Abstract

Abstract A detectable molecule of the formula A3-(-X-R1-E-Detb)m where A3 is A2 or a polymer, where A3 has at least one modifiable reactive group selected from the group consisting of amino, hydroxy, cis OH, halides, aryl, imidazoyl, carbonyl, carboxy, thiol or a residue comprising an activated carbon; -X- is selected from the group consisting of <IMAGE> <IMAGE> <IMAGE> <IMAGE> +TR <IMAGE> a C1-C10 branched or unbranched alkyl or aralkyl, which may be substituted by -OH; -Y- is a direct bond to -E-, or -Y- is -E-R2- where R2 is a C1-C10 branched or unbranched alkyl; Za is chlorine, bromine or iodine; E is O, NH or an acyclic divalent sulfur atom; Detb is a chemical moiety capable of being detected, preferably comprising biotin or a metal chelator of the formula: <IMAGE> or the 4-hydroxy or acyloxy derivative thereof, where R3 is C1-C4 alkyl or CH2COOM, M is the same or different and selected from the group consisting of hydrogen, a metal or non-metal cation or is C1-C10 alkyl, aryl or aralkyl; and m is an integer from 1 to the total number of modified reactive groups on A3. The detectable molecules are useful in vitro or in vivo assays or therapy.
