Methods and assays for detecting natalizumab in a sample, natalizumab-peptide complexes in a sample, and point-of-care devices for detecting natalizumab in a sample are described herein.

Detection and quantification of natalizumab

Complexes comprising a therapeutic monoclonal antibody and a peptide are provided. In some embodiments, the complexes may comprise a therapeutic monoclonal antibody which is not complexed to an epitope of a target protein and a peptide complexed to the therapeutic monoclonal antibody. In some embodiments, the peptide may have a length of about 5-40 amino acids and may comprise a mimetope recognized by the therapeutic monoclonal antibody, wherein the mimetope comprises a linear sequence of amino acids which is different than a linear sequence of amino acids in the epitope of the target protein.

Methods for detecting antibodies

Disclosed are methods, systems, and devices for implementing nanoparticles to encapsulate biomolecules such as enzymes. In one aspect, a nanoparticle device includes a shell structure including an internal layer structured to enclose a hollow interior region and include one or more holes penetrating through the internal layer, and an external layer formed of a porous material around the internal layer; and an enzyme contained within the interior region of the shell structure, the enzyme having entered the shell structure through the one or more holes and incapable of passing through the external layer, in which the pores are of a size that prevents the enzyme to pass through the pores while permitting substances smaller than the pore size to pass through the pores.

Enzyme-encapsulated nanoparticle platform

Point-of-care diagnostic device

Methods for detection of any antibody utilizing a standardized approach applicable to any antibody which provides highly specific assays specific for individual or multiple antibodies. The methods enable improved pharmacokinetic analysis during development and clinical use of antibody-based therapies as well as determination of diagnostic and/or prognostic factors.

The present technology relates to a nanoparticle platform based on the unique and varied properties of DNA. Circular DNA can be replicated using a strand displacing polymerase to generate long linear concatamers of controllable length that spontaneously fold into a ball conformation due to internal base-pairing. These balls of DNA are discreet particles that can be made in variable sizes on a nanometer size scale in a scalable manner. The particles can be used in a variety of manners, discussed herein, including specific targeting, drug delivery to cancer cells, and diagnostics. Nanoparticles may also serve as multifunctional platforms for the integration of many currently used cancer therapeutic techniques.
