The invention relates to improvements in drug delivery and to the use of Cell Penetrating Agents (CPA's) or Cell Penetrating Peptides (CPP's) which have been stabilized by, for example: i) stapling two amino acids to form Stapled CPP's (StaP's) or ii) stitching three or more amino acids to form stitched CPP's (StiP's). More particularly there is provided a drug carrying cell penetrating molecule (DCCPM) comprising: a biologically active compound (BAC), and a cell penetrating agent (CPA), which BAC and CPA are linked directly or via a bi-functional linker (BFL). The CPA is a stabilized peptide (CPP) which has a conformation imposed upon it by stapling to form a stapled peptide (StaP) or stitching to form a stitched peptide (StiP). The StiP or StaP comprise a cross link or bridge between at least two amino acids of the peptide and the cross link or bridge provides a cyclisation between at least two amino acids which are not formed by an olefin metathesis. Cyclisation may be achieved by one or more of: condensation of an aldehyde or ketone with a hydrazine or protected hydrazine; a thiol-ene Michael addition; a di-sulfide formation; a Huisgen 1,3 di-polar cycloaddition; a reaction between an amine and carboxylic acid; a singlet or triplet based carbine reaction; or a Suzuki or Sonogashira coupling.

The present disclosure relates to relates methods and associated compositions that provide fast, efficient site-selective conjugation of a protein, such as the pore-forming protein α-hemolysin, to a biomolecule, such as a DNA polymerase, and the use of such site-selective protein-biomolecule conjugates in nanopore devices and methods.

The present invention relates to a peptide hormone with one or more O-glycans attached at specific amino acid residues as well as to formulations comprising the same.

Methods and reagents for the installation of click chemistry handles on target proteins are provided, as well as modified proteins comprising click chemistry handles. Further, chimeric proteins, for example, bi-specific antibodies, that comprise two proteins conjugated via click chemistry, as well as methods for their generation and use are disclosed herein.

The present invention comprises conjugates comprising a monoclonal antibody conjugated to a cyclic PYY peptide. The invention also relates to pharmaceutical compositions and methods for use thereof. The novel conjugates are useful for preventing, treating or ameliorating diseases and disorders disclosed herein.

The present invention relates to a monoclonal antibody platform designed to be coupled to therapeutic peptides to increase the half-life of the therapeutic peptide in a subject. The invention also relates to pharmaceutical compositions and methods for use thereof.

The present disclosure relates to relates methods and associated compositions that provide fast, efficient site-selective conjugation of a protein, such as the pore-forming protein α-hemolysin, to a biomolecule, such as a DNA polymerase, and the use of such site-selective protein-biomolecule conjugates in nanopore devices and methods.

The present invention comprises compounds of Formula I. ##STR00001## wherein: Z.sub.4, Z.sub.7, Z.sub.9, Z.sub.11, Z.sub.22, Z.sub.23, Z.sub.26, Z.sub.30, Z.sub.34, Z.sub.35, p, m, n, q, and BRIDGE are defined in the specification. The invention also relates to pharmaceutical compositions and methods for use thereof. The novel compounds are useful for preventing, treating or ameliorating diseases and disorders, such as obesity, type 2 diabetes, the metabolic syndrome, insulin resistance, and dyslipidemia, among others.

Provided are methods of producing antigenic proteins and antigenic protein complexes and compositions and vaccines produced from such methods. Also provided are methods of immunizing a subject using such compositions and vaccines. The antigenic proteins and protein complexes of this disclosure are useful as vaccine immunogens that can direct the immune system of a subject immunized with such vaccine immunogens to generate antibodies against a specific region, or epitope, of a protein that is known to be productive or neutralizing in the case of an infection. Also provided are methods of screening for B cells expressing antibodies that bind specifically to a particular, desired epitope (target region). Compositions and kits comprising one or more antigenic protein, protein complexes, binding partners, and polynucleotides encoding any thereof, are also described.

Methods of and compositions for producing and using plant-based materials are provided. The methods include using biopolymers or their synthetic equivalents combined with a stable source of reactive oxygen species that when applied to or combined with a separate source of oxido-reducing enzyme or catalyst will cause the formation of an activated biopolymer with increased protein binding affinity and microbial control activities.
