Background:

  • Ancient DNA (aDNA) offers insights into human history, including kinship and population studies.
  • Sex identification from aDNA is crucial for understanding ancient populations.
  • Existing methods for aDNA analysis can be labor-intensive and prone to contamination.

Purpose of the Study:

  • To develop and validate a microfluidic device for efficient and reliable sex identification of ancient human DNA samples.
  • To streamline the sample handling process for aDNA analysis.

Main Methods:

  • DNA extraction from powdered bone samples.
  • Labeling of abasic sites within the DNA with biotin.
  • Isolation of biotin-labeled DNA using streptavidin-coated superparamagnetic particles.
  • Amplification of the Amelogenin sex marker for sex determination.

Main Results:

  • Successful operation of the microfluidic device for aDNA sex identification.
  • Demonstration of an efficient sample handling process.
  • Reliable identification of biological sex from degraded ancient DNA samples.

Conclusions:

  • The developed microfluidic device provides an efficient method for ancient DNA sex identification.
  • This technology can enhance the study of ancient human remains and archaeological populations.
  • The streamlined process improves the accessibility and accuracy of aDNA sex determination.
