Patent number: 9857365Abstract: Described are immunoassay kits having a conjugate structure separate from an immunochromatographic strip in which the conjugate structure is freeze-dried with uniform droplet size, and related compositions and methods. The unique structure of the kits described here permits sample containing analyte to be reacted uniformly with the conjugate structure before being subjected to immunochromatography by application to the strip. This results in improved performance of the assay. In addition, the freeze-dried conjugate structure can be stored without contamination and is easy to carry. In addition, the freeze-dried conjugate structure can be rapidly and uniformly dissolved so that it is immediately allowed to react with a mixture of a buffer and a sample, the reaction product then being analyzed by immunochromatography, making it suitable for use in point-of-care testing.Type: GrantFiled: May 31, 2013Date of Patent: January 2, 2018Assignee: SD Biosensor, Inc.Inventors: Hyoung Gil Choi, Sung Yub Hong, Hee Young Hwang, Hyo Keun Lee

Publication number: 20150160203Abstract: The present invention relates to a freeze-dried conjugate structure for immunochromatography, an immunoassay kit comprising the freeze-dried conjugate structure and an immunochromatographic strip, and a method for qualitatively or quantitatively analyzing an analyte in a sample using the immunoassay kit. Because a sample is subjected to immunochromatography after reacting uniformly with a freeze-dried conjugate structure separately prepared according to the present invention externally, quantitative analysis can be performed with high reproducibility and linearity depending on a concentration compared to a conventional assay method which is performed using an immunochromatographic strip comprising a conjugate pad prepared by adsorbing a conjugate. In addition, the freeze-dried conjugate structure of the present invention can be provided in a state in which it is received in a chamber additionally comprising a cap. Thus, it can be stored without contamination and is easy to carry.Type: ApplicationFiled: May 31, 2013Publication date: June 11, 2015Inventors: Hyoung Gil Choi, Sung Yub Hong, Hee Young Hwang, Hyo Keun Lee
