The present invention relates to a method for quantifying a therapeutic antibody in a sample of a human individual comprising a step of adding to a test sample which may contain therapeutic antibodies to be quantified a known amount of two or more labeled forms of said therapeutic antibodies.

The present invention provides a sufficiently effective medicine for treatment and/or prevention of ischemic diseases, without performing isolation of therapeutic cells or removal of deleterious cells from blood cells/hemocytes. The blood cells and/or the hemocytes are subjected to the action of a saccharide. The saccharide is a monosaccharide, a disaccharide, a trisaccharide, a polysaccharides, or a copolymer containing a monosaccharide, a disaccharide, or a trisaccharide as a component. The saccharide is a copolymer of sucrose and epichlorohydrin.

Proteases regulate a wide range of normal cellular functions where dysregulated activity is observed in various diseases. Compositions and methods use protease activity multiplexed bead-based immunoassays to profile protease activity. This platform technology integrates protease activity measurements with total protein quantification techniques. It represents a significant improvement over existing detection techniques by allowing for multiplexed, sensitive active protease measurements in complex biological samples. Exemplary multiplexed detections are realized in a single assay using a minute sample amount (e.g., 5 μl) for active recombinant MMP-1, -2, -3, -7, 9, and 12 and those same MMPs in cell culture supernatant, menstrual fluid effluent, and peritoneal aspirates. This multiplexed platform achieves high level of sensitivities equal to or better than existing leading single-plex detection strategies. It also allows for high throughput screening to identify inhibitors of proteases in complex, donor-derived samples.

Provided herein are IL-15 cytokine prodrugs and methods of making and using thereof.

Provided are peptides, and conjugates comprising targeting peptides and payloads. The peptides comprise a plurality of modules corresponding to at least one of module 1, module 2, or module 3 of the collagen binding domain of a gelatinase, or a gelatin-binding fragment or variant thereof. The gelatinase may be MMP-2. The conjugates may be therapeutic or non-therapeutic. Medical uses of the peptides or therapeutic conjugates, and pharmaceutical compositions comprising these, are also provided, as are nucleic acids encoding the peptides.

[Problem] To provide a composition and a cell sheet which are highly effective for inhibiting fibrosis, or cells having fibrosis-inhibiting activity, which are useful in regenerative medicine. [Solution] A medium containing IC-2 or a related compound is inoculated with mesenchymal stem cells or bone marrow mononuclear cells, and the cells are cultured for a prescribed period of time while the IC-2 or related compound is maintained at a constant concentration, thereby allowing a composition and a cell sheet which are highly effective for inhibiting fibrosis, or cultured cells having fibrosis-inhibiting activity, to be obtained.

Provided herein are IL-15 cytokine prodrugs and methods of making and using thereof.

Provided herein are IL-15 cytokine prodrugs and methods of making and using thereof.

A method of disrupting or reducing a biofilm, the methods comprising contacting the biofilm with a matrix metalloproteinase (MMP). The biofilm may be present on inanimate or biological surfaces. Also, the MMP may be used to prevent the growth of a biofilm on an item, such as a medical device, by applying the MMP to the item. Also, therapeutic compositions comprising the MMP, which may be used to treat an individual having a biofilm-associated disease or disorder.

The disclosure provides constructs comprising a first fusion protein, a second fusion protein, and a linker, wherein the first fusion protein and the second fusion protein each include an affinity reagent and a reactive enzyme, and the linker includes a first and second functional groups specific for irreversibly inhibiting the first and second fusion protein reactive enzymes. The disclosure further provides a method including (a) contacting a first fusion protein including an affinity reagent and a reactive enzyme with a linker including a functional group specific for irreversibly inhibiting the first fusion protein reactive enzyme thereby coupling the first fusion protein and the linker, and (b) contacting a second fusion protein including an affinity reagent and a reactive enzyme with the linker, the linker including a functional group specific for irreversibly inhibiting the second fusion protein reactive enzyme thereby coupling the second fusion protein and the linker.
