  • Publication number: 20190195881
    Abstract: A highly sensitive method of detecting GASP-1 or a fragment thereof in a sample is provided. The method comprises (a) exposing a surface to a sample comprising GASP-1 or a fragment thereof; (b) immobilizing an anti-GASP-1 antibody to the surface in the presence of the GASP-1 or a fragment thereof; (c) measuring the amount of the anti-GASP-1 antibody immobilized to the surface; and (d) determining the presence of the GASP-1 or a fragment thereof in the sample based on the amount of the anti-GASP-1 antibody immobilized to the surface. A coating agent may be immobilized to the surface in step (a), and the anti-GASP-1 antibody may be immobilized to the surface via the coating agent. The coating agent may be selected from the group consisting of a conjugate of bovine serum albumin (BSA) and a GASP-1 peptide (BSA-GASP-1 conjugate) a capture antibody against a microvesicle or exosomal surface biomarker, and a combination thereof. Also provided are kits for detecting GASP-1 or its fragment.

  • Patent number: 7853484
    Abstract: The present invention provides an auction method and system, that is, a seller proposes an expected selling price of an item in a tender offered by the seller and the item is announced and bid on the auction system provided by the manager of auction system, and a end time and a number of bids are set. Many buyers make bids by haggling the price down and a certain tendered bid with every bid is paid, and a bid-winner is a buyer who makes a “lowest price” and “only one” bid when the tender is concluded. The bid-winner is satisfied by buying the item at a low price, the selling price of the item offered by the seller and a commission of the auction system manager are obtained from total tendered bids of total bids and a bidding price by the bid-winner to satisfy three parties, such as the bid-winner, seller and auction system manager.
