transfection efficiency of about 80 % was achieved. The NTP/U ratio has been shown to detect the age of the cell line and to monitor the transfection process. It revealed a high energy level and an exponential growth as best prerequisite for obtaining a high productivity in transiently transfected HEK293 cells in suspension culture.

negative regulators of cell division. Upon being bound by SV40 large T antigen, p53 and Rb are inactivated and the cells have an unlimited life span. There are a number of good reviews on immortalization (.–.) that deal in greater detail with biology involved in the process which is beyond the scope of this review.

ses on cell lines are now available internationally for ATCC clients via CODATA and TYMNET or Telenet networks. By using the databases one can quickly retrieve information about specific lines or create lists of lines with specific characteristics.

Coupling Mobility and Security,e (MN) so that they arrive at the new point of attachment. This is the goal of mobile IP [1]: providing a host with the ability to stay connected to the Internet and its services regardless of its location. In this chapter, we focus on mobile IPv6 (MIPv6) [2] and its security features.

Voice over Internet Protocol, service investigated in this book – voice over Internet protocol (VoIP) – are introduced in section 3.1. Section 3.2 shows the Media session parameters involved in a VoIP session. Section 3.3 presents the signalling protocols, namely H.323 and the session initiation protocol (SIP).
