A fused quartz capillary was taken as the carrier for the immunoassay of the tumor marker alpha fetal protein (AFP) as a model protein. The capture antibody of AFP was immobilized in capillary. Based on a sandwich immunoassay format, the antigen and corresponding horseradish peroxidase (HRP) labeled antibodies were introduced into the capillary for online incubation. After the injection of the chemiluminescence substrate, the chemiluminescence signals were captured by the CCD camera and changed into figures. The results could be read by gray level analysis of the figures. When the capture antibody was diluted 100 times, the enzyme labeled antibody was diluted 200 times, and the exposure time was 20 s, the detection range of AFP was 3.1-50 ng/mL and the critical concentrations of 20 ng/mL clinical applications were covered. The limit of detection was 2.7 ng/mL. Twenty clinical samples were tested with fine accuracy. The recoveries of the spiked samples were between 96.0% and 106.7%. In the assay, the sample consumption was low and the experimental material was simple and cheap. The method does not require large instruments, and is appropriate for clinical application
