摘要: There is provided a single-chain fusion protein comprising: (i) a thermostable kinase and (ii) a single-domain antibody or single-domain antibody fragment. There is also provided a method of preparing a single-domain antibody or single-domain antibody fragment, the method comprising: (i) expressing the single-domain antibody or antibody fragment as a single-chain fusion protein with a thermostable kinase, in a host cell such as E. coli; and (ii) purifying the fusion protein from the cytoplasm of the host cell.

摘要: A non-toxic polypeptide, for delivery of a therapeutic agent to a neuronal cell, comprises a binding domain that binds to the neuronal cell, and a translocation domain that translocates the therapeutic agent into the neuronal cell, wherein the translocation domain is not a HN domain of a clostridial toxin and is not a fragment or derivative of a HN domain of a clostridial toxin.

摘要: A composition for delivery of superoxide dismutase to neuronal cells comprise a superoxide dismutase linked by a linker to a neuronal cell targeting component, which component comprises a first domain that binds to a neuronal cell and a second domain that translocates the superoxide dimutase into the neuronal cell. After translocation, the linker is cleaved to release superoxide dimutase from the neuronal cell targeting domain. Also described is use of the composition for treatment of oxidative damage to neuronal cells and further targeting of the composition using human mitochondrial leader sequences. A hybrid polypeptide is described that contains a bacterial superoxide dismutase plus a sequence that targets a human mitochondira.

摘要: A transmissible spongiform encephalopathy (TSE) agent is inactivated by exposing the TSE agent to a thermostable proteolytic enzyme at elevated temperature and at acid or alkaline pH. Following this step, or separately, presence of TSE infectivity is detected by detection of dimers of prion protein.
