The ESAT-6 Protein of Mycobacterium tuberculosis Interacts with Beta-2-Microglobulin (β2M) Affecting Antigen Presentation Function of Macrophage
Figure 9
Detection of ESAT-6:β2M complex in pleural fluid.
Pleural fluid samples from 7 pleural TB positive and 7 TB negative patients were subjected to sandwich ELISA. The amount of β2M (A) and ESAT-6:β2M complex (B) was measured and compared on the basis of absorbance at 492 nm between TB positive and TB negative patients.
