  • Patent number: 7736910
    Abstract: The present invention comprises novel “one-step” methods for the production of gold sol and gold sol conjugates. The methods disclosed herein produce gold sol and colloidal gold conjugates with product with yields on the order of about 20 ODs. Since current methods in the art yield conjugates at concentrations on the order of about 2 ODs, the present invention represents an approximately 10-fold increase in production over conventional methods. The novel method provided herein also does not result in the production of undesired aggregate by-products that, in conventional methods, must be removed via centrifugation, filtration or other means. The new method is therefore less labor intensive and requires less time to complete than standard methods in the art for synthesizing pure colloidal gold conjugates.

  • Patent number: 7344893
    Abstract: A chromatographic lateral-flow assay system for rapid, high sensitivity method of detecting low levels of ligands in body fluids, with few false positives and few false negatives. The lateral-flow assay may have a membrane strip in ribbon form, which increases detection on the order of 2 to 10 fold over the conventional chromatographic specific binding assay techniques by placing a dried or lyophilized conjugate in colloidal spheres opposite side of the lateral flow membrane strip. A chromatographic specific binding assay strip device, comprising: a laminate strip having a first side and an opposite second side; a conjugate pad or membrane disposed on said first side of said laminate; a sample receiving pad or membrane strip and reservoir pad or membrane disposed on said second side of said laminate; and a detection pad or membrane strip disposed between the sample pad or membrane and the reservoir pad or membrane on said second side of said laminate.
