  • Patent number: 8148154
    Abstract: This invention provides a method for identifying cells expressing a target single chain antibody (scFv) directed against a target antigen from a collection of cells that includes cells that do not express the target scFv, comprising the step of combining the collection of cells with an anti-idiotype directed to an antibody specific for the target antigen and detecting interaction, if any, of the anti-idiotype with the cells, wherein the occurrence of an interaction identifies the cell as one which expresses the target scFv. This invention also provides a method for making a single chain antibody (scFv) directed against an antigen, wherein the selection of clones is made based upon interaction of those clones with an appropriate anti-idiotype, and heretofore inaccessible scFv so made. This invention provides the above methods or any combination thereof. Finally, this invention provides various uses of these methods.

  • Patent number: 8101916
    Abstract: This patent presents a method for measuring the concentration of biodiesel in a homogeneous biodiesel-diesel oil mixture using mid infrared radiation for use as fabrication monitor, quality control, law enforcement and multi-fueled vehicles. The method is characterized by the use of mid infrared absorption measurement in the range from 1870 to 1600 cm?1 (5347.6 to 6250.0 nm) which corresponds to the carbonyl group absorption peak (C?O) that is only present in biodiesel. Both intensity and area of the carbonyl absorption peak present power law dependence with the biodiesel percentile in the biodiesel-diesel oil mixture.
