  • Publication number: 20230247412
    Abstract: The present invention discloses a method and system for sending data to and receiving data from a cellular network at a network device. Network device may establish a first cellular connection by using a first wireless communication module (WCM) and a first local Subscriber Identification Module (SIM). After a first data connection is established with the SIM bank via the first cellular connection, a first SIM profile is downloaded from the SIM bank. A second cellular connection is established by using a second WCM and the first SIM profile. After a second data connection is established with the SIM bank via the second cellular connection, disconnecting the first cellular connection. Finally, establishing a third cellular connection by using a third WCM and the first local SIM, and establishing a third data connection with the SIM bank.

  • Patent number: 5908754
    Abstract: The present invention is directed to an in vitro method of determining the in vivo EPO activity of a sample containing EPO. More particularly, the present method comprises treating a sample containing EPO under conditions which remove desialylated EPO, and measuring the in vitro EPO activity of the resulting treated sample. In a preferred embodiment, desialylated EPO is removed from the sample by incubating the sample with cells of the human hepatoma cell line HepG2, and in vitro EPO activity is determined by incubating the treated sample with cells of an EPO-responsive cell line and measuring the proliferation or viability of the EPO-responsive cells. The present invention is useful, for example, in quantitating the biologically active EPO in a variety of sample types.
