    摘要: The present invention deals with the proteolytic enzyme thermolysin which tends to be unstable in aqueous solution. The invention provides methods and compositions to enhance the stability of dissolved thermolysin in aqueous solution. Thermolysin, crude thermolysin or a lyophilizate containing thermolysin and one or more salts, is contacted with an aqueous buffer with a low salt concentration and a first solution is formed. Subsequently, a further salt in solid form is added and dissociated, thereby forming a second solution comprising thermolysin in a stabilized form.

    摘要: Data traffic is routed from a customer edge (CE) router to an Ethernet services router via a generic routing encapsulation (GRE) tunnel. Upon routing the data traffic from the CE router to the Ethernet services router, the data traffic is routed from the Ethernet services router to an aggregation switch. Upon routing the data traffic from the Ethernet services router to the aggregation switch, the data traffic is routed from the aggregation switch to a service switch through a security module, the security module configured to filter the data traffic. The filtered data traffic is routed from the service switch to the Ethernet services router. Upon routing the filtered data traffic from the service switch to the Ethernet services router, the filtered data traffic is routed from the Ethernet services router to a provider edge (PE) router.
