Composition and immuno-stimulatory properties of extracellular DNA from mouse gut flora

Figure 1 Mucus layer and eDNA in the mouse small intestine and colon. The first two columns are images obtained by optical microscopy with AB-PAS staining, and the third one are images obtained by laser scanning confocal microscopy with TOTO-1 staining. Pictures from the first two rows are the colon mucus layer, while those of the third row are the small intestinal mucus layer. A-F: Colon; G-I: Small intestine; A, D, G: AB-PAS 10×; B, E, H: AB-PAS 40×; C, F, I: TOTO-1 10 ×.
