Abstract: A construct is provided that is capable of binding a plurality of molecules, the construct comprising a first moiety with a first molecule binding region and a first molecule non-binding region; and a second moiety with a second molecule-binding region and a second molecule-non-binding region, whereby the first binding region and second binding region are at opposite ends of the construct. Also provided is a method for detecting protein having certain amino acid sequences, the method comprising supplying a collection of proteins each with unknown amino acid sequences, contacting the collection with a moiety having a plurality of binding sites capable of binding with the protein having certain amino acid sequences so as to form a moiety-protein complex, and mixing the complex with a marker specific for the moiety in an amount sufficient to indicate existence of the complex.

Abstract: The present invention relates to systems, compositions, and methods for the detection and characterization of nucleic acid sequences and variations in nucleic acid sequences. The present invention relates to methods for attaching nucleic acids to solid supports and modifying nucleic acids. For example, in some embodiments, the 5? nuclease activity of a cleavage agent is used to cleave a cleavage structure formed on the solid support, the occurrence of the cleavage event indicating the presence of specific nucleic acid sequences.

Abstract: A method for recombinant antibody subunit dimerization including modifying at least one codon of a nucleic acid sequence to replace an amino acid occurring naturally in the antibody with a charged amino acid at a position in the interface segment of the light polypeptide variable region, the charged amino acid having a first polarity; and modifying at least one codon of the nucleic acid sequence to replace an amino acid occurring naturally in the antibody with a charged amino acid at a position in an interface segment of the heavy polypeptide variable region corresponding to a position in the light polypeptide variable region, the charged amino acid having a second polarity opposite the first polarity. Nucleic acid sequences which code for novel light chain proteins, the latter of which are used in conjunction with the inventive method, are also provided.
