Figure 4From: The discovery and identification of a candidate proteomic biomarker of active tuberculosis MALDI-TOF MS spectra of the potential peptide biomarker containing fraction. Serum samples from TB patients were used for the purification of the up-regulated peptide biomarker (mass/charge 2554.6) using HPLC. The purified fraction contains the target peptide (2554.6) and four other peptides peaks (2467.5, 2770.1, 2846.5 and 2933.3).Back to article page
