METHOD OF DETECTING TARGET SUBSTANCE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18652258 titled 'METHOD OF DETECTING TARGET SUBSTANCE

Simplified Explanation

The patent application describes a method for detecting a target substance in a sample by using specific binding substances labeled with nucleic acid fragments and detecting the formation of double-stranded nucleic acid.

  • Introducing sample, specific binding substances, and labeled nucleic acid fragments into wells
  • Forming a complex if the target substance is present in the sample
  • Hybridizing the labeled nucleic acid fragments to form double-stranded nucleic acid
  • Detecting the presence of the target substance based on the formation of double-stranded nucleic acid

Key Features and Innovation

  • Utilizes specific binding substances labeled with nucleic acid fragments for target substance detection
  • Formation of double-stranded nucleic acid as an indicator of target substance presence

Potential Applications

  • Medical diagnostics
  • Environmental testing
  • Food safety analysis

Problems Solved

  • Rapid and accurate detection of target substances in samples
  • Enhanced sensitivity and specificity in detection methods

Benefits

  • Improved efficiency in target substance detection
  • Early identification of harmful substances in various samples

Commercial Applications

  • Diagnostic testing kits for healthcare facilities
  • Quality control tools for food and beverage industries

Original Abstract Submitted

A method of detecting a target substance in a sample includes introducing into wells the sample, a first specific binding substance which is for the target substance and labeled with a first single-stranded nucleic acid fragment, and a second specific binding substance which is for the target substance and labeled with a second single-stranded nucleic acid fragment, forming as a result a complex containing the target substance, the first specific binding substance, and the second specific binding substance if the target substance is present in the sample, and forming a double-stranded nucleic acid by hybridization of at least part of the first single-stranded nucleic acid fragment with at least part of the second single-stranded nucleic acid fragment; and detecting formation of the double-stranded nucleic acid, wherein detection of formation of the double-stranded nucleic acid indicates presence of the target substance.
