Figure 6. Sandwich ELISA Using mAb #1 and mAb #2.
(A) mAb #1 was labeled with HRP for detection and mAb #2 was used as the capture Ab. (B) The standard curve was generated using Hpt standard ranging from 0.005 - 10 μg/mL. The haptoglobin concentration in M-LAC material, lung cancer and matched control plasma sample were measured using this assay.
