Abstract: Disclosed is a method for producing a recombinant protein of interest, characterised in by the following steps: (a) providing a fusion protein comprising an Npro autoprotease moiety and a protein of interest moiety in inclusion bodies, (b) solubilising the fusion protein in the inclusion bodies by subjecting the inclusion bodies to a solubilisation buffer containing a detergent and wherein the solubilisation buffer contains no chaotropes or chaotropes in a concentration of less than 1.5 M urea (c) refolding the solubilised fusion protein and (d) allowing the fusion protein to be cleaved by the Npro autoprotease moiety under kosmotropic conditions, wherein the recombinant protein of interest is cleaved from the fusion protein, and (e) recovering the protein of interest.

Abstract: A wireless, multitenant video intercom door station is provided, along with methods for operating same. A common door station may be installed near a property entry door. The common door station may be utilized to select a desired tenant, and identify one or more tenant door stations and/or tenant personal electronic devices associated with the desired tenant. Notifications may be transmitted to the tenant door stations and/or devices. A tenant may respond to the notification to initiate a video intercom session. Communications may be routed through a cloud server for recording of communication content and/or activity logging.
