摘要:
The present invention provides compositions useful in preparing and/or serving as antitoxins against Bacillus anthracis, the causative agent of anthrax. The present invention also provides polypeptides and polynucleotides relating to the capillary morphogenisis gene 2 (CMG-2), vectors containing the polynucleotides and polypeptides, and host cells containing related polynucleotide molecules, all used in association with the treatment of, or the research and development of treatments for anthrax. The present invention also relates to methods for identifying molecules that bind CMG-2 and molecules that reduce the toxicity of anthrax toxin. Finally, the present invention provides methods for treating human and non-human animals suffering from anthrax.

摘要:
Methods and apparatus for analyzing surface properties of particles are provided. A method for analyzing the surface properties of the particle includes a associating a first particle with a first capture zone having a specific binding affinity for a first chemical species, applying an optical force to the first particle, sensing a response of the first particle to the optical force, and using the sensed response to determine the presence, absence or quantity of the first chemical species on the first particle surface. This process may be repeated in parallel to test multiple particles. In addition to directly testing the surface properties of the particles, the method can be used in direct, indirect and competitive assays to determine the presence, absence or quantity of free or immobilized analytes. A fluidic cartridge with capture zones having avidities that are tuned for the use of optical forces is provided. A software routine for performing the method is also provided.
摘要:
A method an apparatus for manipulating particles (micro, nano, and pico) having one or more characteristics with an optical trap formed by modulating a laser beam with a Diffractive Optical Element (DOE). At least one characteristic of the material is selected; and a laser beam having a selected wavelength corresponding to the at least one selected characteristic of the material is generated. Values of the DOE are calculated corresponding to the at least one selected characteristic of the material. The beam and the DOE are modulated to produce a holographic optical trap having properties corresponding to the at least one selected characteristic; the trap is focused to a beam focus or selected spot size; and the beam focus is located near a particle location for trapping the particle therein.
摘要:
The present invention employs a beam steering apparatus to isolate valuable cells from other cells, tissues, and contaminants. In one embodiment, the system balances optical trapping against biasing flow to parallelize cell sorting under the flexible control of computer program-directed traps which differentially manipulate cells based on their composition or labels to direct separation.
