Figure 4. Semi-quantitative analysis of CXCL16 immunoreactivity in primary tumours (high and low grade) and urocystitis tissues in relation to the CXCL16 concentration found in the urine supernatant of these patients.

Staining of CXCL16 in patient tissue was categorized as absent, low, intermediate or strong according to method 1 (Table 3). Normalized CXCL16 concentrations in urine supernatant were compared to the immunoreactivity signal found in the matching tissues.
