  • Patent number: 11369629
    Abstract: A heparin structure with increased anticoagulant activity and method of making the same are disclosed. A heparin sample is provided and treated with a heparan sulfate sulfotransferase in an enzymatic reaction to add sulfuryl groups from a sulfuryl group source to the heparin sample, resulting in a heparin structure having above about 8% more 3-O-sulfo groups relative to wild-type bovine intestinal heparin. The added sulfuryl groups modify the heparin structure and increase the sample's binding to antithrombin III and its anticoagulant activity to be more similar and a viable alternative to porcine intestinal heparin. The modified heparin exhibits an anti-FXa activity and an anti-FIIa activity greater than about 180 U/mg, and a ratio of the anti-FXa activity to the anti-FIIa activity of about 0.9 to about 1.1, consistent with U.S. Pharmacopeia (USP) heparin activity specifications.

  • Patent number: 11196728
    Abstract: Methods and apparatuses are described for caching login sessions to access a software testing environment. A server identifies a test case for execution against an application in the software testing environment, the test case comprising one or more test steps. The server retrieves test data based upon the identified test case and generates a session key using the test data. The server requests an active session from a login session cache using the session key. When an active session exists in the login session cache, the server receives, from the login session cache, session data corresponding to the active session, establishes a connection to the application in the software testing environment using the session data and without first authenticating to the software testing environment, and executes one or more test steps of the test case against the application in the software testing environment using the test data.
