ABSTRACT:
The device has a transparent capillary assay tube attached at its upper end to a lateral portion of the support structure of the device. The lower free end of the assay tube is engageable with an absorbent material upon manual downward deflection of the support structure. The assay tube is filled through a funnel shaped aperture in the lateral portion of the device, and the tube is drained by engaging the lower free end of the tube with the absorbent material. By attaching appropriate antibody, antigen or hapten to the inner surface of the tube, immunoassays may be performed in the tube.
