Provided herein are materials and methods that include utilizing atom transfer radical polymerization (ATRP) initiator molecules that maintain a positive charge during biomacro-initiator synthesis.

The present invention is directed to a digestive enzyme composition comprising an enterically coated digestive enzyme product, administrable nutritional medium, and a pharmaceutically acceptable low viscosity oily ingredient. The process for the preparation of the digestive enzyme composition comprises adding an enterically coated digestive enzyme product to a administrable nutritional medium and pharmaceutically acceptable low viscosity oily ingredient. The invention further provides a method for treating a patient suffering from exocrine pancreatic insufficiency related condition comprising administering to the patient a therapeutically effective dose of the digestive enzyme composition by means of a feeding tube.

A cell hydrolysate composition, the composition comprising substantially all protein polypeptides and/or polypeptide fragments derived substantially from all the proteins in a cell from an in vitro cell culture.

A therapeutic agent for the treatment of toxemia, preeclampsia and eclampsia and a method for preparing the therapeutic agent are disclosed. The therapeutic agent is a stable pharmaceutical preparation containing, but not limited to, digestive/pancreatic enzymes. The therapeutic agent may be manufactured by a variety of encapsulation technologies. Delivery of the therapeutic agent may be made orally, through injection, by adherence of a medicated patch or by other methods. Further, a method of using the presence of chymotrypsin in the maternal GI tract as a biomarker, to determine the likelihood of developing preeclampsia, a pregnancy induced hypertension, and eclampsia/toxemia is disclosed.

The present invention discloses monodisperse protein-dendron conjugates that self-assemble to generation-dependent supramolecular protein assemblies of different size and surface charges. The invention further provides a process for synthesis of protein-dendron conjugates containing hydrophobic dendron of different generations.

The invention provides novel compositions of bioactive polypeptides and proteins with improved stability and shelf-life. The compositions are based on liquid vehicles selected from semifluorinated alkanes. These vehicles are remarkably effective in protecting polypeptides and proteins from degradation and/or aggregation. The compositions are useful for topical administration, e.g. into an eye, or by parenteral injection, e.g. via the subcutaneous or intramuscular route.

Embodiments of the invention provide at least one polymer covalently conjugated to an esterase. The at least one polymer includes a plurality of oxime functional groups.

An adsorbent, which can be produced by a method in which a particle size, a pore size, a specific surface area or the like can be easily controlled, and is suitable for isolation of biomolecules. The adsorbent contains aggregates of calcium phosphate-based particles, and has an average pore size of 15 to 36 nanometers and a specific surface area of 40 to 90 m.sup.2/mL when measurement is carried out by mercury porosimetry.

Disclosed are a method for preparing a biomaterial having selectively functionalized tyrosine, a biomaterial having selectively functionalized tyrosine, and a pharmaceutical composition containing same as an active ingredient. The method for preparing a biomaterial to which a compound represented by chemical formula 2 is coupled, of the present invention, allows the compound represented by chemical formula 2 to be selectively coupled, in a high yield in a biomaterial, to tyrosine, which is present on the surface of an aqueous solution such that the coupling thereof to amino acids other than tyrosine does not occur and, when only one tyrosine is present, heterogeneous mixtures are not present and the inherent activity of the biomaterial is maintained, and thus the compound can be effectively used as a pharmaceutical composition containing a biomaterial drug as an active ingredient. In addition, the method can selectively functionalize tyrosine, and thus can be effectively used for tyrosine functionalization in a biomaterial.
