Patent CA-2500441-A1 (CA)
Inventor: WU XAIOJING
IPC: G06K9/32
Filed: 2005-03-11
Abstract: A scannable form, and a method and system of use which incorporates digitally encoded symbols which have identifiable centers that act as control points to permit a digital image to be aligned with a template containing the same control points. The digital encoding permits identification of the type of form and the spatial arrangement of the symbols permits alignment of the form with the template. Preferably, the digital symbols are geometrically symmetrical and the identifiable centers are centroids. Recognition of any three centroids is sufficient to allow the system to calculate transformation parameters to realign the image. Due to the geometrical symmetry, error correction is possible if any of the symbols are incorrectly identified.

Patent CA-2530454-A1 (CA)
Inventor: ROPP PHILIP ALFRED
IPC: B01D15/38
Filed: 2004-06-15
Abstract: During the production of recombinant proteins from gram negative bacteria, lipopolysaccharides (LPS, endotoxin) are released along with the protein of interest. In many instances, LPS will copurify with the target protein due to specific or non~specific protein-ILPS interactions. We have investigated the ability of alkanediols to effect the separation of LPS from protein-LPS  complexes while the complexes are immobilized on anion or cation exchange chromatographic media. Alkanediols provide a safer alternative to the use of other organics such as alcohols or acetonitrile due to their lower toxicity and decreased flammability. In addition, they are less costly than many of the detergents that have been used for such purposes. LPS removal efficiency increased with increasing alkane chain length. 1,2-alkanediols were more effective than terminal alkanediols in the separation of LPS from protein~LPS  complexes.
