Immunodetection and quantification of vascular endothelial growth factor receptor-3 in human malignant tumor tissues.

Vascular endothelial growth factor receptor-3 (VEGFR-3) and its ligands, vascular endothelial growth factor-C (VEGF-C) and -D (VEGF-D), are the major molecules involved in developmental and pathological lymphangiogenesis. Here we describe for the first time the development of a specific indirect enzyme-linked immunosorbent assay (ELISA) for the quantification of VEGFR-3 in different human cell and tissue lysates. A combination of the goat polyclonal anti-VEGFR-3 antibody and the mouse monoclonal anti-human VEGFR-3 antibody was used.

Quantification of vascular endothelial growth factor-C (VEGF-C) by a novel ELISA.

Lymphangiogenesis plays an important role in several normal and pathological conditions such as wound healing, inflammation or metastasis formation in several malignancies. VEGF-C and VEGF-D are important and specific regulatory factors for lymphatic endothelial proliferation and lymphangiogenesis. In order to develop a highly sensitive and specific detection system for VEGF-C, we produced soluble binding proteins and antibodies for a microtiterplate-based assay.

Renaturation and purification of bone morphogenetic protein-2 produced as inclusion bodies in high-cell-density cultures of recombinant Escherichia coli.

Eschericha coli was genetically engineered to produce recombinant human bone morphogenetic protein-2 (rhBMP-2) in a non-active aggregated form using a temperature-inducible expression system. High concentrations of both biomass (75 g cell dry weight per liter of culture broth) and inactive rhBMP-2 (8.6 gl(-1)) were obtained by applying a high-cell-density cultivation procedure.
