Abstract: Provided are pan-cell surface receptor-specific therapeutics, methods for preparing them and methods of treatment using them. Among the pan-cell surface receptor-specific therapeutics are pan-HER-specific therapeutics that interact with at least two different HER receptor ligands and/or dimerize with or interact with two or more HER cell surface receptors. By virtue of these properties, the therapeutics modulate the activity of at least two cell surface receptors and are useful for therapeutic purposes.

Abstract: Isoforms of ligands, including isoforms of hepatocyte growth factor (HGF) containing an intron-encoded portion, and pharmaceutical compositions containing HGF isoforms are provided. The HGF ligand isoforms and compositions containing them can be used in methods of treatment of diseases, such as cancer and other angiogenic diseases.

Abstract: The invention provides assay methods for the detection and quantitation of gastrin hormones, including total and free gastrin hormone in a sample. ELISA-type heterogeneous phase assays suitable for use with biological fluid samples such as blood, plasma or other bodily fluids of a mammal, particularly a human subject are provided. The method provides a precise assay for the amounts of free and total G17 and G34 in biological fluid samples, as well as the amounts of free and total Gly-extended G17, and Gly-extended G34. Also provided are methods of determining suitable treatment for patient suffering from a gastrin hormone-mediated disease or condition employing gastrin hormone immunoassays.
