Summary for Patent: 8,871,813
Title:Aqueous liquid preparation containing 2-amino-3-(4-bromobenzoyl)phenylacetic acid
Abstract: An aqueous liquid preparation of the present invention containing 2-amino-3-(4-bromobenzoyl)phenylacetic acid or its pharmacologically acceptable salt or a hydrate thereof, an alkyl aryl polyether alcohol type polymer such as tyloxapol, or a polyethylene glycol fatty acid ester such as polyethylene glycol monostearate is stable. Since even in the case where a preservative is incorporated into said aqueous liquid preparation, the preservative exhibits a sufficient preservative effect for a long time, said aqueous liquid preparation in the form of an eye drop is useful for the treatment of blepharitis, conjunctivitis, scleritis, and postoperative inflammation. Also, the aqueous liquid preparation of the present invention in the form of a nasal drop is useful for the treatment of allergic rhinitis and inflammatory rhinitis (e.g. chronic rhinitis, hypertrophic rhinitis, nasal polyp, etc.).

Title: Enhanced Anti-Myelin Antibody Detection using Immunoprecipitation and LC-MS/MS

Patent ID: US 8,871,813 B2 Issued Date: October 25, 2014 Assignee: Harvard University

I. Abstract

The disclosed invention is an improved method for detecting Myelin Oligodendrocyte Glycoprotein (MOG) antibodies, a significant biomarker in the diagnosis of demyelinating diseases such as Multiple Sclerosis (MS). The system involves a two-step approach combining immunoprecipitation (IP) and Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) for enhanced sensitivity and specificity.

II. Background of the Invention

Currently available methods for detecting MOG antibodies rely on ELISA assays, which often yield incorrect results due to false positives and lack of specificity. These limitations hinder the accurate diagnosis of demyelinating diseases and prompt further research to develop a more reliable detection method.

III. Scope of Claims

The patent covers an improved method for detecting MOG antibodies using immunoprecipitation and LC-MS/MS. Key claims include:

  1. A method for detecting MOG antibodies comprising IP using a specific MOG peptide conjugated to resin.
  2. A system for detecting MOG antibodies, which consists of IP apparatus, a LC-MS/MS system, and reagents for peptide conjugation to resin.
  3. The method's applicability in research, clinical, and veterinary settings.

IV. Key Features of the Invention

The invention has several significant advantages:

  1. Increased Sensitivity and Specificity: The IP and LC-MS/MS combination provides high sensitivity and specificity, enabling accurate detection of MOG antibodies.
  2. Robustness: The method is resistant to contamination, false positives, and interferences often encountered in standard ELISA assays.
  3. Flexibility: This system can be adapted for the analysis of various protein antigens, serving as a versatile diagnostic tool.

V. Applications and Potential Impact

The patent's improved detection method may contribute to the development of more accurate and efficient diagnostic tools for demyelinating diseases. It has far-reaching potential in basic research, clinical trials, and personalized medicine, enabling healthcare professionals to more effectively diagnose and manage MS and related conditions.

VI. Considerations and Future Directions

Further refinements to the system, such as optimizing the IP and LC-MS/MS conditions, may be necessary to address specific patient needs and accommodate evolving diagnostic requirements.
