Abstract: This application relates to methods for purification of proteins such as antibodies using a hydrophilic polymer (e.g., PEG), a fatty acid (e.g., caprylic acid), and/or another agent (e.g., calcium chloride).

Abstract: A method which facilitates the secure addressing and authentication for the establishment of connections as well as the secure storage of data and the avoidance of the issue of data to third parties. Furthermore it enables secure payment via data links. Thus it relates in particular a method for addressing, authentication and data storage for “Private Cloud” networks and secure payment via data links.

Abstract: This application relates to methods for purification of proteins such as antibodies using a hydrophilic polymer (e.g., PEG), a fatty acid (e.g., caprylic acid), and/or another agent (e.g., calcium chloride).

Abstract: A system and method is provided for addressing, authentication and secure data storage in computer systems with a first, second and/or third computer system with at least one network interface and at least one telephony interface. The connection information for the network interface of at least one first computer system is transmitted via the telephony interface to at least the second and/or third computer system. A call number associated with each computer system is checked and appropriate network interfaces are activated if the result(s) of the check is/are positive. Connections with the connection information of the first computer system are only allowed by the network interface of the second computer system, and vice versa. Network interfaces only allow connection attempts with respective connection information, once connection is established, or not established for a predetermined time, the network interfaces are not recognizable or reachable by other computer systems.
