Compositions, devices and methods are described for improving adhesion, attachment, and/or differentiation of cells in a microfluidic device or chip. In one embodiment, one or more ECM proteins are covalently coupled to the surface of a microchannel of a microfluidic device. The microfluidic devices can be stored or used immediately for culture and/or support of living cells such as mammalian cells, and/or for simulating a function of a tissue, e.g., a liver tissue, muscle tissue, etc. Extended adhesion and viability with sustained function over time is observed.

The present invention relates to compositions forming a low viscosity mixture of: a) 20-80 wt. % of at least one diacyl glycerol and/or a tocopherol; b) 20-80 wt. % of at least one phosphatidyl choline (PC); c) 5-20 wt. % of at least one biocompatible, organic mono-alcoholic solvent; d) up to 20 wt. % polar solvent e) at least one peptide active agent; f) optionally at least one antioxidant; wherein the ratio of components a:b is in the range 40:60 to 54:46; wherein the pre-formulation forms, or is capable of forming, at least one liquid crystalline phase structure upon contact with excess aqueous fluid. The invention further relates to methods of treatment comprising administration of such compositions, and to pre-filled administration devices and kits containing the formulations.

According to some embodiments, a method of reducing the spread of infection by a target pathogen in a host comprises binding a carrier to a target areas of the host's cells to reduce a likelihood that the target pathogen binds to the target areas, thereby blocking at least some of the target areas, and providing a gained advantage to the host's immune system to fight a disease caused by the target pathogen, wherein providing the gained advantage comprises decorating the carrier with epitopes to be used as a vaccination at target cell populations.

According to some embodiments, a carrier for reducing a likelihood of a pathogen binding to cell structures of a host comprises a core, surface features extending from an exterior surface of the core, wherein the surface features are configured to bind to target areas of cell structures of the host to at least partially block the pathogen from binding to said target areas as a result of competitive inhibition, and a plurality of binding sites along the exterior surface, wherein the binding sites are configured to attract at least one portion of the pathogen, wherein the binding sites are recognizable by the pathogen and are able to be bound by the pathogen, thereby at least partially immobilizing the pathogen and reducing the likelihood of the pathogen binding to target areas of cell structures of the host.

The present disclosure relates to lipoprotein complexes and lipoprotein populations and their use in the treatment and/or prevention of dyslipidemic diseases, disorders, and/or conditions. The disclosure further relates to recombinant expression of apolipoproteins, purification of apolipoproteins, and production of lipoprotein complexes using thermal cycling-based methods.

Disclosed herein are isolated compositions including at least 2 of mutant peptides selected from the group consisting of SEQ ID NOS: 1-149, or polypeptides comprising the mutant peptides; wherein the composition comprises mutant peptides encoded by 2 or more genes. Also disclosed are methods for personalized treatment of breast cancer involving creating a peptide array of mutant peptides comprising the mutations in protein-encoding regions of the high-frequency cancer genes or the exome in a subject and screening the peptide array with a biological sample from the subject to detect antibodies in the biological sample that bind to the array, to detect antigenic targets for therapy in treating the subject.

Provided herein are methods and compositions for purifying antibodies. Purification is achieved by increasing the binding capacity of protein A chromatography by covalent attachment of a protein A domain (E, D, A, B, C), or domain Z, or a functional variant thereof, to Drosophila melanogaster transcription factor Ultrabithorax (Ubx) materials. The compositions include fusion proteins containing Drosophila melanogaster transcription factor Ultrabithorax (Ubx) or a fragment thereof and an immunoglobulin binding protein. In some embodiments, the immunoglobulin binding protein is a protein A domain, a protein Z domain or a fragment thereof.
