Abstract: A fluorophore that forms a complex with Pb ions is disclosed. The fluorophore/lead complex fluoresces with an intensity greater than complexes formed by the fluorophore with other metals. The fluorophore may be used as a sensor/detector for lead ions in various samples. Methods for detecting and calculating the concentration of lead ions in samples are also disclosed.

Abstract: The present invention provides user-directed construction of novel specific homo- and hetero-dimeric, and multimeric assemblages of proteins. The present invention is comprised of gene sequences that transcribe peptide sequences that form links between proteins, where the peptide sequences produce a hook or loop which supports specific self-assembly of homo-dimers, hetero-dimers and multimers of the proteins to which they are attached. The hook or loop may have a short aliphatic repeat sequence and a metal binding loop. The present invention also provides a method of constructing a hook motif of metal binding loop sequences that may be attached to at least one aliphatic repeat sequence to produce the assemblages of proteins. Also provided are protein structures produced by the methods of the present invention.

Abstract: An ophthalmic instillation composition which contains melatonin and at least one other hormone, typically an estrogen but also possibly testosterone or another aromatasable androgen. The instillation is designed to reduce or eliminate cataracts in men or women to which such an ophthalmic instillation composition is administered.
