Abstract: Nucleic acid molecules comprising a nucleic acid sequence that encodes an amino acid sequence wherein the amino acid sequence consists of the variable region or of the hypervariable region of a monoclonal antibody that specifically binds to an extracellular domain of a VEGF receptor and neutralizes activation of the receptor.

Abstract: The present invention is directed to a method of amplifying and detecting single or double stranded target nucleic acid molecules. Amplification of the target nucleic acid molecule is accomplished by using at least two chemically modified oligonucleotide probes per target nucleic acid molecule to form a joined oligonucleotide product. Each oligonucleotide probe is comprised of a long and short sequence. The long sequence of each probe hybridizes to adjacent regions of the target nucleic acid molecule. The short sequences of each probe hybridize to each other. Chemical functionality groups attached to the short sequences of each oligonucleotide probe covalently combine linking the probes to form a joined oligonucleotide product. The joined oligonucleotide product is formed without the use of enzymes.The reactivity of the chemical functionality groups on each probe is target dependent.
