(a) Structure illustration of micro column, standard valve and sieve valve; (b) photograph of the microfluidic chip.
ELISA reactivity of sera from patients against C-Igl. ELISA plate was coated with 100 ng per well of C-Igl. Serum samples from patients and healthy controls were used at 1:400 dilutions. The dashed line indicates the cut-off value. Data are representative of results from three independent experiments.
Schematic representation of the ELISA in the chip.
ELISA on the chip. The signals were collected by CCD of microscope. A: negative sample; B and C: positive samples.
