  • Patent number: 7338778
    Abstract: The present invention relates to methods for detection and evaluation of metabolic activity of eukaryotic and/or prokaryotic cells based upon their ability to consume dissolved oxygen. The methods utilize a luminescence detection system which makes use of the sensitivity of the luminescent emission of certain compounds to the presence of oxygen, which quenches (diminishes) the compound's luminescent emission in a concentration dependent manner. Respiring eukaryotic and/or prokaryotic cells will affect the oxygen concentration of a liquid medium in which they are immersed. Thus, this invention provides a convenient system to gather information on the presence, identification, quantification and cytotoxic activity of eukaryotic and/or prokaryotic cells by determining their effect on the oxygen concentration of the media in which they are present.

  • Patent number: 5681931
    Abstract: Human restrictin proteins and nucleic acid sequences encoding them are provided. Antibodies which recognize human restrictin in human brain are disclosed. In the human brain, restrictin occurs as two major polypeptides of 180 and 160 kD located in fiber tracts. These polypeptides are similar to those seen in rat brain. Surprisingly, restrictin has also been found in the peripheral nerves of rats and humans. The antibodies also detect a 170 kD polypeptide in MATRIGEL, an extracellular matrix product of rat EHS sarcoma cells widely used as a tissue culture substrate. Monoclonal antibodies to human restrictin and assays using the human restrictin protein, antibodies and DNA sequences are also provided.

  • Patent number: 5667978
    Abstract: The present invention provides an anti-N-CAM monoclonal antibody which enhances, rather than inhibits, neurite outgrowth both in vitro and in vivo. The antibody has positive regulatory effects on nerve cells of both the central and peripheral nervous systems, and is useful for enhancing neurite outgrowth in in vitro studies and for improving nerve regeneration and repair in vivo.
