Multicolor whole-genome mapping for genetic analysis

Overview

Executive Statement:

A novel method for precise genome mapping and sequencing using Cas9-mediated labeling within nanochannels.

Description:

This technology is a method for mapping a whole genome using a universal multi-color mapping strategy in nanochannels that combines a conventional sequence-motif labeling system with Cas9-mediated target-specific labeling. This technique allows the detection of structural variants and enables custom labels to interrogate features not accessible to motif labeling, locate breakpoints, and precisely estimate copy numbers of genomic repeats.

Market Applications

  • Detection and analysis of genetic disorders and pathogenic conditions
  • Detailed genome mapping in research and clinical settings
  • Investigating mutagenesis and quantifying copy numbers

Key Advantages

  • Ability to detect features not accessible to motif-labeling
  • Precise location of breakpoints
  • Estimation of copy numbers of genomic repeats
  • Cost-effective alternative to long-read sequencing technologies

Problems Solved

  • Difficulty in characterizing structural variants with short-read sequencing
  • Inability to precisely locate breakpoints or estimate copy numbers
