  • Processing diff-queries on property graphs
    Patent number: 9405855
    Abstract: A system, computer-implemented method, and a computer-readable medium for determining why a query returns a null set in a database management system. When the database management system receives a query graph, database management system compares the query graph to the data graph. Based on the comparison, database management system identifies a discovered component of the query graph and a missing component of the query graph, wherein the missing query component indicates a reason for the null set.
    Type: Grant

  • Methods For Detecting Half-Antibodies Using Chip Based Gel Electophoresis
    Publication number: 20070275481
    Abstract: The invention provides a method of using chip-based gel electrophoresis to determine the presence of polypeptides with selected disulfide linkage patterns, for example, completely formed tetrameric antibodies as compared to incompletely formed heterodimeric half-antibodies. The invention further features a kit, comprising a chip, and instructions for conducting the foregoing method. The methods and kits of the invention are amendable to high throughput applications for the monitoring of production and quality control of recombinant therapeutic antibodies.
