Methods of intracellular conversion of single-chain proteins into their di-chain form

The present specification discloses expression constructs comprising single-chain proteins comprising a di-chain loop region comprising an exogenous protease cleavage site and a protease that can cleave the exogenous protease cleavage site located within the di-chain loop, cell compositions comprising such expression construct, and intracellular methods of converting the single-chain protein into its di-chain form.

Fused NHase with improved specific activity and stability

The present invention provides a fused NHase with improved specific activity and stability, which relates to the field of genetic engineering. This invention provides a method of overexpressing a fused NHase in E. coli and producing a mutant NHase with improved stability and product tolerance. The invention provides a simple, efficient and safe method of making mutant NHase, and can produce a large amount of soluble NHases in a short period. The present invention makes a contribution to large-scale industrial production and further theoretical study of NHases.

Variants of C-type natriuretic peptide

The present disclosure provides variants of C-type natriuretic peptide (CNP), pharmaceutical compositions comprising CNP variants, and methods of making CNP variants. The CNP variants are useful as therapeutic agents for the treatment of diseases responsive to CNP, including but not limited to bone-related disorders, such as skeletal dysplasias (e.g., achondroplasia), and vascular smooth muscle disorders (e.g., restenosis and arteriosclerosis).

Vaccine and therapeutic delivery system

The present invention relates to a new vaccine delivery system. In particular, the present invention includes compositions and methods of integrally transformed non-pathogenic, commensal bacteria that can express a nucleic acid molecule of a foreign polypeptide, wherein the nucleic acid molecule that encodes the foreign polypeptide is stably integrated into genomic DNA of the bacteria. The foreign polypeptide includes a vaccine antigen that elicits an immunogenic response, an inhibitor of a pathogen, or an immune booster or modulator.

Stabilized liquid anti-RSV antibody formulations

The present invention provides liquid formulations of SYNAGIS or an antigen-binding fragment thereof that immunospecifically bind to a respiratory syncytial virus (RSV) antigen, which formulation exhibit stability, low to undetectable levels of aggregation, and very little to no loss of the biological activities of SYNAGIS or an antigen-binding fragment thereof, even during long periods of storage. In particular, the present invention provides liquid formulations of SYNAGIS or an antigen-binding fragment thereof which immunospecifically binds to a RSV antigen, which formulation are substantially free of surfactant, inorganic salts, and/or other common excipients. Furthermore, the invention provides method of preventing, treating or ameliorating symptoms associated with RSV infection utilizing liquid formulations of the present invention.
