Area of Science:

  • Biotechnology
  • Molecular Biology
  • Cell Biology

Background:

  • Single cell heterogeneity is crucial in biological processes.
  • Distinguishing cells with specific mutations aids clinical diagnosis and drug screening.
  • Current single-cell detection methods often require specialized instruments and can be unwieldy for joint measurements.

Purpose of the Study:

  • To develop a low-equipment requirement platform for rapid and parallel screening of single cells.
  • To enable simultaneous analysis of target genotype and antigen in individual cells.
  • To combine genetic and phenotypic information for precise cell type distinction.

Main Methods:

  • A gel plate platform was developed for integrated cell lysis and immobilization during gel solidification.
  • Antibody hybridization and real-time amplification were performed sequentially on immobilized single cells.
  • Preservation of original loci information allowed for combined genotype and phenotype analysis.

Main Results:

  • The gel platform successfully distinguished cell types based on target gene and antigen phenotypes.
  • The method integrated cell lysis, immobilization, antibody hybridization, and real-time amplification.
  • Combined analysis of genotype and phenotype information was achieved for individual cells.

Conclusions:

  • The developed gel platform offers an easy-to-use solution for single-cell analysis.
  • This technology has potential applications in point-of-care diagnostics and high-throughput single-cell studies.
  • The platform's efficiency and simplicity are advantageous for demanding research and clinical settings.
