Abstract:

α-1-Fetoprotein (AFP) is an important tumor marker for the diagnosis,and even early detection of original liver carcinoma. In clinical practice its determination is only performed with IRMA or spectrophotometric ELISA. In comparison with IRMA, the later is a more welcome procedure and has been widely used to, detect AFP. However, its sensitivity is inadequate in many assays due to the influence of specimen color and some experimental factors. This work uses a gold disk electrode (0.5 mm diameter) as working electrode and improves the sensitivity detecting AFP for about ten times.
