ABSTRACT

Objective:

Establish and validation of combined detecting of CCL18, CXCL1, C1D, TM4SF1, FXR1, TIZ suspension array technology.

Methods:

(1)CCL18, CXCL1 monoclonal antibody and C1D, TM4SF1, FXR1, TIZ protein were coupled with polyethylene microspheres. Biotinylated CCL18, CXCL1 polyclonal antibody and sheep anti-human IgG polyclonal antibody were prepared simultaneously. The best packaged concentrations of CCL18, CXCL1 monoclonal antibody and C1D, TM4SF1, FXR1, TIZ antigens were optimized. The best packaged concentrations of CCL18, CXCL1 polyclonal antibodys and C1D, TM4SF1, FXR1, TIZ sheep anti-human IgG polyclonal antibody were optimized to establish a stable detected suspension array.(2)Sixty patients confirmed by pathological examination with ovarian cancer(ovarian cancer group)which treated in Affiliated Tumor Hospital of Guangxi Medical University, 30 patients with ovarian benign tumor(benign group)and 30 cases of healthy women(control group)were chosen between September 2003 and December 2003. Suspension array technology and ELISA method were used to detect expression of CCL18, CXCL1 antigen and C1D, TM4SF1, FXR1 and TIZ IgG autoantibody contented in 3 groups of serum, then to compare the diagnostic efficiency and diagnostic accuracy of two methods(coefficient of variation between batch and batch).

Results:

(1)This research successfully established stable detecting system of CCL18, CXCL1, C1D, TM4SF1, FXR1 and TIZ IgG autoantibody. The best concentration of CCL18, CXCL1 monoclonal antibody and C1D, TM4SF1, FXR1, TIZ antigen package were 8, 8, 12, 8, 4 and 8 µg/ml; the best detection of CCL18, CXCL1 biotin polyclonal antibody and C1D, TM4SF1, FXR1, TIZ sheep anti-huamne IgG polyclonal antibody were respectively 4, 2, 2, 4, 4 and 2 µg/ml.(2)Suspension array technology and ELISA method were used to detect CCL18, CXCL1 antigen and C1D, TM4SF1, FXR1, TIZ IgG autoantibody of three groups in serum were similar(P>0.05).(3)The comparison of two methods in the diagnosis of efficiency the diagnostic accuracy of two methods were 99.2%(119/120)and 94.2%(113/120), the difference was statistically significant(P=0.031). The sensitivity of the diagnosis of ovarian cancer of two methods were 100.0%(60/60)and 93.3%(56/60), specific degrees were 100.0%(59/59)and 93.4%(57/61), positive predictive value was 100.0%(60/60)and 93.3%(56/60), negative predictive value was 98.3%(59/60)and 95.0%(57/60), the difference was statistically significant(P<0.05).(4)The detected results of CCL18, CXCL1 antigen and C1D, TM4SF1, FXR1, TIZ IgG autoantibody shown that the diagnostic accuracy of suspension array technology was superior to those of ELISA method(all P<0.05).

Conclusion:

The study has established the stable detection of suspension array technology, and the diagnostic efficiency and diagnostic accuracy was much better than that by ELISA.
