  • Patent number: 9469868
    Abstract: Methods and compositions which can be used to increase the strength and/or probability of forming a binding complex comprising a target molecule and a substrate are disclosed. In one aspect, linking molecules having one or more members of a reactive pair are disclosed which can be used to increase the number of intra-complex binding interactions in a complex comprising a target molecule and a substrate. Intra-complex crosslinking and inter-complex crosslinking can be utilized in connection with these methods and compositions to further strengthen and stabilize the disclosed binding complexes.

  • Publication number: 20160258938
    Abstract: Methods of detecting a target analyte in a sample are provided. Aspects of the method include: (a) contacting the sample with (i) a first capture agent that specifically binds the target analyte and (ii) a reporter complex under conditions sufficient to produce a sandwich complex; (b) separating the sandwich complex from the sample; and (c) releasing a detectable tag from the sandwich complex. The reporter complex may include a first specific binding member linked to a second capture agent that specifically binds the target analyte, and a second specific binding member specifically bound to the first specific binding member. In some cases, the second specific binding member is linked to a detectable tag. The releasing step may be achieved using a displacement binding member that is complementary to the first or second specific binding member. Also provided are compositions, systems and kits for practicing the subject methods.
