yellow, with Pseudomonas aeruginosa (P.a) in red, Escherichia coli (E.c) in orange, CpG ODN in dark green, PGN in green, Staphylococcus aureus (S.a) in blue, Streptococcus agalactiae (S.ag) in turquoise, unstimulated PBMCs in purple and PBMCs stimulated with poly I:C in dark blueBack to article page
