摘要:
The present invention concerns methods and compositions for subunit-based vaccines for inducing immunity against poxvirus infections, such as smallpox. Preferred embodiments concern immunoconjugates comprising one or more subunit antigenic peptides attached to an antibody or fragment thereof that targets antigen-producing cells (APCs). More preferably, the antibody binds to HLA-DR and the antigenic peptide is from an immunomodulating factor, such as the viral IL-18 binding protein (vIL18BP). However, mixtures of antigenic peptides from different viral proteins may also be used. The vaccine is capable of inducing immunity against poxvirus without risk of disseminated infection in immunocompromised hosts or transmission to susceptible contacts.

The present invention provides a method for preparing a site-specific physiologically active polypeptide conjugate in a high yield by treating a physiologically active polypeptide with a non-peptidyl polymer in the presence of an alcohol at a specific pH, which can be desirably employed in the development of long acting formulations of various peptide drugs having high in-vivo activity and markedly prolonged in-blood half-life.

摘要:
The invention relates to a cyclic peptide comprising the following sequence: -S1-X1-S2-X2- wherein S1 is a first target peptide sequence of a protease enzyme E1, S2 is a second target peptide sequence of a protease enzyme E2, S1 and S2 can be the same or different, the first peptide sequence S1 and the second peptide sequence S2 comprising between 4 and 14 amino acids, E1 and E2 corresponding to the same protease enzyme or to two separate protease enzymes, X1 is a probe carrying a fluorescent donor group, and X2 is a probe carrying a fluorescent or non-fluorescent acceptor group. Said peptides can be used in determining the activity of protease enzymes.
摘要:
A semi-recombinant method for the production of GLP-1 analogues and derivatives with non-proteogenic amino acids in the N-terminal part combining the use of recombinant expression techniques and chemical peptide synthesis.
摘要:
Protein particles are prepared by causing or allowing protein molecules dispersed in a liquid medium at a concentration of 8mg.mL-1 or greater to react in the presence of a zero-length crosslinker, so as to produce protein particles comprising protein molecules that are covalently bonded together. The protein particles may be produced with sizes in the sub-micron range with closely defined sizes and size distributions. The particles have applications in many fields, but are useful inter alia for the delivery of therapeutic agents and other agents, eg imaging contrast agents, to the body.
摘要:
An antibody and immunogen for generating an antibody to nitrofuran and/or nitrofuran metabolite such as tissue or protein bound nitrofuran metabolites. Nitrofurans and and/or nitrofuran metabolites in a biological sample can be detected by contacting the sample with the antibodies to form a complex that can be detected. The antibodies may also be incorporated into test kits for the detection of nitrofuran and/or nitrofuran metabolites.
摘要:
The present invention provides processes for the production of preformed albumin conjugates. In particular, the invention provides processes for the in-vitro conjugation of a therapeutic compound to recombinant albumin, wherein a therapeutic compound comprising a reactive group is contacted to recombinant albumin in solution to form a conjugate. The processes provide for conjugation to albumin species of increasing homogeneity . The resulting conjugate is purified by chromatography, in particular hydrophobic interaction chromatography comprising phenyl sepharose and butyl sepharose chromatography.
