Abstract:

Immune colloidal gold technique has been received universal attention by the domestic and foreign researchers for its fast, accurate and simple characteristic. The main affect factors of the technique were analysised in this research， the materials and the methods for preparing and labelling the colloidal gold, coating the nitrocellulose filter, the preservation and stability detection for the end item. It is expected to provide the theory basis and the technology reference for preparing the production of the colloidal gold detection.
