PROBLEM TO BE SOLVED: To provide an affinity support body capable of capturing even any molecule other than an antibody by cooperative connection in which its dissociation is hardly caused and a capturing method using the affinity support body.SOLUTION: A method of capturing a substance includes a step of bringing an object to be captured into contact with an affinity support body containing a support body, a spacer connected to the support body and an affinity substance connected to the spacer to connect the affinity substance to the substance to be captured, in which a plurality of affinity sites exist in one object to be captured, and the affinity substance is simultaneously connected to at least two sites of the affinity sites.

PROBLEM TO BE SOLVED: To provide hybrid immunoglobulins containing moving parts as well as related compositions and methods of use and methods of production, and in addition, analogous genetic devices as well as related compositions and methods of use and methods of production.SOLUTION: Provided is a compound comprising: a first stretch of consecutive amino acids, each of which is joined to the preceding amino acid by a peptide bond and the sequence of which comprises a binding site for a target; and a second stretch of consecutive amino acids, each of which is joined to the preceding amino acid by a peptide bond and the sequence of which is identical to the sequence of the first stretch of consecutive amino acids and which comprises an identical binding site for the target; wherein each of the first stretch of amino acids and the second stretch of amino acids has at a predefined end thereof a cysteine residue or a selenocysteine residue. Such cysteine residues or such selenocysteine residues are joined by a bond having the structure: -C-X-X-C- wherein each X is the same or different and represents a sulfur (S) or a selenium (Se) and each C represents a beta-carbon of one of such cysteine or selenocysteine residues.
