Described herein are fluid treatment devices for use in tangential flow filtration, comprising a housing unit and a composite material, wherein the composite material comprises: a support member comprising a plurality of pores extending through the support member; and a non-self-supporting macroporous cross-linked gel comprising macropores having an average size of 10 nm to 3000 nm, said macroporous gel being located in the pores of the support member. The invention also relates to a method of separating a substance from a fluid, comprising the step of placing the fluid in contact with an inventive device, thereby adsorbing or absorbing the substance to the composite material contained therein.

Provided are methods for linking polypeptides (including peptides and proteins) to other moieties using radical imitated thiol-ene chemistries, for example, modifying a polypeptide by introducing reactive thiol groups and reacting the thiol groups with olefin-containing reagents or alkyne-containing reagents under conditions that support radical thiol-ene or thiol-yne reactions. The reactive thiol groups have greater activity for radical thiol-ene reactions that a cysteine thiol group, including thiol groups that are separated from the peptide backbone by at least two carbon atoms, for example, the thiol group of a homocysteine residue. Also provided are compositions and biomaterials containing the linked polypeptides, for example, peptide and protein conjugates, and thiol-ene based biocompatible hydrogel polymers, and their uses in the medical field.

The invention relates to the field of medicine, specifically to the field of treatment of conditions associated with Staphylococcus infection. The invention relates to a novel endolysin polypeptide specifically targeting a bacterial Staphylococcus cell. The invention further relates to said endolysin polypeptide for medical use, preferably for treating an individual suffering from a condition associated with Staphylococcus infection.

The invention encompasses formulations and methods for the production thereof that permit the delivery of concentrated protein solutions. The inventive methods can yield a lower viscosity liquid protein formulation or a higher concentration of therapeutic or nontherapeutic proteins in the liquid formulation, as compared to traditional protein solutions. The inventive methods can also yield a higher stability of a liquid protein formulation.

The present invention provides a process for producing complexes of high isoelectric point proteins with casein comprising a specific sequence of heating, cooling and holding steps. Also provided are the complexes obtained by such process and their use, in particular their use in methods of therapy.

The present invention provides methods and compositions to reduce growth of microbial colonies, including infections, and includes therapeutic compositions, methods for treatment of infections, and methods for identifying additional such compositions.

The present disclosure is directed to lysin-AMP polypeptide constructs, isolated lysin polypeptides, and pharmaceutical compositions comprising the isolated polypeptides and/or lysin-AMP polypeptide constructs. Methods of using the lysin-AMP polypeptide constructs, isolated lysin polypeptides and pharmaceutical compositions are also herein provided, including methods of treating a bacterial infection of an organ or tissue in which pulmonary surfactant is present or Gram-negative bacterial infections that are associated with a biofilm. In addition, isolated polynucleotides encoding the lysin-AMP polypeptide constructs and isolated lysin polypeptides are disclosed herein.

This document relates to conjugates of TNF inhibitors or derivatives thereof and functionalized (e.g., mono- or bi-functional) polymers (e.g., polyethylene glycol and related polymers) as well as methods and materials for making and using such conjugates.

The present invention relates in general to the field of antimicrobial enzymes. In particular, the present invention relates to a polypeptide comprising the amino acid sequence of a globular Gram-negative endolysin and the amino acid sequence of a cell wall binding domain of i) a modular Gram-negative endolysin or ii) a bacteriophage tail/baseplate protein. The present invention relates also to corresponding nucleic acids, vectors, bacteriophages, host cells, and compositions. The present inventions also relates to the use of said polypeptides, nucleic acids, vectors, bacteriophages, host cells, and compositions in methods for treatment of the human or animal body by surgery or therapy or in diagnostic methods practiced on the human or animal body. The polypeptides, nucleic acids, vectors, bacteriophages, host cells, and compositions according to the invention may also be used as an antimicrobial in, e.g., food or feed, in cosmetics, or as disinfecting agent.

The present invention relates to animal feed compositions comprising at least one probiotic and polypeptides having muramidase activity.
