Figure 4: TIMP1 concentrations in tumor fluids. TIMP1 concentrations observed in individual malignant tumor fluid samples (M1- M10) and in individual benign tumor fluid samples (B1-B10) using ELISA immunoassay. Mean TIMP1 concentration was significantly higher in malignant tumor fluid samples (182.23 ± 92.99 ng/mL) than in benign tumor fluid samples (78.69 ± 70.70 ng/mL) (p< 0.05). 90% of malignant tumor fluid samples have values above the average concentration of benign samples.
