  • Patent number: 6806047
    Abstract: Methods and compounds are provided for detecting target molecules in a sample using specific binding assays. In particular, methods are provided for detecting a nucleic acid target in a sample. In one embodiment, the method comprises hybridizing a nucleic acid target, comprising a target nucleic acid sequence, to a nucleic acid probe, comprising a probe nucleic acid sequence, wherein the target comprises a binding ligand. The hydridized target is contacted with a receptor comprising multiple sites capable of binding the binding ligand to complex the receptor to the binding ligand, and the receptor is contacted with an amplification reagent, comprising a plurality of the binding ligands, to complex the amplification reagent to the receptor. The presence of the complexed amplification reagent then is detected, for example, by detecting the presence of a detectable label, such as a fluorescent label, for example, on the receptor or the amplification reagent.

  • Publication number: 20030062067
    Abstract: This invention provides an apparatus and method for washing a biological chip cartridge. A washing station comprises a cartridge holder that includes at least two cartridge mounting tubes that are structured to retain the biological chip cartridge on the washing station without doors. At least one fluid source communicates with one of the mounting tubes and a waste dump communicates with another mounting tube. A fluid controller controls delivery of a fluid from the fluid source to the mounting tube.
