摘要:
A process is disclosed for the production of polyphenol oligomers having n polyphenol monomeric units, n being an integer from 2-18. The process includes coupling of a protected polyphenol, having protected phenolic hydroxyl groups, with a C-4 functionalized polyphenol monomer. The protected polyphenol may be a protected polyphenol monomer or a protected polyphenol oligomer having 2-17 monomeric units. Advantageously, polyphenol monomeric units forming the polyphenol oligomers may be the same or different flavanoid compounds.

摘要:
The generation and validation of a novel monoclonal GREB1 antibody (GREB1ab). Methods for the prognosis, diagnosis, assessment of disease progression, severity and outcome utilize GREB1 molecules as biomarkers. The GREB1 antibody is also a useful tool for investigations focused on the expression, distribution and function of GREB1 in normal and cancer tissues.

摘要:
The present invention relates to blocking peptides which are capable of binding to ligands for the erbB-2 receptor or the epidermal growth factor receptor (EGFR). The blocking peptides of the invention are used to detect the presence of such ligand molecules. In addition, the blocking peptides are useful in inhibiting or preventing the growth of adenocarcinoma cells which express the erbB-2 receptor or the EGFR.
