Figure 3. Linearity of LTIA.

Figure 3

Linearity tests for the GP73 were performed using LTIA with 3 monoclonal antibodies and polyclonal antibodies on a BECKMAN AU5400 analyzer, respectively. The standard curve was established using GP73 standard samples concentration from 1.5 to 640 ng/mL (a). The figure shows a very good linear response in the concentration range from 10–350 ng/mL for the 3 monoclonal antibodies and 20–320 ng/mL for the polyclonal antibodies, respectively (b).
